BETHEL, Alaska—
Sled dogs eating a salmon diet have higher levels of mercury than of those eating commercial diets.
Those are of the findings of study conducted by an environmental group and published in Environmental Research Letters.
KYUK reports (http://bit.ly/trWLzx) mercury is believed to offset the benefits of omega-3 fatty acids associated with salmon. Dogs were found to have lower levels of antiodixidants.
However, the study finds that dogs - and people – should continue to eat a subsistence diet since benefits are greater than the small levels of mercury.
The study examined dogs along the Yukon River.
