MOST OUTBREAKS OF FOOD POISONING ARE TRACED to contaminated meat. Federal investigators have now identified another potential culprit: fresh apple cider, the kind sold at roadside stands or refrigerated in plastic jugs. Tracking a 1991 Massachusetts outbreak of infection with dangerous E. coli bacteria, researchers discovered that most of the 23 victims drank unpasteurized, unpreserved cider purchased at a local farm stand. Scientists warn that some small cider mills do not carefully wash and scrub their apples, which may have dropped to the ground and been tainted with animal droppings. The drink had been thought safe because of its acidity...
...known for decades that cows given booster shots of BGH would produce more milk -- up to 15% more. But the only available source of the hormone was the pituitary glands of butchered cows, which yield only minute quantities. Then, in 1982, scientists used new gene-splicing techniques to manipulate bacteria into mass-producing BGH. By the mid-1980s, four drug companies -- including Monsanto and Eli Lilly -- had applied to the FDA for permission to market the product...
TOOTH FILLINGS HAVE BEEN ACCUSED OF EVERYTHING from picking up radio transmissions to causing learning disabilities. Now comes another charge that could stick: fillings may be partly to blame for the growing problem of antibiotic-resistant bacteria...
...real villain is the mercury that makes up about 50% of dental amalgam. In a study reported in the journal Antimicrobial Agents and Chemotherapy, monkeys with mercury fillings showed a jump in drug-resistant bacteria from 9% to 70%; when the fillings were removed, resistance dropped to 12%. It seems the genes that protect bacteria from mercury lie close to those that protect against antibiotics, so bugs that survive one tend to survive the other...
