We're Eating What? Contaminants in Meat, Part 1

The Hidden Meat Contaminants You Might Be Eating

Recently, the U.S. Department of Agriculture announced plans to "relax" federal meat and poultry inspections, allowing meat processors greater leeway in policing themselves, already the agricultural trend. But most food activists ask how standards could be relaxed any further when drug residues, heavy metals, cleaning supplies, gasses, nitrites, hormones and other unwanted guests contaminate the meat supply. They are almost all unlabeled.

Is seafood safer? Dream on. Mercury-filled tuna is what inspired Fischer Stevens to make the Oscar-winning documentary "The Cove," about the Japanese dolphin-fishing industry, when he personally came down with mercury poisoning. The Chicago Tribune, New York Times and Consumer Reports have reported high mercury levels in almost all red lean and fatty tuna tested in recent years. Aquaculture is so festooned with antibiotics, veterinary drugs and pesticides, it can make factory farming look, well, green. Commercial shrimp production, for example, "begins with urea, superphosphate, and diesel, then progresses to the use of piscicides (fish-killing chemicals like chlorine and rotenone), pesticides and antibiotics (including some that are banned in the U.S.), and ends by treating the shrimp with sodium tripolyphosphate (a suspected neurotoxicant), Borax, and occasionally caustic soda," says a review of Bottomfeeder : How to Eat Ethically in a World of Vanishing Seafood on AlterNet.

Meat contaminants are not likely to go away because they stem from Big Meat's desire to maximize profits by growing animals faster, squeezing them into small living spaces and keeping meat looking "fresh" on store shelves longer. Here is a list of worst offenders:

Antibiotics

Most people know that antibiotics are part of the diet of U.S. livestock to make them grow faster (feed is metabolized more efficiently) and prevent disease outbreaks in cramped conditions. But they'd be surprised at how many animals destined for the dinner table have drug residues that exceed legal limits. Each week the USDA's Food Safety and Inspection Service (FSIS) finds dangerous antibiotic levels in animals that include penicillin, neomycin and "sulfa" and "cipro" drugs, many from "repeat violators." Excessive levels are also found of risky antibiotics like tilmicosin, whose label tells the farmer, "Not for human use. Injection of this drug in humans has been associated with fatalities" (nice!) and gentamicin, which the FDA, American Veterinary Medical Association (AVMA) and Association of Bovine Practitioners warn against using at all, except under rare circumstances. Unlike bacteria which antibiotics are supposed to kill, "No amount of cooking will destroy [drug] residues" says a USDA Office of the Inspector General report.

Bacteria

You'd think with the antibiotic party going on, meat would be free of bacteria. You'd be wrong. Bacteria are rife in conventionally grown U.S. meat including antibiotic-resistant bacteria also known as superbugs. Almost half of beef, chicken, pork and turkey in samples tested from U.S. grocery stores contained staph bacteria, reported the Los Angeles Times in 2011 -- including the resistant MRSA staph bacterium (methicillin-resistant S. aureus). Pork tested by Consumer Reports in 2013 also contained MRSA and four other kinds of resistant bacteria. Two serious strains of antibiotic resistant salmonella, called Salmonella Heidelberg and Salmonella Hadar, forced recent recalls of turkey products from Jennie-O Turkey and Cargill and chicken products from Schreiber Processing Corporation.

The resistant salmonella strains were so deadly, officials warned that disposed meat should be in sealed garbage cans to protect wild animals. Yes, even wildlife is threatened by the factory farm-created scourges. MRSA is no longer limited to health care settings, either. Researchers have found it on Florida public beaches and on the top of unopened soft drink can in a car that was following a poultry truck.

Cleaning Products, Yes Cleaning Products

As antibiotics are no longer doing the job, meat producers are getting spooky creative. They are trying radiation, gasses, nitrites and even sprays made of viruses called bacteriophages to quell the germfest. Still, nothing has caused such reflexive revulsion as the news last year that meat scraps once earmarked for pet food were being resurrected as "lean finely textured beef" (LFTB), also called Pink Slime. While the product looked like human intestines, what really turned the national stomach was that it was treated with puffs of ammonia to kill the bacterium E. coli. The public was also outraged that the pink slime was supplying the National School Lunch Program. Its main producer, Beef Products, Inc., announced it was closing its production facilities soon after the hoopla began. But there is another cleaning product used in meat production that is starting to make news: chlorine. According to the website MeatPoultry.com, "99 percent of American poultry processors" cool their "birds by immersion in chlorinated water-chiller baths." Who knew? The European Union and Russia are currently duking it out with U.S. trade officials over the chlorine-dipped poultry that few Americans realize they are eating.

Hormones

There is another product Americans eat every day that the European Union doesn't want: beef. The European Commission's Scientific Committee on Veterinary Measures says the U.S.'s hormone-heavy beef production poses "increased risks of breast cancer and prostate cancer," citing cancer rates in countries that do and don't eat U.S. beef. Like the "fine print" in lean finely textured beef, Americans are blissfully unaware of the synthetic hormones zeranol, trenbolone acetate and melengestrol acetate that are part of the recipe for production of U.S. beef. Melengestrol acetate, which is not withdrawn in the days before slaughter, is 30 times more active than natural progesterone, says the European Commission. The powerful estrogenic chemical Zeranol is associated with early puberty and breast cancers, charges the Breast Cancer Fund, a group dedicated to identifying and eliminating the "environmental causes" of cancer. "Consumption of beef derived from Zeranol-implanted cattle may be a risk factor for breast cancer," agrees a recent article in the journal Anticancer Research . And trenbolone acetate, a synthetic androgen? It is on scientists' radar because it masculinizes fish . Too bad USDA is not as cautious as the European Commission.

Mad Cow Disease

Many people have forgotten about Mad Cow Disease, but the risks are far from gone, especially because the government has obfuscated. In its final report about the first U.S. mad cow, found in December 2003, the government said "all potentially-infectious product" from the deadly cow "was disposed of in a landfill in accordance with Federal, State and local regulations." But the San Francisco Chronicle reported that 11 restaurants received the meat. Big difference. The sources of the Mad Cow Disease seen in a second and third cow were never found but the government protected the identities of the Texas and Alabama ranches and let them sell beef again within a month. Mad Cow and related diseases like Chronic Wasting Disease in deer are transmitted by prions which are "rogue proteins" that are not destroyed by cooking, heat, autoclaves, ammonia, bleach, hydrogen peroxide, alcohol, phenol, lye, formaldehyde, or radiation, and they remain in the soil, contaminating it for years. Because Mad Cow Disease could destroy the U.S. beef industry, officials are quick to dismiss possible human cases. When suspicious cases arise, officials call them "spontaneous" illnesses, not from eating bad meat -- even before tests are in.
