Pine Nuts Reportedly Leave Some People with “Pine Mouth” Aftertaste

Pine nuts imported from China have reportedly left some Americans with a bitter, metallic aftertaste, prompting the Food and Drug Administration (FDA) to investigate the claims. According to a news source, FDA has received about two dozen complaints of “pine mouth” in recent months, but no illnesses have been reported. “Should the FDA find a public health hazard, then we will advise consumers accordingly,” an agency press officer said.

The United States reportedly imports some 25 million pounds of pine nuts annually, 90 percent of which comes from China. A Richmond, Virginia, importer of Chinese pine nuts has scoffed at the pine mouth phenomenon, calling it an “Internet sensation” on food websites and blogs. He said he first heard reports of pine mouth a few years ago and had his product tested for heavy metals, Salmonella, yeast, and mold, but that testing revealed nothing unusual.
