Salmonella found in pepper farm in Mexico, FDA says

They matched the strain that has sickened more than 1,300 people across the US and Canada.

The bacteria were reportedly found in irrigation water and a Serrano pepper. Previously, the FDA traced a contaminated jalapeno pepper to a farm in another part of Mexico.

The investigation originally focused on tomatoes. US officials insist tomatoes still can't be ruled out, and say it is possible the outbreak was caused by several different kinds of contaminated produce.

Mexican officials have repeatedly denied a Mexican farm is responsible for the outbreak.
