San Francisco Oakland San Jose, CA, August 6, 2026 —

Michigan health officials have announced that residents can now safely resume eating lettuce and salad greens. This decision comes as a result of a notable slowdown in new cases of cyclosporiasis, a parasitic illness that can be contracted from contaminated food and water.

The advisory was put in place previously due to an increase in reported cyclosporiasis infections that were linked to the consumption of these produce items. Health authorities have been monitoring the situation closely. The recent decrease in new cases indicates that the source of contamination, or at least the period of active transmission, has significantly diminished.

Cyclosporiasis is caused by the parasite Cyclospora cayetanensis. Symptoms typically include diarrhea, loss of appetite, weight loss, cramping, bloating, and fatigue. Some individuals may also experience nausea, vomiting, and a low-grade fever. Symptoms can appear a few days to a week after infection and can last for several weeks if left untreated.

While the immediate risk associated with lettuce and salad greens has decreased, health officials continue to recommend thorough washing of all fresh fruits and vegetables before consumption as a general food safety practice. This measure helps to reduce the risk of foodborne illnesses from various pathogens.

Further details regarding the specific timeframe of the initial advisory or the exact number of cases that prompted the public health warning were not immediately available. However, the current guidance from the Michigan Department of Health and Human Services is that the consumption of lettuce and salad greens is considered safe for the general public at this time.
