Another salmonella positive found by FDA in serrano peppers

WASHINGTON - The Food and Drug Administration has found its "smoking gun" and - in a key breakthrough - has apparently found the source of the salmonella poisoning outbreak in the United States during the last three months.

The FDA has traced the salmonella strain to irrigation water used by a grower in Tamaulipas, Mexico, and to a sample from a batch of serrano peppers at a packing facility in Nuevo Leon, Mexico.
