Bisphenol A: incidental non-ingredient
For petfood, the issue is its use in the epoxy resin that lines the inside of cans
[" On a global scale, BPA is produced in significant quantities, exceeding 60 million pounds annually. ", "BPA functions as a â€œplasticizerâ€\u009D added to make plastics more resilient and pliable."] In the production of petfoodsâ€”no different than human foodsâ€”there are a number of compounds that make their way into the food that arenâ€™t a part of the formula/recipe or stated on the ingredient listing. This is nothing underhanded or disingenuous, merely a function of the process, package and regulations. These compounds are often called â€œprocessing aidsâ€ because they make production of the food more effective. They appear in minute incidental quantities and do not impart any value to the foodExamples include things like carriers, flow aids and release agents. Other compounds in food may come from agents used in food contact surfaces such as detergents and biocides used in sanitation, gases used to flush oxygen from packages or barrier films impregnated with antioxidants to improve shelf-life.In some cases, compounds used to produce the packaging itself can end up in the food. One such packaging compound that periodically lands in the newspapersâ€™ health section headlines is bisphenol A (BPA). While most of these incidental compounds are quite safe, for BPA there is evidence that it may leach from the plastic packaging material into the food or drink and then impact health if exposure levels are excessive. The primary area of concern has surrounded bottles used for infant formula and soft drinks. Is there any cause for concern in petfoods?Bisphenol A was ...
