They will not tolerate any form of beef product: no matter how processed and cooked it might be. Having read on the customs site that meat which was canned and had been cooked in that can was permissible; I brought a canned steak & kidney pudding into the US. I declared it and had it confiscated.
You may not even bring in an Oxo cube. On one occasion, I brought and declared a British Christmas pudding. The ingredients were carefully scanned and they included beef suet. In the spirit of Christmas, the supervisor told the customs officer (who had intended to confiscate the pud) to turn a blind eye. Since then, we have always brought vegetarian Christmas puddings from the UK to the US. I think that the beef ban's only exception is made for one or two approved Italian salami manufacturers.
Is that an approved Italian salami in your pocket; or are you just happy to see me?
