Michigan State's Norman Hord challenges health standards that treat nitrates and nitrites in food as harmful, arguing that as they occur in plants they may benefit cardiovascular health. Between 70 and 80 percent of nitrates in most diets come from vegetables.

Safe Handling of Raw Produce and Fresh-Squeezed Fruit and Vegetable Juices
FDA guidance on handling raw produce and fresh-squeezed juices: bacteria in soil or water can contaminate fruit and vegetables before harvest or during preparation and storage, and the document offers buying, washing and storage tips to cut the risk of foodborne illness.

Is bottled water healthier?
The Environmental Working Group says fewer than 2 percent of bottlers disclose their water's source, purification and pollutants, and a congressional report found the FDA has little authority over the industry. The NRDC says a quarter of bottled water starts as tap water.

E. coli found in Nestle cookie dough
The FDA said it found E. coli O157:H7 in a sample of prepackaged Nestle Toll House refrigerated cookie dough from the Danville, Va. plant, but had not determined whether that strain caused the outbreak, which had sickened 69 people in 29 states and hospitalized 34.

Beef recall and E. coli poisoning
JBS Swift has expanded its June 24 recall to 380,000 pounds of beef primal products over possible E. coli O157:H7, up from 41,280 pounds. A spokesman said no illnesses were reported; a food safety attorney cites a CDC inquiry into 24 illnesses, at least 18 apparently linked.

Picnic food safety greater concern in hot weather (PR)
Texas AgriLife Extension's Rebecca Dittmar warns that heat speeds growth of bacteria you cannot see, smell or taste, and that picnic foods get handled a lot. Her guidelines are clean, separate, cook and chill: wash hands and surfaces, pack sanitizer, and keep raw meat away from produce.

Studies: BPA may cause heart problems in women
Scott Belcher of the University of Cincinnati exposed rat and mouse heart cells to BPA or estrogen and saw abnormal activity, including more frequent arrhythmias, in female cells but not male ones. Other work presented at ENDO 09 found more BPA in the urine of people with cardiovascular disease.
Chemical
BPA hazards ringing alarm bells
The FDA has still issued no verdict on BPA in food containers, a spokeswoman said, even as cities, states and countries ban it and studies link it to cancers, diabetes and heart disease. Regulators in the U.S., Canada, Europe and Japan call current exposure no immediate risk.
Chemical
Arsenic in well water higher than thought
A US Geological Survey sampling of 2,100 private wells in 48 states found more than 20 percent held at least one contaminant of potential health concern, most often radon or arsenic. Private wells supply about 43 million Americans and are not federally regulated.
Chemical
Hexane ignites soy controversy
An investigation by Cornucopia and Natural News reports that soybeans are bathed in hexane, a volatile gasoline by-product, during processing, leaving residues never tested for toxicity. Two processing plant hexane accidents injured 11 people and killed two workers.

Tips to avoid BPA exposure
Fetuses and babies take the most intense BPA doses, and tests have found BPA leaching from metal cans into every brand of liquid formula, so EWG recommends powdered formula where a baby tolerates it. Adults should avoid canned foods and skip polycarbonate plastic for warm food and drinks.
Chemical
Fluoride fuss alive and well
CDC ranks water fluoridation among the 20th century's top 10 public health achievements, while the Fluoride Action Network and more than 2,000 signatories call EPA's 4 parts per million standard unsafe, citing a 2006 National Research Council review of possible adverse effects.

MSG: Its history, effects and what you can do to avoid it.
MSG, identified by Kikunae Ikeda in 1908 and declared generally recognized as safe in 1959, stimulates the umami receptor; the FDA calls “MSG Symptom Complex” a short-term reaction causing headaches and nausea. The editor notes toxicity depends on dose and that glutamic acid occurs in all protein.

Food Dye linked to ADHD
Nineteen toxicologists, pediatricians and other professionals asked Congress to ban certain synthetic dyes, citing a 2007 UK Food Standards Agency study that found they exacerbate some hyperactive behaviors and European labeling rules that warn parents.
Chemical
Congress calls for federal ban on BPA
Proposed legislation would ban BPA in food and beverage containers for adults as well as children under three, after Sunoco told investors it would not sell BPA for such uses. Studies cited link BPA to developmental problems in lab animals and, in humans, to heart disease and diabetes.

Artificial food dyes linked to hyperactivity, doctors urge Congress to act
Nineteen psychiatrists, toxicologists and pediatricians have asked Congress to ban synthetic food dyes, pointing to a growing link with hyperactivity and attention problems. Dyes such as Red 40, Yellow 5 and Blue 1 are common in gum, candy and cereal marketed to children.

Food poisoning cases in 2008
CDC's FoodNet surveillance in 10 states found that 2008 incidence of Campylobacter, Salmonella, Listeria, E. coli O157 and other enteric infections did not change significantly from the preceding three years, and none of the Healthy People 2010 reduction targets were met.

Cancer-causing toxins detected in fluoride chemicals
CDC data show arsenic in 43 percent of 245 water fluoridation chemical samples taken from 2000 to 2006, copper in 3 percent, lead in 2 percent, and barium, chromium, mercury, selenium or thallium in under 1 percent. The EPA sets its arsenic goal for water at zero.
