Repeat outbreaks pressure produce industry to step up safety

NEW YORK >> After repeated food poisoning outbreaks linked to romaine lettuce, the produce industry is confronting the failure of its own safety measures in preventing contaminations.

The E. coli outbreak announced just before Thanksgiving follows one in the spring that sickened more than 200 people and killed five, and another last year that sickened 25 and killed one. No deaths have been reported in the latest outbreak, but the dozens of illnesses highlight the challenge of eliminating risk for vegetables grown in open fields and eaten raw, the role of nearby cattle operations that produce huge volumes of manure and the delay of stricter federal food safety regulations.

A contested aspect of the regulation, for example, would require testing irrigation water for E. coli. The Food and Drug Administration put the measure on hold when the produce industry said such tests wouldn’t necessarily help prevent outbreaks. Additional regulations on sanitation for workers and equipment — other potential sources of contamination — only recently started being implemented.

FDA Commissioner Scott Gottlieb said he thinks the combination of rules, once fully in place, will make vegetables safer to eat.

“I don’t think any one element of this is going to be the magic bullet,” Gottlieb said.

Health officials say improved detection may make outbreaks seem more frequent. Still, that is intensifying pressure on growers and regulators to prevent, catch and contain contamination. plant leaves with chlorine to kill potential contaminants, Suslow said. But he said such treatment raises concerns about soil and human health.

Meanwhile, the proximity of produce fields to cattle operations is likely to continue posing a problem. Travis Forgues of the milk producer Organic Valley noted consolidation in the dairy industry is leading to bigger livestock operations that produce massive volumes of manure. doesn’t,” said Bihn, who is part of a federal program helping farmers comply with the new produce regulations.

Testing for specific E. coli strains that are harmful is more difficult, and it doesn’t rule out the possibility of other harmful bacteria, Bihn said.
