A foodborne illness outbreak is being reported, with cases of a diarrhea-causing parasite, possibly cyclospora, rising in multiple states, including texas, michigan, new york, and illinois. The outbreak is described as large and growing, with a significant number of people affected, though the exact source is still unknown. Reports suggest the parasite may be linked to fresh produce, but there is also a separate mention of a listeria outbreak related to requesón cheese, which may or may not be connected to the parasite outbreak.
