Forse, who bought the bread from a supermarket in 2009, said Monday he first thought a dark spot in the bread — branded Best of Both — was some poorly mixed dough. Then he noticed it had fur. The case wound up in court.

Premier Foods pleaded guilty to violating health laws, and was fined 16,821 pounds ($26,470) on Friday. Forse says his gruesome discovery made him feel ill, and he felt sick again when health officers noted that the mouse’s tail was missing, perhaps already eaten in a sandwich.
