According to media reports, on December 18 a radio station and a newspaper in the state of Ticino received packages containing cans of meat distributed by two different stores and a letter with the following message written in block letters: "Se vi piace la carne mangiatevi questa. Abbiamo avvelenato diversi campioni di carne in Ticino" ("If you like eating meat. We have poisoned several samples of meat in Ticino.") The letters were signed by the Animal Rights Militia.

As a precaution, stores have removed products by the two companies from their shelves.
