60 Minnesota E. coli Cases Linked to Potato Salad Served at Reservation Events

Published:

At least 60 people fell ill with E. coli O157:H7 in July at Minnesota’s Fond du Lac Reservation, apparently after consuming potato salad likely made with a contaminated ingredient, according to the local news outlet Pine Journal.  The infections occurred after three separate events on the reservation, all catered by the same vendor on July 11 and 16. Potato salad was served at two of those events, leading investigators to believe one of the salad’s ingredients caused the outbreak.  The first illness was reported on July 17 and the last on July 20, suggesting that the outbreak is likely over. Given that several weeks have passed since the events, the chance of determining the exact food source of the infections is growing slimmer.  Food Safety News originally reported on this outbreak on July 24, when 22 cases had been confirmed.  Four patients sickened in the outbreak have retained representation from food safety law firm Marler Clark, which underwrites Food Safety News.
