Reactions from GM-fed Meat & Animal Products

Spending two days curled up on the bathroom floor violently ill was not what I expected from eating a pork chop from a pig fed genetically modified (GM) feed. If I were the only one, this blog wouldn’t be necessary.

I am one of the lucky canaries in the coalmine, very sensitive to toxicity, who react quickly and severely. Many others also react from GM-food and GM-fed animal products (dairy, eggs, and meat), often with delayed health issues, which makes it very challenging to figure out what to attribute it to. So many people react that it is a common practice today for functional medicine doctors to prescribe a non-GMO diet to their patients. There are many stories of healing and reversal of diseases from those eating foods that are organic, non-GMO, and pasture-raised animal products.

The question is why? Why are many people reacting from GM-fed animal products?

In the fall of 2014 I moved from the DC-suburbs to a farm in the Blue Ridge mountains of Virginia. The plan was to raise my own meat, but in the meantime, I needed food. I have Celiac and am extremely sensitive to toxicity. I had been on an autoimmune protocol (AIP) for a couple of years at that time and was doing great. As a regenerative agriculture professional, I heartily embrace AIP’s stance on eating healthy pasture-raised meats fed a non-GM diet. The community I moved to has a large population of holistic people, and I was excited to find a lot of beyond organic food straight from farms. Being very busy with the move, I hadn’t yet done much research and bought some pork from a farmer who I had thought said he fed a non-GM diet to his pigs. I cooked up the pork chops for my family and was loving mine. I was half way through it when I had stabbing pains in my stomach. Then came the nausea; I was violently ill for two days.

I used to mourn that I am one of the canaries in the coal mine, reacting so strongly to GMOs and toxicity. Now I realize it is a blessing. My family had no outward immediate reactions from the pork as I did, but that doesn’t mean it didn’t do damage. I did go back to the farmer and found out that yes, indeed, he fed his pigs GM-feed. My previous pig farmer up in Northern Virginia feeds his pasture-raised pigs non-GM feed and I have no trouble with his pork, chickens, or turkeys. For my livestock, I decided to use a non-soy organic feed as I believe it is a cleaner healthier source of nourishment for them and ultimately me and my girls.

I looked for research to help explain why many get ill from GM-fed animal products, and here is what I found. Back in the 1990s the Director for the Center for Veterinary Medicine (CVM) at the US Department of Health and Human Services, Gerald B. Guest, questioned the safety of GM crops with regards to livestock and said the following: “…CVM believes that animal feeds derived from genetically modified plants present unique animal and food safety concerns. … Residues of plant constituents or toxicants in meat and milk products may pose human food safety problems.”

Dr. Jack Heinemann, professor in genetics and molecular biology at the University of Canterbury in New Zealand, states in his report on animals exposed to GM ingredients in animal feed: “There is substantial and credible literature that reports the detection of DNA and protein unique to GM in plants within animals and animal products.” In his summary, after reviewing extensive research, Heinemann says there is “… no reasonable uncertainty that GM plant material can transfer to animals exposed to GM feed in their diets or environment, and that there can be a residual difference in animals or animal-products as a result of exposure to GM feed”. What the difference is was not stated and is likely unknown at this time.

A Danish pig farmer, Ib Pedersen, found deformity, sickness, deaths, and poor productivity with GM feed. He observed symptoms of bloat, stomach ulcers, and high rates of diarrhea go away within days of switching his pigs to a non-GM diet. Dr. Monika Kruger of the Institute of Bacteriology and Mycology, Faculty of Veterinary Medicine at Leipzig University in Germany tested some of Pedersen’s deformed piglets and found “Glyphosate residues in different organs and tissues as lungs, liver, kidney, brain, gut wall and heart of malformed euthanized one-day-old Danish piglets….”

Why worry about glyphosate? Glyphosate is the main ingredient in Roundup which is the world’s most used herbicide sprayed liberally on GM crops, also called Roundup Ready crops. Roundup is also commonly used as a desiccant to dry out conventionally grown crops before harvest. This is a common practice in wheat. A report by Earth Open Source states, “Far from being benign, Roundup has been linked in laboratory and epidemiological studies and clinical reports to serious health effects, including endocrine disruption, DNA damage, birth defects, cancer, and neurological disorders. Some toxic effects have been found at low doses comparable to those found in food and feed crops and drinking water.” In 2015, the World Health Organization classified glyphosate as a probable carcinogen.

Dr. Judy Carman, in Australia, did a study with pigs feeding GM feed to one group and non-GM feed to another and found statistically significant, 2.6 times, moderate and severe stomach inflammation in the GM-fed pigs. She states “One explanation for the inflammation results could lie with the Cry 3Bb1 and Cry 1Ab proteins that these GM corn varieties are engineered to produce. They act as insecticides by inducing pore formation and disintegration of the gut tissue (Spok et al., 2007) of certain grubs that attack corn plants. It has been argued that these proteins cannot harm the gastrointestinal tract of mammals because mammals lack the necessary gut environment and receptors (ANZFA, 2000). However, Vazquez-Padron et al. (2000) found six proteins in the mouse small intestine that could bind to a Cry protein (Cry 1Ac). Furthermore, when the Cry protein bound to these proteins, it resulted in hyperpolarisation of the intestine, which is consistent with the formation of cationic channels, as occurs in the insect gut (Vazquez-Padron et al., 2000).”

The conclusion of the Carman study was “Pigs fed a GMO diet exhibited heavier uteri and a higher rate of severe stomach inflammation than pigs fed a comparable non-GMO diet. Given the widespread use of GMO feed for livestock as well as humans this is a cause for concern. … Humans have a similar gastrointestinal tract to pigs, and these GM crops are widely consumed by people, particularly in the USA, so it would be prudent to determine if the findings of this study are applicable to humans.”

Glyphosate or GM proteins?

Is it the glyphosate in the animal products causing many to be sick, or is it toxic GM proteins causing damage to our digestive systems, or both? I am not sure, and the many scientists, veterinarians, functional medicine providers, and farmers I’ve asked also aren’t sure. So, yes, I agree whole heartedly with Dr. Judy Carman that at a minimum it is prudent to do long-term studies; and while we await the findings, avoid GM foods including GM-fed animal products: meat, eggs, and dairy.

As to the health concerns of GMOs, Chris Kresser, a nationally-known functional medicine provider, states “In genetically modified corn and cotton, a gene from a bacteria called Bt (Bacillus thuringiensis) is inserted, which causes a pesticidal toxin to be produced in every cell of the plant. This Bt-toxin kills insects that eat the plant by breaking down its gut lining and killing the insect from septicemia caused by the ensuing blood infection. (7) While this toxin has not been proven to be toxic in this way for humans and other mammals, several recent studies have suggested this toxin could have effects on immune health, gut health, liver and kidney function, and fertility.”

Take this prudent advice from one of the canaries in the coal mine and eat organic and pasture-raised meats and other animal products. “The gut is most susceptible to the potential dangers of GMO consumption. Bt toxin produced by GMO corn has been shown to significantly alter immune function in mice, and may cause disrupted immune function in the gut. (8, 9, 10) One study suggested that Bt toxin has toxic effects on human cells in vitro, causing them to die prematurely. (11) This could cause damage to gut endothelial cells if the toxicity is found to occur in vivo. The potential intestinal effects of GMO consumption go beyond Bt toxin. Some argue that gut bacteria are capable of acquiring DNA sequences from GM plants, which could lead to the development of antibiotic resistance in those microbes. (12) It’s not yet fully understood what proportion of the GM genes are able to be transferred to gut microbiota.”

There are so many reasons not to eat GM-foods, including the broken promises of GMOs; and your health is at the top. We all have great power with our purchasing choices. For health reasons, I raise my own livestock and what I don’t raise myself I buy from other farmers who raise pasture-raised non-GM or organically fed livestock. It is all about the ingredients! What the animals eat creates the level of nutrition (or toxicity) that we will get in their meat, eggs, and dairy. Just as healthy soil creates more nutrient-dense produce, a healthy non-GM and organic diet for livestock gives us healthy animal products.
