"The concentrations detected are unlikely to pose a risk to healthy adult dogs," said lead author Rae Sires, a nutrition resident at the UC Davis Veterinary Medical Teaching Hospital. "These results should be reassuring to dog owners."
Excess mercury exposure is a health hazard for people and animals. Depending on the method of exposure -- such as skin contact, ingestion or inhalation -- it can lead to respiratory and gastrointestinal disease, kidney injury, impacted fetal development and neurologic issues. While previous studies have measured total mercury in commercial pet foods, additional testing for methylmercury had not been done.
Form - Bioaccumulation - Ability - Tissues - Food
"That is the form where we worry about bioaccumulation or the ability to become more concentrated in animal tissues as it moves through the food chain," Sires said. "We know there is some level of total mercury in commercial dog foods based on recent studies, but we didn't yet know whether it is cause for...
