Caution Necessary During Grilling Season

Several respected sources, including Harvard Medical School and U.C. Davis Cancer Center, are linking the consumption of well-done meats to cancer. In the late 1970s, researchers discovered that cooking meats at high temperatures causes a chemical reaction between amino acids and creatine; this produces carcinogens known as heterocyclic amines, or HCAs.

Studies conducted on meats revealed that the longer the meats cooked, the higher the concentration of PhIP, a potent carcinogen which was shown to have caused prostate cancer in rats. Surprisingly, among the meats tested (chicken, steak and hamburger), chicken had by far the greatest concentration of PhIP throughout each phase of the cooking process.

To decrease the chance of consuming carcinogenic meat, there are many methods to eliminate the issue of HCAs. 95% of HCAs can be removed by partially cooking the meat in a microwave oven and discarding the juice before grilling.

By similar time and temperature consideration, the feisui process in Chinese cooking – paraboiling meat and soup bones for 5-10 minutes in boiling water and then dumping the liquid – would also reduce HCAs. It’s likely that few, if any, HCAs are formed in soup-making. If you’re really worried about carcinogens, maybe consuming soup or grilling vegetables are the best solutions.

U.C. Davis researchers recommend cooking chicken to an internal temperature between 165° F to 180° F; ground beef, pork and lamb to about 160° and 170°; and beef steaks and roasts to 145° to 160°. Their minimum recommendations fall directly in line with the USDA’s safe recommended internal temperatures found at: http://www.fsis.usda.gov/is_it_done_yet/

Follow the tips and your grilled food should be safe to eat! Have a wonderful 4th of July!
