Is Lettuce Safe to Eat Again?

Cyclospora outbreak slows down, experts say lettuce consumption is now safe.

1Outbreak Slowing Down

Over 22,000 cyclospora cases and 517 hospitalizations were reported across 15 US states, with two deaths in Michigan. However, experts indicate the outbreak is slowing and lettuce consumption is now safe. Most contaminated products have been removed from the market. Taylor Farms initiated a recall on July 17, advising consumers to discard products with 'best by' dates through August 3.

2Source and Distribution

Federal health authorities linked the outbreak to iceberg lettuce sourced from central Mexico and distributed by Taylor Farms, including at Taco Bell restaurants. The recall significantly reduced the risk. Kali Kniel from the University of Delaware states that lettuce consumption is now safer.

3Other Risks

While cyclospora risk has decreased, consumers should remain cautious. As of August 6, two new clusters in North Carolina involving parsley and cilantro are under investigation. A separate salmonella outbreak tied to jalapeños has infected 345 people across 27 states. Taylor Fresh Foods recalled jalapeño-containing products.

4Incubation Period and Cases

Cyclospora has an average incubation period of 7 days, extending up to 14 days. Due to the mid-July recall, most exposures likely occurred in June and early July. New cases may still emerge if contaminated products were consumed at home, but expiration dates have passed, reducing the risk.

5Situation in Michigan

Michigan, hardest hit by the outbreak, reported over 12,000 cases since June, compared to the usual 40-50 annual cases. New cases have declined since late July. On August 6, the state health department lifted the advisory against bagged salad mixes, allowing normal food practices to resume.

6Precautions and Advice

On July 13, Michigan identified lettuce and salad greens as potential sources, advising consumers to buy whole lettuce, discard outer leaves, and wash inner leaves thoroughly. Cyclospora clings to surfaces and resists common sanitizers, making it hard to eliminate.

7Complexity of Food Systems

Joseph Eisenberg from the University of Michigan highlights how complex food systems increase foodborne illness risks. Bagged salad mixes contain produce from multiple farms, complicating traceability. Whole lettuce is a safer choice due to simpler supply chains.

8Climate and Future Risks

Brian Schaneberg from the Illinois Institute of Technology notes that drought and global warming elevate cyclospora risks. Contaminated irrigation water can spread the parasite. Summer peaks foodborne illnesses, requiring continued consumer vigilance with fresh produce.
