Don’t test your luck: food safety and pot lucks

Happy Easter!

Our church, Presley Chapel UMC.
We'd love to have you join us!

Our little church has an Easter tradition of a church pot luck after the egg hunt.  As I was making my dishes on Sunday morning, and loading them in the back of my car for the ¾-mile trip to our country church, my meat-scientist husband and I had several discussions about the safest preparation and storage plans for our dishes. That got me thinking that lots of people probably have questions about preparing, storing and traveling with food for a potluck.

Food safety is especially important at potluck dinners because you are preparing food for a wide variety of people, including vulnerable people like the elderly, or the sick, or small children. The food is more likely to sit out a while before being served, and lots of people have probably handled it. As with any food prep, be sure to remember the 4 steps of food safety Clean, Cook, Chill, and Separate. Other than that, I have a few other thoughts specific to potluck foods.

First, clean.

Be sure to wash your hands and make sure your utensils and dishes are clean. Sometimes, my casserole dishes get a little neglected in the back of the cabinet, so I washed them before I started. Deadly bacteria may live on dust and adding wet food and warm temperatures can stimulate them to grow and produce toxins that make people very sick, very fast.

Separate.

Make sure you keep foods that you plan to cook, like raw meat and eggs, separated from those that you will eat without cooking, like breads and fresh fruit and vegetables. Keep the dishes and utensils separate, too. When there’s space, I try to prepare uncooked foods in a completely separate part of the kitchen than ready-to-eat foods.

Cook.

When you are preparing a dish for a potluck, it is especially important to use a meat thermometer on meats and dishes containing eggs. Make sure you get things cooked to 160°F (165°F for poultry).  Even dishes that don’t contain meat should probably be cooked to 160°F, that should help kill any bacteria that may cause spoilage or could grow during the storage times and make people sick.

(At potluck dinners, you don’t have much control on how long the dishes are held, but you can be extra cautious about cleanliness and cookery to eliminate bacteria in the dish initially. That way, fewer bacteria are present to grow in the dish before it’s served.) 

Chill.

Picnics or potlucks,
get your leftovers in the fridge!

Knowing when to chill a dish for potluck is hard. I made three dishes on Sunday morning at 8 am. I knew that we would probably not eat until after 12:15. So, I had to decide if I wanted to keep my dishes warm for 4 hours or chill them down and heat them back up. Our church is small, and we have a brand new oven in the kitchen. I decided to put them in the fridge and warm them back up before we served lunch. The main concern is to minimize the amount of time your dishes spend in the Danger Zone of temperature (40°F to 140°F)before they are served.

Cover.

When you cook your food and it reaches 160°F or higher, most of the bacteria are killed. So, keeping it covered will keep new bacteria out during the trip to the dinner. Some of the people at church on Sunday, covered their dishes with foil when they cooked it, then covered the foil with those plastic lids that come with the casserole dishes. I thought that was a great idea, once the food was cooked, it didn’t have to be uncovered until it was served. I was not as pleased with my foil covering on my dishes, but it got the job done. 

Transport.

When you live ¾ of a mile from church, you can throw the softball stuff to one side of your trunk and transport your dishes for potluck in the back of your car (The hills didn’t cause them to spill! YAY!). Most people don’t have that luxury, so you have to think about traveling with your potluck dish.

My best advice is simply to keep hot foods hot and cold foods cold.

Use a cooler with ice packs for cold dishes like coleslaw or deviled eggs. If a cooler is too bulky, you might just pack some ice in a large baggie and place your dishes on it. For warm dishes, there are some great thermal casserole carriers that you can buy or put them in a cooler to keep them warm. If you don’t have far to go, just wrapping the dishes in towels will help keep them warm.

Reheat.

If you need to reheat your dish, be sure to use a thermometer and heat it to 160°F. Take the temperature in a few places in the dish. Some ovens don’t heat evenly, especially older ones, and you want to make sure the whole dish warm.

Leftovers.

Just like at home, you don’t want those leftovers to set out at room temperature for more than 2 hours. Get them covered and in the fridge as soon as you can.

Other thoughts.

·       Preparing single-serving items, like fried chicken, green bean bundles, or deviled eggs, minimizes the number of people who handle the food, which would minimize the chances of contamination.

·        You may consider listing any allergens that your food may contain on an index card to accompany your dish. Common allergens include wheat, dairy, eggs, tree nuts, peanuts, shell fish, fish and soy. If there are people with diabetes in your crowd, you may think about making dishes without sugar.

·        If you have a good distance to travel, you may consider making dishes that are less likely to spoil. For instance, you may make a savory green bean bundle rather than the classic green bean casserole with cream of mushroom soup. Salty and sugary dishes are less likely to spoil that dishes that contain more cream and mayonnaise.

·        When taste-testing your dishes, be sure to use a new spoon every time. Don’t be a double dipper.

·        If you’ve been sick, just go buy something from the store for the potluck. Fried chicken, drinks, ice. Don’t try to prepare anything. You don’t want to spread your illness.

I love potluck dinners, but they can be dangerous if people are not careful about food safety. I hope that you can feel a little more confident about preparing food for them in the future. Please ask me any questions you may have in the comments.

Don’t judge cooked meat by its color.

Just… don’t.

Everyone, myself included, does it. We look at the color of the inside of a burger or chicken to determine if it’s cooked. Is it pink? Nope. Chomp chomp!

Here’s the problem: Color is not a good indicator of safe cooking temperatures. You have to use a meat thermometer to be sure meat is cooked to safe temperatures.

Meat turns from pink to brown because the protein that makes meat red (myoglobin) is denatured as it is cooked. The protein is damaged and doesn’t reflect light in the same manner anymore, so the meat appears brown.

Lots of factors can affect how quickly or slowly the protein is denatured as it is heated. Meat color changes can vary due to the pH (acidity) of the meat, the age and gender of the animal, how long it was stored, the way it was packaged, whether it was frozen, even the feed and water of the animals can affect cooked meat color.

Sometimes meat turns brown too soon!

Meat scientists call this phenomenon Premature Browning. It can be really dangerous because meat looks done, but it hasn't been cooked to a safe temperature.

This photo is from a great fact sheet about beef color from the National Cattlemen’s Beef Association. Both of these patties were cooked to an unsafe temperature (55°C or 131°F). Patty A looks very undercooked, but patty B looks done.

I have a previous blog post about fresh meat color. Remember that we talked about meat being oxygenated (red), deoxygenated (purple), or oxidized (brown)? Researchers at Kansas State found that when patties were cooked in the oxidized (brown) state, their cooked color was brown, even at temperatures that were too low to kill deadly bacteria like E. coliand Salmonella. Other research has found that the packaging can cause meat to brown faster, too.

Regardless of why the meat turns brown at too low of a temperature, sometimes it happens. The best way to insure that your meat is cooked properly is to use a meat thermometer.

Ground beef should be cooked to 160°F and poultry should be cooked to 165°F.

Sometimes meat stays pink too long!

Meat scientists call this phenomenon Persistent Pinking. It is not as much a food safety issue as it is a perception and eating quality issue. When meat looks pink, even if it’s been thoroughly cooked, people will think it’s undercooked and will keep cooking it until its way overcooked. When it’s overcooked, it tastes terrible.

I am conducting research on persistent pinking in ground beef this summer. 

These patties were all cooked to exactly 160°F.
You can see how some of them are still pink in the middle.

Research has shown that a high pH (more basic) can protect the proteins at greater temperatures and keep them from turning brown. They may also stay pink because of a higher concentration of the myoglobin protein. Right now our research is creating more questions than answers, but it sure is interesting.

Persistent pinking can also be caused by outside substances interacting with the meat and creating the pink color.

Nitrites are a good example of one of these outside substances. Sometimes we want this pink color to appear, like in the case of ham, sausages, or bacon. However, very small amounts of nitrites can get into the meat (especially poultry) and create a pink color that kind of looks like ham. If you don’t expect the meat to be pink and it is, you may think it’s undercooked.

These pictures were sent to me by Dr. Jim Claus at the University of Wisconsin. He is one of the leading researchers in persistent pinking in processed meats. These are a pair of turkey slices and some tuna chunks with persistent pinking problems. All of these were cooked to a safe temperature, but some clearly have some color issues.

This is a pork chop that was cooked wrapped in bacon. Looks like the nitrites in the bacon seeped into the pork chop and created a pink color.

Sometimes the ovens that cook the meat can introduce gasses that react with the muscle and cause it to turn pink. We like it when this happens in smoked meats, but when you don’t expect it, you may be concerned it hasn’t been cooked enough.

This is a smoked sausage from an awesome BBQ restaurant in south Texas. See how the smoke has created the ring of pink around the edge of the sausage?

When you see pink color in meat, look to see where the off-color is within the pieces. Undercooked meat will be pink in the middle, but persistent pinking issues are more likely to occur on the surface.

Even what the animals (especially birds) eat or drink can introduce substances that can change the cooked color of their meat. Nitrates and nitrites that occur naturally in the feed and water can remain in the birds and create some color problems, especially around the bone.

This is another picture of some cooked chicken pieces from Dr. Claus. You can see some really severe pinking problems in them.

If you are served something that you think looks underdone, it’s OK to ask what temperature it was cooked to. Sometimes meat is just stubbornly pink, but sometimes it may actually be underdone. When it comes to my kids, if I think a piece of meat they've been served may be underdone, you bet I'll ask the waiter about it. 

The best way to know is to use a meat thermometer.

Cook it to a temperaturenot a color.

The USDA has a great fact sheet about meat color that gives more detail about persistent pinking and premature browning.

the Mom in the Livestock Barn

Today, I am going to step away from the Meat Counter and become the Mom in the Livestock Barn. I became the Mom at the Meat Counter largely because of my involvement with FFA, and my favorite activity in FFA was exhibiting livestock (mostly sheep and a few pigs). From 5th grade to my senior year in high school, my family attended hundreds of livestock shows from Houston to Denver and just about everywhere in between. I married into a cow-showing family, so, now, my family enjoys exhibiting sheep and cattle at fairs.  



My daughter exhibiting her first calf, Water Lilly. It was a special class for bottle calves and small children.


Thousands of people take their kids to the County Fair, State Fair or the Stockshow and Rodeo in their city every year. Probably more like millions. Great! What a great way to learn about food and agriculture and spend time with your kids. Go! Enjoy!

When you go to the fair, you and your family will see and hear (and smell) things that are new and different from your everyday lives. You probably have lots of questions and, if you’re like me, you don’t know who to ask and you’re afraid of being out of place or in the way. Don’t worry. We know about this stuff because it’s what our family does and what our kids are into. Your family may be into karate or competitive cheerleading or chess. If we went with you and your family to a karate match or cheerleading competition or chess tournament, we would have just as many questions and would feel just as out of place.


So, I have been thinking about some tips that I could share with other moms when they take their kids to the fair.

1. If you want to pet an animal, ask its owner, first. Animals at the fair are gentle, but they may not be used to small kids, so be sure to ask someone before you pet or let your kids pet any of the animals. Most fairs have a petting zoo, where kids can pet ‘til their heart’s content.



This is my daughter at the petting zoo at the National Western Stock Show in Denver.
It was free, so we were regulars.




2. Don’t let kids stick their hands or toys (or anything) in the pens with the animals. My sister once had a pig named Fido because he would bite like a dog. Rabbits are known to bite, and little fingers look a lot like worms to chickens.

3. Put the bottles and snacks away. The animals at the fair are clean and healthy, but there are still bacteria from their poop that may be on them that could make you sick. So, keep your snacks and bottles in your bag.

4. Keep kids hands out of their mouths and away from their faces, too.

5. Make sure you wash hands before you eat. In fact, go wash them after you leave the barn. Wash with soap and warm water for 30 seconds. I would wash the kids’ faces, too.

6. You may want to bring a small bottle of hand sanitizer along. Most fairs have sanitizer stations in the barns and outside the petting zoo. Hand sanitizer is okay for right after you leave the barn or petting zoo, but washing with soap and water for 30 seconds is best. If you use hand sanitizer, make sure young kids rub it until it’s dry. If they eat it, it could make them sick.

7. Don’t push baby strollers down the aisles in the cow barns where the cows are walking. Most cows are not used to baby strollers and it may scare them. If you want to see the cows, watch from the main aisles, or carry small children. You don’t want to get cow poop on your wheels anyway.

8. I would keep strollers and small kids out of the way of pigs, too. Pigs are low to the ground, but they will weigh 200 to 280 pounds. There are usually ways to get to see the animals without worrying about being stepped on.


9. Ask questions. People who bring animals to the fair are there to show them off. The kids are proud of their projects. They have been working with them for months. Encourage your kids to ask the kids who are showing questions. Here are some good ones.


a. What is your animal’s name?

b. Is it a boy or a girl? How do you tell the difference?

c. How old is he (or she)?

d. Have you already shown? How did you do?

e. What do they eat?


Most fairs and shows will have an area where kids can go to learn about livestock and all of agriculture. Go check it out. Sometimes there are even hands-on exhibits and games to play. Check out the fair website to know where to go.



Sorry about the flash. Here she is at the Farm Bureau Booth at the Southwestern Stock Show in Ft. Worth. Notice her pig ears.

Lastly, you may have some questions about Swine Flu and catching the flu from pigs. The pigs at the fair should be healthy, but if you are concerned, I would encourage you to check out the CDC’s page. All of the precautions listed above should keep your family safe. And, for a little entertainment, you could always check out Putnam Pig’s views on the subject.

So, go! Have fun! Ask questions! Eat lots of good food! Learn about agriculture! Come back and tell me how much fun it was!

Merry Christmas and Travel Safely

This week’s blog post comes from a Meat Counter Mom with a heavy heart. My good friend, Dr. Chris Raines was killed in a car wreck this weekend. Chris and I were friends and roomies in graduate school. Chris sent me my first-ever text message. It was about an apple-cinnamon bacon project we were going to try. Although Chris was younger than me, I looked up to him in the digital world. He was the innovator. He was tweeting before I knew that it wasn’t something that birds did. He started a meat blog long before I ever considered it. And, when I decided to enter the twenty-first century and start a blog and a Twitter, it was Chris that I consulted (via text message). It was his idea to make my blog a ‘Mommy’ blog.

He was silly and goofy and a great guy to be around. He was incredibly smart, but he could talk to anyone. He was really concerned that people were well-informed. Teaching and educating were his passions. My last correspondence (a text) with him was about helping students (his at Penn State and mine at Arkansas) prepare for an academic competition.

 I will miss him so.

This is a pic of Chris, me and our other roommate, Julie (she’s a veterinarian, now).

But, my blogs are not really supposed to be about me and my issues. My blogs are supposed to be about information that other moms need to keep their families safe and healthy. I just wanted to share about Chris and let everyone know what a great guy he was and that without him there would be no Mom at the Meat Counter.

On to the info…

Everyone seems to travel during the holiday season. If you are not headed to a grand parent’s (or multiple grandparent’s houses) for the holiday, you may be headed to the beach or the ski lodge in the next few weeks. Our family has traveled to Denver in January the past few years to stand in the cold and look at cattle.

Everyone is traveling. Money is tight and if you have a freezer full of meat, you hate to travel and have to buy meat at your destination.

But, how do you get it there safely?

First, is it frozen? Frozen meat is the easiest to travel with. If you have some steaks or roasts in the fridge that you want to travel with, freeze them. Freezing for a few days won’t hurt their eating quality. Frozen meat has further to go before it reaches the DANGER ZONE.  

If you are going to travel more than an hour or so, you’ll want to pack your meat in a cooler. Make sure you wash the inside and outside of your cooler before your fill it with meat. You also want to save packing the cooler as one of your last chores before you head out the door. That will minimize the time the meat is in it.

You want to fill the cooler as full as possible, so use as small a cooler as you can. Excess air in the cooler will cause the meat to thaw faster. If you can’t fill your cooler up with meat, put a towel or blanket inside the cooler to insulate the air. You’ll want to put the meat on the bottom and the towel on the top. Air will escape into and out of the cooler through the lid, so you want to insulate it from the top.

For trips shorter than 5 or 6 hours, frozen meat will probably stay frozen in a cooler, especially in cool, winter weather.  If you are going to be traveling for longer periods, you can use those frozen, blue ice packs. Pack them next to the edge of the cooler and on top of the meat. Think about where the warmth will be coming from, the top and the sides.  Don’t put ice on frozen meat, the ice may actually be warmer than the meat, and, because it will melt into water, ice will thaw the meat faster than air would.

Some people may consider dry ice. Dry ice is frozen carbon dioxide. You can use it to keep meat frozen, but it can be dangerous if you keep it in the car with you or if it touches your skin. Follow the link and read about the safety of dry ice before you decide to use it.

If your meat is not frozen, you can still travel with it. Here is where I would suggest using ice. It would be best to package any meat you are traveling with in water-tight packages, like zip-lock bags. If the meat is already in a vacuum package, it will be fine. Put the meat on the bottom of the cooler and the ice on top of it. Meat freezes at a lower temperature than water (28° F), so the ice will not freeze the meat. You can use the ice as an indicator of the cooler temperature. As long as the ice is solid (you know, still ice) the meat should be cold enough. If the ice thaws, drain out the water and buy more ice.

If you packed fresh, uncooked meat, the ice could have harmful bacteria on it. Don’t use it for drinks or anything else. Just throw it out.

After you’ve packed your cooler, you may consider putting a blanket over it, especially around the openings. That should help insulate any warm air that may try to seep in it. If it’s cold outside and the car will be warm, put the cooler in the trunk or back so it will stay colder. Also, try to minimize how many times you open it. Every time you open the cooler, all the cold air will escape and will be replaced by warmer air.

I hope everyone enjoys this Holiday Season and has a Merry Christmas and a Happy New Year. I hope you get to enjoy your family and that you eat well. But, please… Travel Safely.
