The number 385 on the tin's stamp tells us it comes from cattle company JBS.
Food manufacturer Princes are 'big in corned beef' - that food cupboard staple with a use-by date sometime in the next millennia. In 2007, they were the third largest canned food supplier to the UK.
We've come across Prince's in the past because they sell a lot of canned tuna, but they also sell a lot of corned beef. With all of the Amazon cattle work we've been doing lately we've developed a keen interest in where they get it from, and tins of Princes corned beef are rapidly multiplying around the forest campaign team's office space.
