A University of Minnesota-licensed manufacturer released test results earlier this month in response to allegations of one of their products containing potentially dangerous levels of arsenic.

Michigan-based environmental nonprofit Ecology Center claimed a University-branded key ring was found to contain high levels of arsenic back in March.

Wincraft Inc., the manufacturer of the key ring and other college and professional sports fan gear, sent the product to a third party testing lab after Wincraft’s own test results showed no levels of arsenic in the product. The new test results indicate that the key ring contains less than 2 parts per million of arsenic, far lower than the 246 parts per million claimed in the Ecology Center’s tests.

The Environmental Protection Agency requires arsenic levels in drinking water to be below 0.01 parts per million. While guidelines have been set to limit arsenic in drinking water, children’s products and cosmetics, state and federal agencies have set no limits for consumer products such as the University key ring.
