May 16 (Reuters) - The U.S. Food and Drug Administration said on Wednesday the harvest season for romaine lettuce, linked to the multi-state E. coli outbreak, was over and it was unlikely that it was still available in stores due to its 21-day shelf life.
The reported strain of E. coli, which produces poisonous substances known as Shiga toxins, can cause severe abdominal cramps, bloody diarrhea and vomiting.
The Centers for Disease Control and Prevention said on May 2 one person from California had died related to the E. coli outbreak.
The last shipments of romaine lettuce from Yuma, Arizona were harvested on April 16, according to the FDA. (bit.ly/2GT7v6b)
