Drug Residues in Meat

Below is an approximation of this video’s audio content. To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video.

One of the reasons we are increasingly plagued with new superbugs is the mass feeding of antibiotics to farm animals. As Britain’s chief medical officer put it in his 2009 annual report: “every inappropriate…use [of antibiotics in] agriculture is potentially signing a death warrant for a future patient.”

Earlier this year, I had the opportunity to debate some of the captains of industry, like the National Pork Producers Council, on this dangerous practice of feeding antibiotics to livestock:

“To ask if there’s a question between human drug resistance and livestock antibiotic use is like asking if there’s human-induced climate change, or if there’s a link between smoking and lung cancer. There are a few dissenting industry scientists on one side, but then basically every other scientist on the other. Both opposing camps have scientists on their side, but only one really has science on their side. One can just look at who’s on the sides of this debate. In one corner, you have the World Health Organization, the American Medical Association, the American Academy of Pediatrics, the American Public Health Association, and another 100 medical and public health organizations in the country. On the other side, you have the National Turkey Federation, the National Chicken Council, the Sheep Industry Association, the National Pork Producers. It could not be more stark…” 

I’ve always insisted that the reason it’s dangerous to feed millions of pounds of antibiotics to cows, pigs, and chickens every year—in part just to fatten them faster for slaughter—is because this fosters antibiotic resistance in bacteria that can then infect human beings—not because there’s a problem with antibiotic drug residues getting into the meat itself. How wrong I was.

In a damning report released earlier this year, the U.S. Inspector General slammed the USDA for not protecting the American public. As you can see in the Executive Summary of the report, one of the public safety issues facing the United States is the contamination of meat with residual drugs, pesticides, and heavy metals. These drug and chemical residues then find their way to our dinner plates.

But in order to safeguard the nation’s food supply from harmful residue, the USDA, FDA, and EPA are supposed to test for these contaminants, and prevent adulterated meat from entering the food supply.

But, based on their review, the Inspector General found that the National Residue Program is not accomplishing its mission of monitoring the food supply for harmful residues. They haven’t even established threshold values for many dangerous substances, which has resulted in contaminated meat being distributed to consumers. And then the USDA’s Food Safety and Inspection Service doesn’t even attempt to recall meat confirmed to have excessive drug residues.

What’s the problem with not having safety thresholds? Well, for example, in 2008, Mexican authorities rejected a shipment of U.S. beef because it contained excessive levels of copper. But since we haven’t set a safety level for copper, it was fine by U.S. standards; there weren’t any. So too dangerous to be sold in Mexico, but good enough for U.S. consumers.

There are more than a thousand pesticides approved for use in the United States. The Environmental Protection Agency routinely asks the USDA to test for pesticides that everyone agrees has high health risks. But, for many years now, they continue to test for only one type of pesticide, out of more than a thousand.

What’s the big deal, though? What potential affects could the drugs and toxic metals in meat have on people? Bleeding, ulcers, allergic reactions, serious nerve damage, severe inflammation, skin cancers, internal cancers, jaundice, kidney failure, neurotoxicity (kills brain cells), and even death.

Doesn’t cooking destroy the drugs, though? No amount of cooking will destroy residues. In fact, in some cases, heat may actually break residues down into components that are more harmful to consumers.

And then, even when our government finds these drugs in the meat, they don’t stop it from contaminating the food supply. The inspector general noted a case where a slaughterhouse found four drugs—Ivermectin, Sulfadimethozine, Florfenicol, and Sulfamethazine—yet, released the meat from these carcasses into the food supply—despite the fact that consuming these drugs could result in stomach, nerve, or skin problems. But the USDA ordered no recall.

Now, the USDA doesn’t actually have the authority to demand a recall—which is a problem in itself. But they can, at any time, ask, at least, the company to voluntarily recall the meat. So when’s the last time they asked a company to recall their meat due to illegally high drug residues? The USDA hasn’t even asked since 1979.

And this is not the first time the USDA has been cited for failing to protect the public. This was exposed 25 years ago by the National Academy of Sciences. So what happened? What happened in 1984, according to the Inspector General, is that they signed an MOU. And then, the problem remained unresolved for the next 25 years. So, that’s what we’ve been eating all this time.

So what does the Inspector General propose now? #1 recommendation: start from scratch. The government needs to reestablish the National Residue Program so it can accomplish its mission of safeguarding the U.S. food supply. What will be the USDA’s response now? Maybe they’ll draw up another memo.

In the meanwhile, if we insist on doing drugs, though our diet, which meat has been found to have the highest risk for contamination? It’s the veal. Think about how they’re raised, you know.
