In an Order of McDonald's Fries, a Human Tooth Japan unit apologizes for recent instances of contaminated food By Kate Seamons, Newser Staff Posted Jan 7, 2015 9:16 AM CST 13 comments Comments A small fries is seen at a McDonald's restaurant in Tokyo, Dec. 17, 2014. (AP Photo/Eugene Hoshiko) (Newser) – Things you don't expect to hear from McDonald's: There is no indication that a human tooth found in an order of fries was fried. That from the fast-food giant's Japan unit, which has been digging into the discovery of the tooth, which turned up in an order placed in August in Osaka. McDonald’s Holdings Co. (Japan) Ltd. further says it doesn't yet know how it ended up there: Workers at the plant that produces the fries don face masks, and none of the employees of the location in question reported an absent tooth. As the AP puts it, McDonald's Japan officials "bowed deeply" today in apology over the tooth, as well as plastic pieces that were recently found in its food. The Wall Street Journal reports that three plastic incidents were discussed. A child eating a sundae last month was lightly injured by a plastic piece determined to have come from a machine involved in assembling the dessert. The other two incidents involved plastic in chicken nuggets: One was blue, and so it could have fallen in during production (its Thai suppliers use colored materials to make it easier to sight instances of contamination), but the other was clear, a type not used at McDonald's, officials say. Reuters notes that McDonald's Japan has been obtaining its nuggets from Thai producers for less than six months, following a scandal involving a Chinese supplier that allegedly used expired meat. The company's problems stretch back further: McDonald's Japan is expected to report a sixth consecutive year of declining sales and its first loss in 11 years.
