The U.S. Food and Drug Administration has advised consumers that tomatoes are safe to eat again, after the agency linked the food product to an outbreak of salmonella.

The FDA lifted its tomato warning Thursday, saying it no longer believes that tainted tomatoes are entering the U.S. market.

About 1,200 people have suffered salmonella poisoning in recent weeks, in one of the largest outbreaks in the U.S. in recent years.

U.S. authorities are still investigating other food products suspected of contributing to the outbreak, such as hot peppers. Investigators have been searching farms in the southeastern state of Florida and in Mexico for the source of the contamination, but have yet to find it.
