Cyclospora outbreak waning, Mich. officials ease guidance on lettuce

Aug. 6 (UPI) — The cyclosporiasis outbreak in Michigan has begun to slow as health officials say people can resume taking normal precautions when consuming lettuce and salad greens.

The Michigan Department of Health and Human Services announced Thursday that Michiganders can “resume routine guidance” for lettuce and salad greens.

MDHHS has lifted its recommendation to avoid bagged salad mixes.

Michigan has been a hotspot in the cyclosporiasis outbreak, reporting 12,485 cases since June.

“Since the start of this outbreak, MDHHS has remained committed to providing timely, transparent information and clear recommendations to Michigan residents,” Dr. Natasha Bagdasarian, the agency’s chief medical executive, said in a statement. “As new data has emerged, our guidance has evolved to reflect the best available evidence, helping ensure that prevention recommendations are accurate, actionable and responsive to the changing situation.”

The department said most exposures to cyclosporiasis occurred in late June or early July. On average, people exposed to cyclosporiasis begin feeling sick about seven days after exposure but can begin observing symptoms up to 14 days after exposure.

MDHHS adds that the “majority of the contaminated produce is likely no longer available for consumption.”

Cyclosporiasis is a parasitic infection that can cause sudden, watery diarrhea, vomiting, nausea, loss of appetite and fatigue. The outbreak first spread in Michigan and Ohio before reaching a total of 15 states.

The source of the outbreak has been traced to lettuce sourced from Taylor Farms de Mexico. Its lettuce is sold in grocery stores around the United States and restaurants including Taco Bell.
