A small rubber fragment was found in a chicken nugget at a McDonald's outlet in Okayama Prefecture last October, a public relations official of McDonald's Holdings Co. (Japan) revealed Saturday.
The fragment was reported by a female customer at a McDonald's in Tsuyama on Oct. 31, and was later confirmed to be from the glove of a worker in a Thai factory, the public relations official said.
McDonald's Japan apologized to the customer Thursday, according to the official.
