Tests set for Mexican food imports

WASHINGTON (CNN) - The federal Food and Drug Administration says it's going to test some foods from Mexico for salmonella before they enter the U.S. market as part of the agency's investigation into the recent salmonella outbreak.

Starting Monday, FDA inspectors will expand the salmonella probe beyond tomatoes to include cilantro, jalapeno and serrano peppers, scallions and onions. The samples will be taken to warehouses where they will be subjected to testing.

"If (the sample) tests negative, it's open to release" into the marketplace, David Acheson, FDA's associate commissioner for food protection, told CNN on Saturday. "The amount of testing is unlikely to have a significant impact to the flow of products into the U.S."
