Cyclosporiasis in Michigan: Cases declining, lettuce guidance lifted

The Michigan Department of Health and Human Services said Thursday the ongoing cyclosporiasis outbreak is slowing enough that they’ve dropped the recommendation to avoid bagged lettuce.

For context:

The worst year in the U.S. for infections was 2019, when about 4,700 illnesses were reported nationally, according to The Associated Press.

Outbreak ending?

What they're saying:

The state says new case reports are slowing, and they’ve seen a downward trend in diarrhea-related emergency department visits. 

On average, persons exposed to cyclosporiasis start to feel sick seven days after exposure, but symptoms can take up to 14 days to appear. Given the seven-day average incubation period, the health department says their data suggests:

  • Most exposures occurred in late June to early July
  • The majority of the contaminated produce is likely no longer available for consumption

Based on that, the health department says the precautionary recommendation to avoid bagged salad mixes during the outbreak is no longer in effect. 

The health department is giving the green light to resume usual food handling practices and make choices based on your individual risk tolerance.

Investigators initially narrowed in on lettuce served at Taco Bell. Federal officials subsequently said they are focused on Taylor Farms as the source.

The FDA says it is tracking five separate ongoing outbreaks.
