According to phys.org, researchers at the University of Missouri have found that short-term feeding of canned dog food has resulted in a significant increase of BPA in dogs. Scientists believe that because of shared environments, dog exposure to BPA through canned foods could have human health implications.
Bisphenol A (BPA) is a widely used industrial chemical found in many household items, including resins used to line metal storage containers, such as food cans.
“The dogs in the study did have minimal circulating BPA in their blood when it was drawn for the baseline,” Rosenfeld said. “However, BPA increased nearly three-fold after being on the either of the two canned diets for two weeks. We also found that increased serum BPA concentrations were correlated with gut microbiome and metabolic changes in the dogs analyzed. Increased BPA may also reduce one bacterium that has the ability to metabolize BPA and related environmental chemicals.”
Dogs who share internal and external environments with their owners are likely excellent indicators of the effects of BPA and other industrial chemicals on human health.
“We share our homes with our dogs,” Rosenfeld said. “Thus, these findings could have implications and relevance to humans. Indeed, our canine companions may be the best bio-sentinels for human health concerns.”
