CDC has never compared E. coli risks of organic, > traditional food

Contrary to a well-circulated article written by Dennis T. Avery, the federal Centers for Disease Control and Prevention (CDC) has never conducted a study that compares the risk of contracting E.coli bacteria in both conventional and organically grown food. Avery is the Director of Global Food Issues at the Hudson Institute, which is "a research organization dedicated to thinking about the future from a contrarian point of view," according to its literature.

Avery published an article entitled "The Hidden Dangers in Organic Food" in the Fall, 1998, issue of American Outlook, a quarterly publication published by the Hudson Institute. Avery's article began, "According to recent data compiled by the U.S. Centers for Disease Control (CDC), people who eat organic and 'natural' foods are eight times as likely as the rest of the population to be attacked by a deadly new strain of E. coli bacteria (0157:H7)."

A statement from Dr. Mitchell Cohen of the CDC last month states that: "Since 1982, most of the outbreaks of Escherichia coli 0157:H7 have been associated with foods of bovine origin (e.g. - ground beef). In recent years, a wider spectrum of foods, including produce, have been recognized as causes of outbreaks. The Centers for Disease Control and Prevention (CDC) has not conducted any study that compares or quantitates the specific risk for infection with Escherichia coli 0157:H7 and eating either conventionally grown or organic/natural foods. CDC recommends that growers practice safe and hygienic methods for producing food products, and that consumers, likewise, practice food safety within their homes (e.g., thoroughly washing fruits and vegetables). These recommendations apply to both conventionally grown and organic foods."

Sharon Hoskins of the CDC told Alternative Agriculture News that the CDC did not have any such research currently in the works, nor was it planning to conduct any in the future because such research was "not warranted." "We are not planning any research on organic and natural foods," she said. She also said, "We have tried to contact the magazine and have never been able to speak with anyone at American Outlook, including the editor. There has been no response."

Avery's article has been excerpted in several other publications, including The Wall Street Journal, whose excerpt included these sentences from the American Outlook article: "Consumers of organic foods are also more likely to be attacked by a relatively new, more virulent strain of the infamous salmonella bacteria. Salmonella was America's biggest food borne death risk until the new E. coli 0157 came along. Organic food is more dangerous than conventionally grown produce because organic farmers use manure as the major source of fertilizer for their food crops. Animal manure is the biggest reservoir of these nasty bacteria that are afflicting and killing so many people. Organic farmers compound the contamination problem through their reluctance to use antimicrobial preservatives, chemical washes, pasteurization, or even chlorinated water to rid their products of dangerous bacteria."

No documented research sources were given to support these assertions. The Organic Trade Association has also disputed Avery's article, reporting that, "According to Robert Tauxe, M.D., chief of the food borne and diarrheal diseases branch of the CDC, there is no such data on organic food production in existence at their centers....Let the record show that manure use is a common agricultural practice for conventional and organic food production....Any organic grower that uses the certified organic label must abide by safe food production standards, and, as with all food producers, must be in compliance with their local and state health standards."
