Health officials have declared an end to a multi-state E. coli. outbreak linked to romaine lettuce that hospitalized 25 people last year.
Sixty-two people were sickened by the outbreak between October and December last year. No deaths were reported but two people developed a type of kidney failure from eating the contaminated lettuce. Illnesses were also reported in Canada as well.
Industry to Step Up Safety
Recently, there have been repeated food poisoning outbreaks linked to romaine lettuce in the United States, prompting the produce industry to look into its safety measures to prevent, catch, and contain contamination.A contested aspect of the regulation, for example, would require testing irrigation water for E. coli. The FDA put the measure on hold when the produce industry said such tests wouldn’t necessarily help prevent outbreaks.
In the earlier 2018 outbreak, the bacteria was traced to romaine from Yuma, Arizona where testing of generic E. coli. in the water already occurs. The produce industry says the failure to prevent the Yuma outbreak could reflect the limitations of testing water for generic E. coli.
Elizabeth Binh, a food science expert at Cornell University, said the tests look for the amount of fecal matter in water. She said the problem is “some feces has pathogens in it, some feces doesn’t.” Binh is part of a federal program helping farmers comply with the new produce regulations.
The food science expert added that testing for specific E. coli strains that are harmful is more difficult, and it doesn’t rule out the possibility of other harmful bacteria.
Additional regulations on sanitation for workers and equipment—other potential sources of contamination—only recently started being implemented.
The labels will identify the origin of the romaine lettuce based on harvest region, along with the date of harvest. The agency said this would help to limit the amount of product to be removed from the market and it will help consumers, restaurants, and retailers determine that the romaine lettuce they are buying is from an unaffected growing region.
