Hy-Vee investigates data breach

Iowa-based Hy-Vee is investigating a possible security breach involving its payment processing systems. In a release, the grocery chain says it recently detected unauthorized activity and immediately launched an investigation focusing on transactions at its fuel pumps, drive-thru coffee shops, and restaurants, including its Market Grille locations.

The company does not believe the breach affects cards swiped at its front-end grocery checkout lanes, pharmacies, customer service counters, wine and spirits locations, floral departments, clinics and food service areas, or those processed through Aisles Online.

Hy-Vee has three Wisconsin locations, all of which are in Dane County — two in Madison and one in Fitchburg.
