Police are seeking a woman who they say urinated on potatoes at a Walmart in western Pennsylvania.
West Mifflin police posted surveillance photos on their Twitter account. It is not known when the incident took place.
A Walmart representative told local news outlets an employee saw what the woman was doing.
In a statement, Walmart told WPIX "it immediately disposed of the affected products and sanitized the area."
Walmart says it is working with police to find the person and have her prosecuted.
The incident comes weeks after video posted on social media showed people licking ice cream from freezers at Walmarts in Texas and Louisiana.
