Oh dear Tuvok. I clearly need to explain further, To begin with, I'm not clear what you mean by "made in Fochabers". Are you talking about the processing of the beef, the beef conversion to corned beef or the canning of the finished product?
None of this really matters the context of your reply. Fray Bentos corned beef tins bear an EC Identification and Health Mark, which is a series of letters and digits in an oval shaped box. The applicable code here is: FR 65 286 002 CE. The FR means that the product is manufactured and canned in France. The 65 is the French Region code, the 286 is the Commune and the 002 is the processing plant code. The processing plant is ETS Paul Toupnot of Rue Mirabel, Lourdes.
The use of these codes is a legal requirement by the EC and the manufacturer and/or canner have to provide a traceable source of origin of the product. A can of corned beef "made" in Fochabers cannot under any circumstances bear a code that would indicate the product is produced at any stage in France. There are different codes applicable to UK meat products and if the corned beef was truly made in Fochabers, it would not bear a French Code. In fact, EC food regulations allow the closure of any facilities that assert their products are made elsewhere.
