Minnesota deer hunters are being asked by the Department of Natural Resources to be on the lookout for methamphetamine lab activity, KSTP-TV reports.
The request comes as the DNR notes the increase of meth labs on public lands, including state parks, state forests and wildlife management areas.
The DNR says signs of a meth lab include large quantities of common household products.
"Used as designed, these household products are generally safe," the DNR says. "Mixed together, they can become explosive and/or give off toxic fumes."
The DNR has posted a list of chemicals and equipment that hunters, hikers and other outdoor enthusiasts should look for.
Earlier this week, a man in southeastern Minnesota was burned in an explosion involving a suspected meth lab, the Star Tribune reports.
The Houston County Sheriff's Department says the man, 50, suffered severe burns in the explosion and was taken to a burn center for treatment.
