Rubbermaid containers are not manufactured with BPA. As of 2009, Rubbermaid has manufactured their containers, bottles and other products without bisphenol A, or BPA, in response to customers' concerns about its healthfulness.
Since older Rubbermaid containers might contain BPA, consumers should check the base or side of the product for the "BPA-free" stamp. This is the only way to know for certain that a container was not manufactured with BPA.
BPA is a chemical that has historically been used to manufacture polycarbonate plastic and other products. Preliminary research has shown that the BPA used in food containers can seep into foods and beverages, potentially causing health problems, according to Mayo Clinic.
