Parasite Cases Increasing In MA: See Latest Data, Products To Avoid

Case numbers of cyclosporiasis continue to steadily increase in Massachusetts as officials work to contain the multi-state outbreak of the diarrhea-causing parasite.

The CDC says that Massachusetts has between 50 and 199 laboratory confirmed cases. The Massachusetts Department of Health has confirmed 147 cases.

Nationally, case counts have risen to more than 22,000, according to the CDC, with 10,468 confirmed cases and another 12,255 additional probable or under-investigation cases. Thousands more have been reported by state health departments.

Some states like Illinois have seen a decrease in new cases, even as the total case numbers continue to increase.

The investigation into the source of the outbreak remains ongoing.

The recall on iceberg lettuce from Taylor Farms in Mexico remains in place, despite a false positive on a test earlier this week. Traceback data from cases connects this outbreak to that source, the CDC said.

Taco Bell has since removed the affected lettuce from its local restaurants and national supply chain, and Taylor Farms has issued a nationwide recall of iceberg lettuce sourced from Mexico. Sysco, the nation’s largest food distributor, withdrew all Taylor Farms iceberg lettuce from Mexico at ​the supplier's request.
