Mexico’s Agriculture Department says its tests found no salmonella in Mexican tomatoes.

It says Mexican officials took samples from the same soil, water and tomatoes recently examined by U.S. inspectors and found no evidence of the bacteria.

A team of inspectors from the U.S. Food and Drug Administration visited five Mexican farms in search of the source of a salmonella outbreak that has sickened more than 1,000 people.

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

Mexico’s Agriculture Department said in a statement released Friday that the U.S. should clear Mexican tomatoes from any suspicion.
