Reusable plastic containers used to transport large amounts of fruits and vegetables to grocery stores can continue to harbour potentially harmful bacteria directly on their surfaces, even after undergoing industry-standard cleaning and sanitizing, according to a new study conducted by researchers from the University of Arkansas and WBA Analytical Laboratories.
The study took a microscopically close look at the materials used to make the reusable plastic containers (RPCs) that have gained a foothold in the grocery industry in recent years as a preferred method of transporting produce.
