The Food and Drug Administration (FDA) today announced that it has moved closer to identifying the source of illness for the Taco John E. coli outbreak. FDA and the state of California, working in conjunction with state health officials in Minnesota, Iowa, and Wisconsin, have DNA-matched the strain of E. coli O157:H7 bacteria associated with the outbreak with two environmental samples gathered from dairy farms near a lettuce growing area in California's Central Valley.
The investigation is ongoing, including obtaining additional samples, to determine if and how material from the dairy farms may have contaminated the lettuce growing area.

In the wake of recent outbreaks of consumer illness connected with fresh produce, FDA will accelerate its efforts to address produce safety, including consideration of new regulations, if appropriate, to reduce risk of contamination by pathogens.
In the near future, the FDA plans to announce public meetings specifically to involve all stakeholders in identifying and initiating measures that will improve the safety of fresh produce marketed in U.S. commerce.
