US Federal food officials have matched a bacterial strain found on fresh jalapenos in a Texas distribution plant to the strain responsible for what has become the nation’s largest food-borne outbreak in the past decade.
The strain found on the jalapenos, Salmonella Saintpaul, was a genetic match to the strain found in lab tests of many of the 1,251 people who have become sick from salmonella poisoning over the past three months.
It was the first time officials had found the strain on fresh produce. But the discovery still does not tell investigators whether the contamination occurred in Mexico, where the peppers were grown, or at the distribution center in McAllen, Texas. The contamination might also have occurred somewhere in between, David Acheson of the Food and Drug Administration (FDA) said on Monday in a conference call with reporters.
The agency is warning consumers not to eat fresh jalapeno peppers or foods containing them. The small-scale distribution plant, Agricola Zaragoza, initiated a recall of jalapenos, Acheson said, the associate commissioner of foods for the agency. But it is unlikely that the recall will account for all contaminated produce on the market because the McAllen distribution network was so small.
Robert Tauxe of the federal Centers for Disease Control and Prevention said the salmonella outbreak, which hospitalized at least 229 people, was continuing.
“We are still getting new cases reported, and do not believe that it has ended at this point,” he said. On Thursday, the FDA lifted its six-week warning to consumers to avoid certain raw tomatoes, which had been linked to the outbreak after initial epidemiological studies. Michael Hansen, senior scientist for Consumers Union, said the agency did “the precautionary thing” by warning consumers not to eat those tomatoes.
Several other experts in food safety said the lag in finding the source of the contamination reflected the government and the industry’s weak ability to track the source of problems in the nation’s food supply.
“The recent situation shows that we have deficiencies in the system,” Michael Doyle said, the director of the Center for Food Safety at the University of Georgia. “My experience with the industry is that in part, certain segments of the industry would rather not have food trace-back.”
David Kessler, an FDA commissioner in the 1990s, said that “the agency needs to put the industry on notice that it has to develop a full trace-back system by a specific date.”
