Laboratory testing by the U.S. Food and Drug Administration has confirmed that both a sample of serrano pepper and a sample of irrigation water collected by agency investigators on a farm in the state of Tamaulipas, Mexico (business address is in Nuevo Leon, Mexico) contain Salmonella Saintpaul with the same genetic fingerprint as the strain of bacteria that is causing the current outbreak in the United States.

As a result, until further notice, the FDA is advising consumers to avoid raw serrano peppers from Mexico, in addition to raw jalapeño peppers from Mexico, and any foods that contain them.

The test results announced today are part of the FDA's continuing intensive investigation into the outbreak of Salmonella Saintpaul. The investigation has involved tracing back, through complex distribution channels, the origins of products associated with clusters of illness in the United States, as well as inspections and evaluation of farms and facilities in this country and in Mexico, and the collection and testing of environmental and product samples. One of these tracebacks led to a packing facility in Mexico, and to a particular farm, where the agency obtained the samples.

Previously, FDA inspectors collected a positive sample of jalapeño pepper from a produce-distribution center owned by Agricola Zaragosa in McAllen, Texas. The FDA continues to work on pinpointing where and how in the supply chain this first positive jalapeño pepper sample became contaminated. It originated from a different farm in Mexico than the positive samples of serrano pepper and irrigation water.

The FDA is still analyzing many of the samples taken at various farms in Mexico. If laboratory results warrant, the FDA will provide consumers with additional cautions or warnings necessary to protect their health.

On July 17, the FDA announced it had determined that fresh tomatoes now available in the domestic market are not associated with the current outbreak. As a result, the agency removed its June 7 warning against eating certain types of red raw tomatoes.

The U.S. Food and Drug Administration is advising consumers that jalapeño and Serrano peppers grown in the United States are not connected with the current Salmonella Saintpaul outbreak.

However, the FDA continues to advise consumers to avoid raw jalapeño peppers and the food that contains them if they have been grown, harvested or packed in Mexico.

In addition to domestically grown raw jalapeño peppers, commercially canned, pickled and cooked jalapeño peppers from any and all geographic locations also are not connected with the current Salmonella Saintpaul outbreak.

The FDA is working with state regulatory agencies and food industry groups that represent restaurants, grocery stores and wholesalers to ensure everyone clearly understands this new, more narrow, advisory. The FDA will continue to refine its consumer guidance as the agency’s investigation continues.

The more narrow advisory the FDA is issuing today is based on evidence gathered during a multi-week, intensive investigation conducted in partnership with the U.S. Centers for Disease Control and Prevention and public health authorities in several U.S. states to find the source of the contamination that led to the outbreak. The collective review of the current traceback investigation and harvesting dates, matched with the dates that people became ill, have combined to indicate that the contaminated jalapeño pepper originated in Mexico.

The answer to the so-called "French paradox" may be found in red wine. More specifically, it may reside in small doses of resveratrol, a natural constituent of grapes, pomegranates, red wine and other foods, according to a new study by an international team of researchers.

The researchers report that low doses of resveratrol in the diet of middle-aged mice has a widespread influence on the genetic levers of aging and may confer special protection on the heart. Specifically, the researchers found that low doses of resveratrol mimic the effects of what is known as caloric restriction - diets with 20-30 percent fewer calories than a typical diet - that in numerous studies has been shown to extend lifespan and blunt the effects of aging.

In short, a glass of wine or food or supplements that contain even small doses of resveratrol are likely to represent "a robust intervention in the retardation of cardiac aging," the authors note.

That finding may also explain the remarkable heart health of people who live in some regions of France where diets are soaked in saturated fats but the incidence of heart disease, a major cause of mortality in the United States, is low. In France, meals are traditionally complemented with a glass of red wine.

The new resveratrol study is also important because it suggests that caloric restriction, which has been widely studied in animals from spiders to humans, and resveratrol may govern the same master genetic pathways related to aging.
