For the purpose of safety and protection, Hostess, Inc., required their operations employees, including Sylvia Lopez, to wear steel-toed boots. One of Lopez’s boots caused a sore on one of Lopez’s legs. The skin over the sore broke, and within a week, Lopez was hospitalized with a methicillin-resistant staphylococcus aureus (MRSA) infection. She filed a worker’s compensation claim. Hostess, Inc. argued the MRSA bacteria that caused the infection had been on Lopez’s skin before she came to work. Based on the rules that cover workers’ compensation claims, how will the courts rule regarding Lopez’s claim of a work-place injury?
