    The antibiotic age

    Last month, I attended the Alltech ONE ideas conference. Alltech is a global company that produces lots of different products that may be used in many segments of agriculture. Every year, they host a group of bloggers to their conference and ask us to write about what we learned. This was my fourth year to attend, and I would love for you to see what I’ve learned at previous Alltech conferences.

    This year, several of the sessions I attended covered the topic of antibiotics. Alltech is a forward-thinking company that is working to reduce the use of antibiotics in food production. They offer feed supplements that farmers can use to keep their animals healthy and productive rather than using antibiotics.

    There were also several discussions about sustainable energy and the use of fossil fuels. During one of those discussions, the speaker, Ramez Naam, shared a quote from a former oil minister of Saudi Arabia.

    He said, “The stone age came to an end, not because we had a lack of stones, and the oil age will come to an end not because we have a lack of oil.”

    That discussion was about oil and energy, but I think that the premise can be applied to antibiotics.

    Agriculture has changed a great deal in the past 6 decades. Our population is growing at a staggering rate, and farmers have had to adapt to meet the demands for food in our world. Getting to this point in agriculture has taken lots of tools and one of those tools has been and still is antibiotics.

    I have written about antibiotics before. People have trouble understanding the use of antibiotics in food production; the fact that some bacteria adapt to become resistant to them, and that farmers use antibiotics to help keep their animals healthy and are careful to treat their animals in such a way that antibiotic residues don’t end up in our meat. Farmers and consumers have concerns about bacteria becoming resistant to antibiotics, and, in food production, antibiotics are at the front of everyone’s mind.

    We have to remember that the Stone Age didn’t end overnight. People slowly figured out new and more efficient ways of doing things. They found new materials and new ways to use old materials. Then, their ideas spread around the world.

    We can’t expect the use of antibiotics to end overnight either, but things are happening quickly. Farmers are using a whole-systems approach to improve animal health. Meanwhile, animal scientists are figuring out new ways to help farmers produce healthier animals without the use of antibiotics or with a vastly reduced use of antibiotics.

    At the conference, Dr. Aiden Connolly, talked about several ways that animals may be managed to help reduce or eliminate the use of antibiotics.

    Genetics: Everyone has that friend who never gets sick. The same happens in the animal world. Some animals are just better at fighting disease on their own. Now, we have the ability to find those specific genes in animals and select for them. By breeding the healthiest females to the healthiest males, and eliminating the more sickly ones, fewer animals will get sick and fewer will need antibiotics.

    Biosecurity – health management: In a previous post about antibiotics, I jokingly mentioned that you can’t teach pigs to wash their hooves, but we can manage the humans and the equipment going in and out of farms to keep disease from spreading.

    In April, I went to two pig farms in one day, and I took four showers that day. On modern swine and sometimes poultry farms, humans are required to shower in and shower out. That means you take a shower, and only wear clothes that belong to the farm. Even underwear (TMI, sorry). Other precautions included washing the vehicles that we drove every time we entered a new farm, keeping wildlife away, and limiting visitors.

    Sanitation and reduced contamination will reduce the exposure of animals to bacteria that cause disease, and will reduce the need to treat those animals with antibiotics.

    Nutrition: Keeping animals well-fed and healthy will help their bodies naturally fight disease. Scientists are also learning how to create an environment in the animal that promotes health and fights bacteria without antibiotics.

    Gut health and the Microbiome: Last year I wrote a post about the human microbiome, but animals each have their own microbiome. Dr. Stephen Collett, from the University of Georgia, spoke at the conference and he said that when we choose animals for breeding, we are not only selecting their genetics, but also their microbiome. Mothers pass their healthy bacteria to their babies, and all animals share it in their barns, pens, and fields.

    The interactive effect of a healthy gut and nutrition is so important. Farmers are learning to feed the good bacteria to fight the bad ones. Dr. Collett said, “We can’t win the war on disease by killing, we have to win by multiplying. We have to nurture what we want.” Using nutrition to feed the healthy bacteria will lessen the need for antibiotics to fight the bad bacteria.

    The day after the conference, I watched a webinar by some animal scientists from Texas A&M. They spoke about bacteriophages, viruses that kill specific bacteria. They exist everywhere in nature. Some animals naturally carry them in their guts to help them fight bacteria that might make them sick. Obviously, bacteriophages are part of the microbiome. Scientists are learning more about them and how they can help fight bacteria every day. 

    Keep moving forward.

    Farmers and scientists are adapting every day to how we fight disease and pathogens in food animals. With every new break through, we have another tool in our toolbox to fight dangerous bacteria. One of the exciting things about working in the food industry is that it is constantly changing.

    There is no way our industry is ready to completely stop using antibiotics, but we are finding ways to use fewer antibiotics all the time. The whole industry will continue to keep moving forward to a new age of total animal health. 

    The founder and CEO of Alltech, Dr. Pearse Lyons, has a great quote that I think can be applied to the transition away from antibiotics, “Don’t get it right. Get it going.” Changing the tools we use to produce food for 9 billion people is not going to be easy, but we have to keep moving forward. Get it going.

    You will never be lonely again ~ a Meathead’s take on the Microbiome

    I was invited again this year to attend the Alltech Symposia to learn about new and emerging technologies in agriculture and food production. Alltech is a global food and Ag company that produces feed ingredients and supplements for all parts of agriculture including cattle, swine, fisheries, equine and crops. They view agriculture as a whole food system, and are very interested in tackling global health issues with solutions applied to food and crops.


    One of the most interesting sessions I attended covered the Microbiome, led by Dr. Rowan Power, an Alltech scientist.

    He said that we used to say, “You are what you eat.”

    But now, he says, “You really are what 100 trillion and one of you eat.”

    Each person plays host to about 100 trillion bacteria (that doesn’t even count fungi and viruses). These bacteria live on and in your body, including on your skin, in your nose, mouth and eyes, in your lungs, and, of course, in your digestive tract. Over 1,000 species of bacteria live in your intestine, mostly your lower intestine. Yummy.

    A few more facts about your microbiome:

    • Bacterial cells out number human cells 10 to 1
    • The microbiome comprises 1 to 3% of your body mass (that’s 2 to 6 lbs on a 200 lbs person)
    • The total microbiome may consist of 10,000 species
    • The bacteria in our gut allow us to digest foods
    • The number and variation of the bacteria will vary from person to person


    Microbes and weight loss

    Doesn’t everyone have that one friend who can just think about going on a diet and lose 5 pounds? Scientists like Dr. Power are finding that the way our bodies react to changes in what we eat is largely dependent on the bacteria in our gut. What we eat is not as important as what the bacteria in our gut do with the food we eat.

    In one study, scientists removed the gut bacteria from some lean mice and introduced it to mice that were completely germ free.  They did the same with bacteria from obese mice. The mice that were given bacteria from the lean mice became lean, and those given the obese mice bacteria became obese. So, the bacteria in your gut may have an impact on how lean or obese you become.

    Dr. Power also said that when scientists looked at the bacteria in lean people, there was more variation in the bacteria in their guts than in obese people. People with more variation in their diets had more variable bacteria to digest their food and were leaner. (Makes me second guess my oh-so-consistent breakfast routine.)







    Microbes and feelings

    You know how some foods make you feel so good? Most neurotransmitters (the chemicals that send signals within and from our brain) are derived from nutritional factors. So, the way our microbiome breaks down food can actually affect how good we feel. Get me some happy bacteria!

    How do we change our microbiome?

    The microbiome will change based on what you feed it. If you eat a diet of fat and sugars, your microbiome will adjust to digest fat and sugar. If you eat more leafy greens and vegetables, the bacteria will change to digest those. So, the more variety in your diet, the more variety in your microbiome.

    Medicines like antibiotics can also change your microbiome. Everyone has been a little sick to their stomach after taking antibiotics (or you’ve had a sick child that has developed a nasty diaper rash after being on antibiotics). Even the bacteria on your skin can be affected by antibiotics. This is why doctors suggest that you eat yogurt after you’ve had to take antibiotics. Yogurt is full of healthy bacteria and you need to re-populate your gut with healthy bacteria after you’ve had antibiotics.

    Scientists are figuring out new ways to alter the microbiome in humans and animals all the time. There are foods and supplements that can encourage the growth of good bacteria and discourage the growth of bad bacteria. Of course, we all know the benefits of eating yogurt and drinking acidophilus milk. Cattle farmers have been using feed additives called ionophores to optimize the microbiome in their stomachs and help cattle digest feed more efficiently for years.

    Dr. Power said that pretty soon, human health efforts will encompass care for the human as well as care for the microorganisms that live on and within the human. We may be able to treat chronic diseases in humans by treating and altering the bacteria that live within them.


    Personally, I am excited about this emerging science in microbiology. I think it will be neat to see the medicine and treatments for diseases like Krohns and diabetes that might emerge from our new understanding of the microbiome.

    Antibiotics in the meat supply: Residues vs. Resistance

    There has been a lot of news coverage and proposed legislation lately calling for the banning of antibiotic use in farm animals. People can get very frightened when we talk about antibiotic resistant bacteria or antibiotics in the meat supply.
    This has been an especially personal topic for me because our family recently had a scare with antibiotic-resistant bacteria. In May, my daughter had a little lump behind her ear. I found it over a weekend and by Sunday evening, she was running a low fever, so we went to the doctor on Monday morning. By 6pm, we were admitted to the hospital with a very high fever and a freshly-lanced abscess. It took 2 of days of testing, and she was diagnosed with MRSA (methicillin-resistant staphylococcus aureus). She spent three nights in the hospital on IV antibiotics. Now, she’s fine and back to her little rotten self.
    MRSA - Antibiotic-resistant Staph
    Experiences like ours are very scary, and I know there are a lot of parents with much worse stories to tell than mine. However, most people know very little about antibiotic-resistant bacteria like MRSA. When they hear about antibiotics in relation to our food supply, they don’t know what to think.
    First, what exactly are we talking about?


    Antibiotics administered to animals headed to the food supply.

      
    Why are animals given antibiotics?
    There are two main reasons why animals are given antibiotics.
    1. The most obvious reason is that animals are given antibiotics when they are sick or injured to fight infection.
    Most people agree that it would be inhumane to withhold a drug from a sick animal and allow it to suffer. Even organic farms and antibiotic-free farms have a protocol in place to treat a sick animal and remove it from their herd.

    2. Sometimes animals are given antibiotics to prevent them from getting sick. 
    Just like kids, young animals are prone to infection. In some farms, animals live very close to one another and they are not very clean creatures (you just can’t teach a piglet to wash his hooves), so if one gets sick, they could all get sick very quickly. That could spell disaster for a farmer, so some farms choose to feed a low level of antibiotics to prevent disease.

    3. Some antibiotics are given to improve how fast and efficiently animals grow.
    There are new rules about antibiotics from FDA as of June 2015. I'm doing some research on them to make sure I understand them before I share what they mean in this post. Thanks for bearing with me. 
      
    You may have heard a statistic in a news story that said that 80% of the antibiotics sold in the US are given to livestock animals. That number is largely disputed. First, it is impossible to know how many antibiotics are sold in the US, for use in livestock or in humans. Second, a large percentage of drugs used by farmers are not useful in human medicine. Lastly, livestock represent a larger population of bodies than do humans. And, cows and pigs are a lot bigger than humans; pound for pound, they need more antibiotics. What is the real number? Who knows?

    What about antibiotics in my meat?
    When people in the food industry talk about antibiotics, there are two terms they use: antibiotic residues and antibiotic resistant bacteria.
    Antibiotic residues’ refers to actual antibiotic chemicals that have been given to the animals, either fed or given as injections, remaining in the edible tissue (meat, fat, or even milk).
    The Food and Drug Administration regulates the approval and use of antibiotics in animal medicine. Any antibiotic that is given to a food animal has a specified ‘withdrawal time’ which is the amount of time that the antibiotic has to be withdrawn from the animal before it is slaughtered. These times are based on how long it takes the animal to process the antibiotic so that it is eliminated from the body. Farmers must wait to slaughter an animal for that amount of time after giving the antibiotic to the animal or they will be breaking the law.
    The Food Safety Inspection Service (part of USDA) monitors the meat supply and tests for antibiotic residues in the meat. The levels of antibiotic residues found in the meat supply are very low (below 1%), and tests are done on a worst-case scenario basis, which means FSIS tests the tissues that are most likely to contain antibiotic residues (liver and kidneys) and they test a larger percentage of suspect animals (old cows, animals with injection scars, etc.). Although the levels are not zero, I am not really worried about antibiotic residues in meat.
    A group called the US Farmers Ranchers Alliance has a video of experts discussing antibiotic residues.

    Antibiotic-resistant bacteria’ refers to bacteria that are not easily killed by common antibiotics, they are resistant.
    How do bacteria become resistant to antibiotics?
    Bacteria are everywhere, and there are millions of species, strains, and serotypes… all fancy ways of saying ‘different’ bacteria. Bacteria have a genetic code, just like humans, and they change and evolve with each generation. Unlike humans, they multiply at crazy-fast rates, so their genes can change at fast rates. When you introduce something to kill the bacteria like antibiotics, most of them die, but a few live. The ones that live may have had something in their genetic code that allowed them to survive the antibiotic treatment. All the other bacteria are gone, so that leaves more room and food for the left over bacteria to grow. When they grow, they pass their antibiotic-resistant genes to the next generations. Eventually, those antibiotic-resistant bacteria are spread around, and found all over the place. We have to learn to fight them in different ways.
    A study from 2003-2004 found that MRSA (the bacteria my daughter fought) was in 1.5% of American noses. That was 8 years ago, and the bacteria have been spreading since then, so the numbers are probably larger now.
    Are antibiotic-resistant bacteria in my food and how did they get there?
    Yep. Antibiotic –resistant bacteria are in our food supply. They are everywhere.
    Our food is handled by several different people and goes through several steps to get to our plates, and bacteria can be introduced at any of those steps. Some people want to blame the use of antibiotics in animal feed and that may be part of it, but it is likely that several actions contribute to the spread of antibiotic-resistant bacteria.
    Can it make me and my family sick?

    There are some forms of dangerous food borne pathogens like Salmonella and E.coli that have developed some resistance to antibiotics. That means that if you get one of these bacterial infections in your gut, it will be harder for doctors to help you fight them. But, even the non-resistant forms of these bacteria are very dangerous and can make you very, very sick.
    What can I do?
    Antibiotic resistant bacteria are susceptible to foodsafety measures such as cooking food thoroughly and keeping raw food away from cooked food. 
    • Cooking kills antibiotic-resistant bacteria just like it kills antibiotic-susceptible bacteria. Use a meat thermometer to be sure you cookmeat thoroughly
    • Hot soap and water wash antibiotic-resistant bacteria off of counter tops and utensils. 
    • Antibiotic-resistant bacteria cannot grow as well in cold environments just like the antibiotic susceptible strains, so getting fresh food and leftovers chilled quickly is very important.
    • Antibiotic-resistant bacteria can’t jump through the air from raw food to cooked food, so keep raw and ready-to-eat foods separate.
      
    Anything else?

    The main two bacteria species that we hear about when we talk about antibiotic resistance are Staphylococcus aureus (MRSA) and Clostridium difficile. Although they are huge issues in the medical industry, the CDC does not see them as a risk in the meat industry. Food safety practices should keep you from getting sick from these bacteria in your food.

    However, you may have heard that MRSA has been found in 6.6% of pork samples in a US study. I emailed the author of that study for this post. She was really nice and said that the worry with MRSA in meat is not as much about getting sick from it being in your food as it is about the MRSA spreading from the raw meat to other surfaces and being introduced to a scratch or an open sore and causing severe skin infections, like the one my daughter had.

    Lots of bacteria from raw meat can cause skin infections if they are introduced to an opening in the skin, and these antibiotic-resistant ones are very hard to fight. So, my advice is to be extra careful with raw meat, especially with children (face it, they are dirty little monsters. I’ve seen mine lick the bottom of her shoe.).
    Keep raw meat separate from other food from the time to pick it out at the grocery store until you cook it.  
    • Use a plastic bag to keep raw meat away from other food items and away from surfaces like the bottom of the grocery cart.
    • Wash your hands after handling raw meat
    • Wash down the countertop with warm soapy water after it came into contact with raw meat (even in the package)
    • If you have a cut on your hands, wear gloves when handling raw meat (like when you make hamburger patties.)
    • Don’t let very small children handle or be in contact with raw meat
    My friend Karen sent me this picture of her grocery cart. Her roast is in its package away from the rest of her food. Looks like she put a piece of butcher paper under it. Way to go Karen!


    There have been studies connecting antibiotic-resistant E. coli bacteria from chicken to urinary tract infections. If I have been handling raw meat, I wash my hands before AND after going to the restroom.

    I called and asked the pediatrician if there was any way to know where the MRSA that infected my daughter came from, and there was not. The doctor told us that lots of people are infected with it and kids ‘pick their nose, then pick their wounds.’ Gross.

    What about buying meat from animals that have not been given antibiotics?

    There are companies and farms that offer meat from animals that have never been given antibiotics. I’ve talked about such programs in a previous blog post. If you choose to buy those products because you want to support the practice of never giving animals antibiotics, that’s fine, but you should know that meat from these farms are not guaranteed to be free from antibiotic-resistant bacteria. The meat is not any safer than the meat that does not make that claim. A recent study found that the levels of Staphylococcus aureus and MRSA in pork were the same regardless of it being from pig farms that did not use antibiotics.

    Denmark has banned the use of sub-therapeutic antibiotics and the results have not been positive for their pork industry. Jeff Fowle, a rancher and blogger from California discusses the ramifications of Denmark's decision in his blog.

    Like I said earlier, there is lots of info on the internet about antibiotics (residues and resistant bacteria) in meat and in general.

    I don’t know all the answers. Here is a list of a few more resources if you are interested.

    Getting the kitchen ready for the holidays

    Now that we’ve switched back to the ancient, standard time, and we all get home after dark; we seem to be stuck in the house for endless hours every night. (I really don’t see much point in switching back to standard time every year; except that it makes us all appreciate day-light savings time when it comes around again in the spring.)

    So, what to do with all those extra hours trapped in your house with your family?

    One great idea is to clean out the fridge! Yay!


    With all the ‘hustle and bustle’ of the holiday season, it’s easy for your fridge to get packed in just a few short, crazy weeks. So, the week or two before Thanksgiving (right after we fall back) is the best time to clean out the fridge and get it ready.

    I always try to clean out my fridge on the night before the trash man comes, because room-temperature, out-of-date fridge contents can get pretty stinky sitting in the trash can. Check the dates (sell-by, freeze-by, or use-by dates) on all your deli meats, hot dogs, and cheeses. This is also a good chance to double-check your mayonnaise, salad dressings, and salsa, pretty much anything that’s perishable.

    I know that the dates are sometimes hard to find, so I took some pictures to give examples of where dates may be found. I can’t tell you when or where I took these pictures (for my own protection).

    Dates may be found on the back of the package or the bottom of the label. Sometimes they are on the lids of jars or the bottoms of cans. Sometimes they are not on the label at all and are printed directly on the plastic of the jar, bottle, or package.

    Mustard, barbeque sauce, frozen foods, pickled things. These all have a ‘best-by’ date. Notice that some of my examples are out-of date and some have dates that go almost two years into the future. These dates are mostly to help insure the quality of the product. If you eat them after this date, they may not taste great, but they won’t make you sick. Now, remember that this is dependent on how the food has been handled. If it has been allowed to reach room temperature after it was opened, it may not be safe, regardless of the date.
     
    The next set of pictures represents use-by dates, and I thought they were some good examples of where to look for dates. Again, they probably won’t make you sick if you consume them after the date expires, but it probably won’t taste very good at all. Cool whip and margarine are usually used in other dishes, so you want to make sure that their ingredients are in the best condition. If you use them after the use-by date, your final dish may not be as good. The oil in ketchup will separate out as it gets older. The artificial sweeteners in diet drinks lose their sweet flavor after a few months, so that Diet Coke may taste like bitter, fizzy water. Salsa and picante sauce may fall in this category, too. I have found that they are prone to mold growth, even in the fridge. Ick….
     
    In this last group of pictures, some of the dates say “best-by” and some just have a printed date. These pictures are meats or foods largely made with milk and egg products which are good places for bacteria to grow. So, for meats, mayonnaise, yogurt, cheese sauce, and those types of products, I would stick with the dates. Throw out anything that is past the date on the package. I would put ranch dressing in this category, too.



    Ok… back to cleaning out the fridge.

    Toss out any left-over’s older than 3-days old. I am guilty of keeping leftovers until they would make good science projects, but we never eat them. We just make funny faces as they go in the trash.

    Remember that you are trying to make more room. Sometimes I find two opened packages of the same food and condense them. Empty the shelves all the way to the back. Check the date on everything in the door.

    This is a good chance to wash the refrigerator shelves and the drawers with hot, soapy water. You might also want to put in a fresh box of baking soda.

    Are you planning to thaw some large meat items in your fridge on Turkey day? (You know… a turkey.) Get a big space cleaned out so you can put it on the bottom shelf. Make sure you have a tray or plate big enough to put it in to catch the juices while it’s thawing. Also, double check that the shelf above is not too low and that your turkey won’t be touching it. Most refrigerators today have adjustable shelves, so you can make the space above the bottom shelf as big as you need it.

    You will need to allow 1 day of thawing for every 5 lbs of frozen turkey. So, be ready to share your fridge with a large bird for three or four days before Thanksgiving.
    Remember that you may have to store large casserole dishes in your fridge for a while, so make sure there is room for those too. Also, they are not very tall, so you can adjust the upper shelves closer together to save room.

    Double check that your refrigerator is cold. (Remember that the temperature will rise if you have the door open, so be sure to check the temperature after the door has been closed for 20 or 30 minutes.) I like to keep mine as cold as possible without freezing my milk, but it should be set no warmer than 38°-40°F. You want to make sure that it is 40°F or cooler in every area of the fridge, so setting it lower may be necessary.

    This is a good chance to look over your shopping list for Turkey Day. Figure out the things that you need and the things that you already have. Make sure you have a meat thermometer! Food costs are going to be high this year, so you don’t want to buy ingredients that are already in the fridge or the cabinet. For example, I think I have enough salt for thirty years because I mistakenly thought I needed salt when I was planning a big meal … maybe it wasn’t me…

    I don’t have much counter space in my kitchen, so I have to spend a little time clearing off my counters before I take on a big cooking job. You also want to wash your countertops with warm soapy water. Double check that your roasting pan and casserole dishes are clean. Sometimes, if they aren’t used for several months, they can collect dust. Make sure you have at least two good cutting boards, one for food that is going to be cooked and one for food that will be eaten without being cooked. I like to use different colored cutting boards for ready-to-eat and pre-cooked foods. I also want to remind you to keep the knives and other utensils separate for ready-to-eat and pre-cooked foods.

    Or… you could spend your evenings watching TV and go to someone else’s house for Thanksgiving. Let your Mom (and, in my case, Dad) do the cooking. That’s my plan, but I still need to clean out my fridge. ;)

    Recalls

    Nothing is more frightening than seeing a food recall or a food poisoning outbreak on the news or online. Especially when it is a very common product that you use all the time, like ground beef or cantaloupe.

    A recall means that a problem has been found with a food, and the company that produced it is removing it from the food supply. This can be for a variety of reasons from undeclared allergens (ingredients that people may be allergic to that are not on the label) to contamination with bacteria or a virus.

    One recent recall was due to people getting sick from E. coli O157:H7 infection in Ohio (not all recalls are associated with sicknesses). Scientists tested the ground beef in the people’s homes and found that it was contaminated with that strain of E. coli. Meat companies print codes on their packages that allow them to trace any package back to the plant where the meat was produced, the day, sometimes even the production line and the time of day. They can use that information and look at their records to know exactly what other packages may be contaminated with the same bacteria and where they were sold.

    How do I find out about recalls?
    Recalls of retail products are usually on the local news. If you see something being recalled on the news, you can usually find out more information by going to the news website or to the website of the company that is issuing the recall. Sometimes you may have to search ‘recall’ when you get to their site.

    I know that not everyone watches the news, so I have been thinking of some other ways to find out about recalls. Because I’m a meat scientist, the first thing I thought of was FSIS. The Food Safety Inspection Service of the USDA has a recall page on their website that you could check, but this will only cover products under the jurisdiction of USDA (meat, poultry and eggs). The FDA also has a recall page, for FDA-regulated products (all food except meat, poultry, and eggs). Both of these pages offer an option to sign up for email alerts. The webpage http://www.foodsafety.gov/ combines the food safety information from FSIS and FDA and has US food recall information on one page where you can sign up for email alerts, follow them on facebook, twitter or as an RSS feed.

    How do I know if recalls apply to me?
    The recall information should give where the product was produced and the establishment number of the processing plant associated with the recall.

    What is an Establishment number?

    Every meat processing plant is given a specific number by the USDA. Any product that exits that plant has to have the Establishment number on its label.


    If the meat being recalled is red meat and is processed (most of it will be processed), it will have an inspection mark like the one in the middle of the picture above. If it is poultry (chicken, turkey) it will be like the one on the right.

    The recall will also tell you what states the recalled product was sold into. For meat and poultry recalls, they will tell you the ‘Best-by’ or ‘Freeze-by’ dates printed on the package. When meat is packaged in a plant, the processor prints a ‘Best-by’ or ‘Freeze-by’ date on the package that allow the consumer to know when to eat or freeze the product and to allow the processor to know when the product was made (simple subtraction).

    Sometimes these dates are hard to find. They are printed on the package as the meat goes down the production line, so they are simple, one-line, almost stamp-like. Sometimes they are on the bottom of a can or on the side of the package.

    Here are some pictures of some ham I had in the fridge. Notice the inspection mark with the establishment number on the bottom and the ‘best-by’ date at the top.
    
    
    See the establishment number
    in the little circle at the bottom?
    
    
    
    The use-by date
    


    Many times when a recall is issued, people will throw out things in their fridge or freezer just because it is the same type of product as what is being recalled. I think that is wasteful. 

    Here is an example: According to the Tyson website, a product recently recalled was 73% lean ground beef sold in 3- and 5-pound packages. The chubs had an Establishment Number of EST 245D and a Best-by or Freeze-by date of September 12. The product was produced on August 23. That means if you bought some 3- or 5-pound chubs of 73% ground beef between August 24 and September 12, you should go check your freezer and look to see if your ground beef has the EST 245D and a Best-by date or Freeze-by date of September 12.
    Chances are you didn’t buy 3 and 5-pound packages of 73% ground beef. Those are really big packages and it’s the fattiest ground beef available. If you buy leaner ground beef, it is not part of this recall. Don’t just throw out any ground beef you find.

    What about buying meat at the store?

    If a recall has been issued, you shouldn’t have to worry about that product still being on the shelf at a store. Stores are very diligent at getting recalled product removed from their shelves. Stores that have had recalled product will also have information about it on their website.

    What if I find recalled product in my fridge or freezer?

    If you find product in your house that has been recalled for any reason, you can take it back to the store. I would call the store first and ask about taking it back. You don’t want to show up with it and no one knows about the recall or what to do. I say this because after my year working in a grocery store, I realized that not everyone is always on the same page.

    If the recall was for some type of bacterial contamination (E. coli, salmonella, and Listeria have been the ones in the news lately), remember to treat the recalled product with care. If you find it in the fridge or the freezer, I would take it out, put it in a big, zip-lock-type freezer bag, make sure it sealed, and put it in the freezer. That will lessen the chances of it contaminating something else. Wash your hands thoroughly after you’ve handled it. Be sure to clean any surfaces it touched (plates for thawing, refrigerator shelves, counter top) with warm soapy water. When you do take it to the store, go directly there. Don’t leave it in your car for very long.

    If you have a question about a recall, you can always just ask me. If I don’t know the answer, I will find someone who does.
