FDA finally found the source for the Salmonella infection. As mentioned last week, they removed tomatoes from the list of possible “suspects” for spread salmonella infection. They were considering jalapenos and cilanthro.

Now they say that the irrigation water and serena pepper in a Mexican farm were the main culprit for this event. They also mentioned that since irrigation water is a cause, tomatoes cannot be ruled out as a possible carrier of salmonella.

Tomatoes had been the prime suspect in the nationwide outbreak for weeks. But last week, the FDA said only jalapeno peppers grown in Mexico were implicated in the nationwide salmonella outbreak. The FDA said then it had found the same strain of salmonella responsible for the outbreak on a single Mexican-grown jalapeno in a south Texas produce warehouse.

If it turns out the tainted irrigation water was also used on tomatoes, it could provide some of the evidence that federal authorities are looking for to back their original focus on the fruit.
