DETROIT — Michigan's worst outbreak of cyclosporiasis has slowed, with fewer than 200 new cases reported this week, according to numbers released Thursday by the state.

The Department of Health and Human Services indicates 142 new cases of the parasitic illness were reported this week, down from 283 cases reported last week and the lowest since 71 cases were reported the week of June 21. The total number of cases reported in Michigan since late June rose to 14,510.

"The data, including a downward trend in diarrhea-related emergency department visits, suggests that new cyclosporiasis case reports are continuing to slow," health department spokesperson Laina Stebbins said in an email.

"We additionally believe that the majority of the contaminated produce is likely no longer available for consumption," she added.

Michigan officials issued guidance earlier this month that residents can resume eating lettuce and salad greens, the likely source of the outbreak with cases and hospitalizations on the decline.

The department said, on average, people exposed to cyclosporiasis start to feel sick seven days after exposure, but symptoms can take up to 14 days to appear. The department said the data suggests the majority of the contaminated produce likely is no longer available and most exposures occurred in late June to early July.

Cases of cyclosporiasis have been recorded in 72 of Michigan's 83 counties, with the most cases reported in Wayne County (2,581 cases), Oakland County (1,599 cases), Washtenaw County (1,114 cases) and Ingham County (925 cases).

As of Thursday, 356 people had been hospitalized, according to the health department.

Two Michigan residents with cyclosporiasis have died in the outbreak. The health department declined to give many specifics about the deaths, including in which county they occurred, but said the deceased had "significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration."

Both of the individuals who died fell ill before the Taylor Farms de Mexico voluntary recall on July 17, according to the U.S. Food and Drug Administration.

Michigan is one of 15 states included in the outbreak, but has reported more cases than any other state.
