The Boston Globe is reporting that the tainted wheat gluten found in the recalled pet food has been found in plants that produce food for human consumption.

Tainted wheat gluten that triggered a massive nationwide pet food recall also ended up in processing plants that prepare food consumed by people, the Food and Drug Administration said yesterday.

Also:

According to import records, the wheat gluten was shipped to the United States from Nov. 3, 2006 to Jan. 23 of this year and contained “minimal labeling” to indicate whether it was intended for humans or animals.

Update: The FDA is now testing human foods containing wheat gluten. Also, interesting stuff over at Daily Kos.
