Recent Trends and Past Cyclospora Outbreaks in Michigan
Cyclospora outbreaks are relatively rare but have occurred in Michigan and other states in recent years, often linked to imported fresh produce. The last notable outbreak in Michigan was reported in 2018, involving dozens of cases traced back to contaminated berries. Public health agencies have since increased monitoring of produce imports and emphasized consumer education on proper food handling. The current investigation follows a pattern of sporadic cases that can escalate if not swiftly contained.
“We are actively investigating confirmed cases of cyclospora and working with partners to identify the source. Residents should remain vigilant and practice good hygiene.”
