I have brought in chilled cheeses, cooked packaged pork (BBQ Pork, Carnitas, hot links, salami, and ham). I’ve brought in packaged, raw bacon a few times. Got a couple packs of smoked salmon to eat with my deli bagels and cream cheese, in May.
Some countries won’t let you bring in meat of any sort. I recall a visit to Seoul many years ago, that I declared my packaged beef jerky, and had to give it up. The US is very strict, too.
