Michigan environmental news: parasite cases triple in a week

DETROIT. A cyclosporiasis outbreak has spread across 21 counties in Michigan since infections began June 22, concentrated in Monroe, Washtenaw, Wayne, Livingston, Shiawassee, Lenawee and Jackson counties. Confirmed cases went from 174 on Tuesday to 228 on Wednesday to more than 300 on Thursday, six times the state's typical yearly total. Health officials haven't found a source and are telling residents to wash and refrigerate produce.

Near record heat is straining DTE Energy's grid, and outages have hit neighborhoods in Warren. DTE says the outages come from demand, not intentional brownouts, and says grid upgrades are underway.

In better news, Detroit's Rogell Park opened on the city's west side after more than a decade of work turning a 98 acre former private golf course into a nature preserve. The chemical cleanup is done, and the site now has trails, wetlands, meadows, boardwalks and overlooks. Community input pushed the design toward passive, nature-focused space over active recreation; more amenities are planned as funding allows.
