Episode summary
Protecting Consumers from Foodborne Cyclospora Parasite | Bloomberg Businessweek
Summary
Food-safety worries centered on a cyclospora outbreak traced by US regulators to shredded iceberg lettuce from a particular supplier, with the host noting that affected restaurant stocks moved lower. Dr. William Schaffner said investigators appear close to the end of the outbreak because the CDC and state health officials have implicated that lettuce source, though he said the full story is not completely settled.
Schaffner said consumers should still be careful with produce: wash it thoroughly, brush it off if possible, and remember the rule to wash it, peel it, or cook it. He explained that outbreaks can spread widely now because national food distribution can turn one contaminated item into infections across many states, unlike more localized outbreaks decades ago.
On severity, Schaffner said the large outbreak justified caution, especially for older people, pregnant women, the frail, and the immunocompromised. He also addressed New York City’s Legionnaires’ cases, saying the bacteria likely came from poorly maintained cooling towers, where spray from building systems can carry infection. He said the health department has been aggressive and believes that outbreak is now at an end.
Key takeaways
- Dr. William Schaffner said the cyclospora outbreak appears to be ending after investigators linked it to shredded iceberg lettuce from a particular supplier and farm in Mexico.
- Schaffner said produce should still be washed thoroughly, and the safest approach remains to wash it, peel it, or cook it.
- He said modern national food distribution can make a single contaminated item produce a far larger outbreak than in the 1930s, 40s, and 50s.
- Schaffner said the large outbreak especially matters for older, frail, pregnant, and immunocompromised people.
- For New York City’s Legionnaires’ cases, Schaffner pointed to cooling towers as the likely source and said the health department has been very vigorous in response.
