Mad Cow Disease and Cosmetics

As I discuss in my video Which Intestines for Food and Cosmetics?, the Food and Drug Administration (FDA) recently reopened comments about its policy of allowing some intestines, but not others, into the U.S. food supply. When the first few cases of mad cow disease started popping up, the FDA’s gut reaction was to ban all guts from food and personal care products. Then, in 2005, the U.S. Department of Agriculture and FDA amended their draft rule to “permit the use of the entire small intestine for human food” if the last 80 uncoiled inches going to the colon is removed. Since then, however, studies have shown that infectious mad cow prions can be found throughout all parts of the intestine, from the stomach down to the cow’s colon, raising the question of whether all entrails should be removed once again from the food supply.

The North American Meat Association said no, wanting to keep cattle insides inside the food supply. Similarly, the Cosmetic, Toiletry, and Fragrance Association (CTFA, now the Personal Care Products Council) protested the concern, arguing that banning downer and dead cattle, as well as their brains, skulls, eyes, spinal cords, intestines, and tonsils, could put our nation’s supply of cosmetics in jeopardy. There could be a tallow shortage for soap, for example. The FDA may not realize that cosmetics and personal care products are a quarter trillion-dollar industry worldwide.

In the end, the FDA “tentatively” concluded that intestines should continue to be allowed in the food and cosmetic supply because “[o]nly trace amounts of infectivity have been found” throughout the bowels of cattle. The agency had to come to that conclusion because, otherwise, the meat would have to be banned as well. Indeed, new research shows there’s mad cow infectivity in the animals’ muscles, too, and not just in the atypical cases of bovine spongiform encephalopathy (BSE), like the last mad cow found in California. We now know it’s in typical BSE as well: Low levels of infectious prions have also been found in the ribs, shoulders, tenderloins, sirloin tips, and round cuts of meat.

The latest estimates from Britain suggest 15,000 people are currently incubating the human form of mad cow disease, contracted through the consumption of infected meat. Fewer than 200 Brits have died so far of variant Creutzfeldt-Jakob disease, but the incubation period for this invariably fatal neurodegenerative disease—that is, the time between eating the meat and one’s brain filling up with holes—can be decades. The fact that so many people are carrying it has important implications for the safety of blood transfusions, which is why many Americans who’ve lived in England are barred by the Red Cross from donating blood. Also at risk is the safety of handling surgical instruments that may have cut into someone who’s a carrier, as it is so difficult to sterilize anything once it’s been contaminated.

Given these factors, it may be prudent to err on the side of caution when regulating which intestines are allowed on and in our mouths, but it’s a balance. As one meat company pointed out, guts are not just used for lipstick—intestines are human food, “providing us with a precious source of protein which is essential for our human population.”

Unfortunately, this is not the first time the FDA has caved to industry pressures. See, for example:

As scary as rare infections like mad cow disease are, we are much more likely to be disabled or killed by more conventional foodborne pathogens such as bacteria. Check out:

Botched Circumcision Leads to Penis Amputation for Baby Boy

From  cord blood banking  to  baby naming ceremonies , parents of newborns have a bevy of key decisions to make when it comes to medical procedures and religious and/or cultural practices. For instance, as soon as a couple learns they're having a boy, they might find themselves grappling with the  decision to circumcise—or not . It's an individual, personal decision for every family. Thankfully, when parents opt in, most circumcisions go off without a hitch. However, a shocking story out of Egypt highlights one instance in which the routine procedure went terribly awry. A father from Cairo is speaking out after his son's  penis had to be amputated following a botched circumcision . The Jerusalem Post  reported that the father named Ashraf Helmi says he took his child to Cairo to be vaccinated and was convinced by his sister-in-law and a family friend to have his  1-month-old son Mohamed circumcised during the same doctor's visit. According to  Me...

Reduce Acid-Forming Proteins to Protect Kidney Function

Chronic kidney disease is a major public health problem affecting about one in eight Americans, increasing the risks of disease and death even among those with only mild decreases in kidney function. Low-cost, low-risk preventive strategies that anyone can do are needed to address the epidemic of kidney disease. I discuss some of these in my video Protein Source: An Acid Test for Kidney Function . Diet plays a role in kidney function decline. “Specifically, diets higher in animal protein, animal fat, and cholesterol” may be associated with protein leakage into the urine, which is a sign of kidney damage, and, generally, “diets higher in fruits, vegetables, and whole grains, but lower in meat and sweets, may be protective” against kidney function decline. In comparison to the diet eaten by our ancient ancestors, not only are we eating more saturated fat, sugar, and salt, we now also eat an acid-producing diet, as opposed to a base-producing, or alkaline, diet. Ancestral human diet...
