Several people have been hospitalized after drinking meth-laced 7Up in Mexico, reports The Washington Post.
Authorities are warning travelers of the revelation, which has been discovered in the Mexicali area, just south of the California border. Health experts are asking people to be extra cautious as to whether or not seals on food and drinks are tampered with.
"If you notice any difference in color, taste or smell, throw it out," medical director at the Banner Poison and Drug Information Center in Phoenix Daniel Brooks said.
Officials have opened an investigation into the contaminated products in Mexico, and have assured American consumers that 7Up products in the U.S. have not been affected.
"None of the 7Up products sold in the U.S. are affected by the issue being reported in Mexico," Chris Barnes, a spokesman for Dr. Pepper Snapple Group, said. "Dr. Pepper Snapple owns and licenses the 7Up brand only in the U.S. and its territories. We do not market, sell or distribute the brand internationally."
