Matt Jones was in a Subway restaurant in Portland, Oregon, and said spotting the mouse in a sandwich was the funniest - and most disgusting - thing that he had ever seen. And he wasn’t the only one. Jones told a local TV station that his friend wanted spinach on his sub and when the employee scraped some from a bin and put it on the bread, there was shock all round.

A Lincoln County health inspector studied the rodent, the bin and the restaurant for further signs of rodent activity but it was found that the culprit most likely arrived in a bag of spinach.

Subway has declined to give details regarding its spinach supplier but has stated that the restaurant was thoroughly cleaned and the customer given a refund.
