What is BPA, and why does it matter?
Historically, many canned food manufacturers, including those in the pet industry (not Zealandia), used to make their internal can linings with epoxy resin based on bisphenol A, or BPA in the production of their canned food. Every can needs a thin liner inside so that the food doesn’t corrode the metal from the inside out. The BPA was added to strengthen the plastic.
