A study showing a possible link of hyperthyroidism in cats (FH) to polybromated diphenyl ethers (PBDEs) was released by the American Chemical Society on August 15, 2007. Some of the sources for contamination by this chemical are from fire retardants used in fabrics such as those on mattresses, carpets and furniture. Canned cat foods are another source.
I presume, though it was not stated, that the route of it into the cat food is mainly from fish, as other information has shown that fish off the coast of CA have higher than average levels of PBDEs. Other animals also have this chemical, though not at comparable levels.
Humans are also being exposed to some of these same sources for PBDEs. Some well known examples are former President and Mrs. George H.W. Bush, who developed this disorder. Their dog, Millie, also was affected.
And as the article stated, “…hyperthyroid cats could serve as modern-day versions of the canaries in the cage that alerted coal miners to poisonous gas.”
Dr. Janice A. Dye and colleagues from Indiana University and the University of Georgia conducted this research.
