MEXICO CITY – Mexico's health secretary says a team of health and agriculture officials has traveled to the United States to demand that Mexican tomatoes be cleared of any suspicion in a recent salmonella outbreak.

Jose Angel Cordova says the group will meet with U.S. Food and Drug Administration officials in Washington. Cordova's comments were included in an FDA statement released Monday.

A salmonella outbreak that began in April has affected more than 1,000 people in the United States. Mexico said last week that its tests found no salmonella in Mexican tomatoes.

The FDA has not released the results of tests it conducted in Mexico. It recently added peppers and cilantro to a list of foods under investigation.
