That comes as a very big surprise to me. I know that Israel, like many countries, bans the import of certain fresh foods (like apples) which could cause damage to the domestic agriculture but I have never heard of food, per se, being forbidden.

Whenever my girlfriend flies in from Italy (two or three times a year) she is loaded with literally kilos of parmigiana cheese and distinctly unkosher prosciutto crudo -- and has never had a bit of trouble.
