MSNBC reported yesterday that a study done by the journal Environmental Health shows detectable mercury in nine out of 20 samples of high fructose corn syrup made in the United States.
Dr. David Wallinga, a food safety researcher and activist at the nonprofit Institute for Agriculture and Trade Policy tested 55 different foods where high fructose corn syrup was the first or second ingredient on the label. Fifty five different foods included jam, barbecue sauce, jam, chocolate syrup, and yogurt. One out of three had mercury above the detection limit.
It is believed that the mercury got into the food during manufacture, at plants that use mercury-grade caustic soda produced in industrial chlorine plants. The Corn Refiners Association has challenged the findings.
Certain fish has been found to contain high levels of mercury. Even low levels of mercury have been shown to harm the developing brain. To see which fish have low levels of mercury, click here and here.
