If visions of mistreated animals injected with a continuous supply of hormones and antibiotics leave you feeling confused and terrified about your food choices—this post is for you. I’m cutting through many myths about how pork is produced, so you can rest assured you are making the right choices. For this post I interviewed Wanda Patsche, a pig farmer from Minnesota.

Aren’t big farms owned by big agriculture companies?
Wanda: Family farmers own 97% of pig farms. Some farms are big some are small.

What are the greatest misperceptions consumers have about pigs?
Wanda: Many people think modern farms are less humane compared to small farms; niche farms, pasture raised. Actually, the opposite is true. With modern farms barns are designed so you can handle the pigs better; pigs have a social hierarchy where they fight with each other. Modern farms are specifically created to easily control this fighting by having pigs in individual pens. This means less stress for the pigs, plus the buildings are temperature controlled with fresh air. Pigs are given clean water and clean feed. The barns are pressure washed and sanitized between groups of pigs (when pigs move out and prior to new pigs coming in). Plus, pig farmers work closely with their veterinarians. Farms that have more pigs mean the famers continually grind feed because they have more mouths to feed. Continually grinding feed means the pigs get fresh feed. Their diets are designed for health and growth.

What you need to know about porkIs hormone-free pork better?
Wanda: No pigs are given hormones. Farmers are not allowed to give pigs hormones. Therefore, any pork labeled “hormone-free” has been given this label to try and make customers think it is better than other pork. However, there is no difference, all pork is free from added hormones.

Are there any antibiotics in my pork?
Wanda: Antibiotic-free is another labeling term to try to persuade customers to choose chose a specific pork product. All meat is free of antibiotics. If a pig is given an antibiotic, all traces of the antibiotic must leave the body—called the withdrawal period—before the pig is sent to off for pork production.

What do you think is driving these perceptions?
Wanda: In the U.S., less than 2% of people are farmers. Many people don’t know farmers, and they are 2 – 4 generations removed from farmers. If you’ve never been to a farm or know people who farm it is easier to believe the myths that circulate on the internet.

Tell us a little more about advances in pork production and the safeguards in place to ensure pork is safe.
Wanda: Forty years ago, pigs were all outside. They had clean air but many hazards including sunburn and the greater likelihood of getting worms (and therefore the vets would have to treat them with medicine for worms). Now, with the introduction of indoor facilities and individual pins, pigs are less stressed which keeps them healthier. Stress = greater likelihood of sickness.

In addition, antibiotics are used less, and there is a comprehensive vaccination program in place to keep pigs healthy. On farms that do not use antibiotics to treat animals when sick, the animals must be pulled away from the other pigs to prevent the illness from spreading.

Animal scientists are currently conducting studies examining ways to keep animals healthy including the use of essential oils, probiotics, and enzymes. Healthier pigs mean even fewer antibiotics are used.

Antibiotics are the last resort and only used when necessary.

Pigs are grouped together based on age. This is helpful as immune system functioning differs by age. This is just another step to keep pigs as healthy as possible.

Aren’t farms more concerned about quantity vs. quality?
Wanda: No. Every day I wake up and think, “what can I do to ensure my pigs are as healthy as possible?” Pig farmers get more money for higher quality meat. So, every pig farmer has an added incentive to produce healthy, high quality pigs. Lower quality pork goes to a secondary market for ground pork, pepperoni and similar process products. Farmers get considerably less money for lower quality pork.

Are there any concerns that consumers should have about pork?
Wanda: The biggest concern for consumers is how pork is handled and cooked. According to the USDA pork should be cooked to 145°F internally. Ground pork should be cooked to 160°F. It can be pink in the middle as long as these internal temperatures are reached.

What are the best cuts of pork?
Wanda: pork is 16% leaner than it was 20 years ago due to the way animals are fed and genetics. Pork tenderloin is just as lean as chicken breast. An easy way to remember this: loin = lean.

Yikes! Are there Antibiotics or Hormones in Your Milk & Dairy Foods?

Are antibiotics and hormones used in dairy cows contributing to the obesity epidemic, early puberty and antibiotic resistance? Before going down that road, we have to first we have to first ask if there are any antibiotics or hormones in milk and dairy products.

In this blog post I will cover:

  • Why are antibiotics given to cows?
  • Antibiotics are not in milk, here’s why.
  • Why are growth hormones given to cows? Are there any hormones in my milk and dairy food?
  • What are the cows Eating?

Why are Antibiotics given to Cows?

Antibiotics are used on farms to treat animals who are sick just like you would give an antibiotic to your child if he or she gets sick or take one yourself. There is no reason for dairy farmers to give antibiotics to cows who are not sick. Doing so costs additional money,  serves no clear purpose and arbitrarily giving animals antibiotics could contribute to antibiotic resistance. Now imagine you are a farmer and your life depends on the health of your cows – would you want to run the risk of antibiotic resistance and your cows getting sick with fewer treatment options?

Some antibiotics are also used for animal growth. The FDA is phasing out this practice so medically important antimicrobial drugs (antibiotics) will no longer be allowed to enhance growth or feed efficiency. In the future antibiotics will only be allowed to treat, control or prevent disease and of course require a prescription from a licensed veterinarian. Regardless of whether or not the antibiotic is used for growth or treatment of disease, no traces of antibiotic residues are allowed in milk or dairy products.

Antibiotics are Not in Milk, Here’s Why.

Any cow that gets an antibiotic is milked separately from the rest of the herd and the milk is thrown out. That milk will never be sold or consumed. All antibiotics have a different period of time before all traces of the medication leaves the body (whether we are talking about a cow or a human). Once this period is up and the cow is completely healthy again, the farmer tests her milk. Milk cannot be sold until it is completely clear of all drug residues. Whether organic or conventional, all milk is tested several times before making it to market. It is tested on the farm and at the milk processing plant. Any milk that tests positive for any medication residue, including antibiotics, is thrown out (1).

According to national Milk Drug Residue Data Base compiled for the years 2013 to 2014, 0% of milk tested positive for drug residues. In 2015, the FDA’s Center of Veterinary Medicine surveyed 1,918 raw milk samples (before pasteurization) from across the country. Samples were tested for residues of 31 drugs including the antibiotics, NSAIDs (ibuprofen etc.) and an antihistamine. They found 99% of sampled milk was free of any drug residues. Keep in mind the 1% of milk with residues must be thrown out – it cannot be sold (1, 2).

Cheese and yogurt are made from milk and therefore, there are no antibiotics in your cheese or yogurt either.

If you want to learn more about what farmers are doing about antibiotic resistance, Minnesota Farmer Wanda Patsche wrote an excellent blog on this topic.

Growth Hormones in Dairy Cows

Growth hormones are approved for use in dairy cows to improve milk production. Greater milk production means fewer environmental resources used to raise cows for milk. Bovine somatotropin (bST; also called bovine growth hormone or rBGH) is perhaps the most well recognized growth hormone used on dairy farms. bST is “a protein hormone produced in the pituitary gland of animals, including humans, and is essential for normal growth, development, and health maintenance.” Very little bST is used in dairy cows and there is no test that can distinguish between cows treated with bST and naturally occurring bST (3). Humans do not have receptors for bST and therefore it is passed through your body intact without being absorbed (4). As a result, there are no known side effects or health issues associated with consuming dairy from cows treated with bST. IGF-1 (insulin like growth factor 1) concentrations are slightly higher in cows treated with bST. However, the human body synthesizes IGF-I and drinking 1.5 L of milk is equivalent to an estimated 0.09% of the IGF-I produced by adults each day (5, 6, 7, 8).

USDA organic dairy products are “produced without antibiotics fed or administered to the animal at any point in its life” (9). There are no meaningful nutrition differences between organic and conventional dairy products. I covered that topic in this post.

What are the Cows Eating?

Cows’ diets also vary depending on many of the same factors that influence your food choices. However, unlike humans, all cows have the benefit of seeing a nutrition expert (like dietitians, animal nutrition experts are specialists). Many consumers also have questions about how cows are fed. Cows are fed nutritious diet to ensure health of cow and nutrition of milk. Typical feed mixtures may include haylage (grass with a higher water content), corn silage, sugar beet pulp and a protein mineral mix.

Rest assured, your dairy products are safe. In fact, the dairy product that says it is made with cows not treated with antibiotics is the exact same as the one from a cow that may have been treated with antibiotics. Both contain no antibiotic residues. Growth hormones used in dairy also pose no known threat to human health. The human body does not even recognize the main hormone used in cows. So, regardless of what milk, yogurt, or cheese you choose, all have been produced and extensively tested to ensure they are safe for human consumption.
