The companies threatened included Italian coffee companies Lavazza and Caffe Vergnano  and Nutella producer Ferrero, The Associated Press reported Wednesday, citing northern Italian investigators. 

Danish Crown, a meat producer, was also threatened, although the company said its employees and customers were not at risk, according to the AP.
