The outbreak’s source remains a mystery. Food and Drug Administration investigators have spent the past week inspecting farms in parts of Florida and Mexico and the warehouses and other stops those farms’ tomatoes made on the way to market.
The government continues to urge consumers nationwide to avoid raw red plum, red Roma or red round tomatoes unless they were grown in specific states or countries that FDA has cleared of suspicion. Check FDA’s Web site — http://www.fda.gov — for an updated list. Also safe are grape tomatoes, cherry tomatoes and tomatoes sold with the vine still attached.
