Hiermit dürfte bzgl. Fleisch alles gesagt sein:
"USDA does not allow travelers to bring back most cattle, swine, sheep or goat meat or meat products from countries affected with certain serious livestock diseases:
Foot-and-mouth disease
Bovine spongiform encephalopathy (BSE)
Swine vesicular disease
Classical swine fever
African swine fever
To find out a country’s status for these diseases, visit our animal disease status page.
Commercially-packaged and labelled, cooked, shelf-stable meat items in unopened packages from affected countries are allowed, with one exception. Sheep and goat meat/products cannot enter from BSE-affected countries. View a list of these countries.
Travelers may not bring back more than 50 pounds of an item. Shipments larger than 50 pounds are considered commercial shipments and must meet additional requirements through USDA’s Food Safety and Inspection Service. Contact them at (202) 720-9904 or
www.fsis.usda.gov.
Travelers may bring back fresh (chilled or frozen), cooked, cured or dried meat from countries without these diseases if they have official documentation to prove the product’s country of origin. The following items are considered official documentation: package label; written documentation; proof of travel (passport or travel itinerary); origin of flight; receipt of sale; CBP document (based on the officer’s interview of the traveler); a meat inspection certificate; or certificate of origin.
Cured hams (prosciutto, Serrano ham, Iberian ham) and salami from areas within France, Germany, Italy and Spain may not be brought into the United States by travelers. These items may only enter in commercial shipments because there are special restrictions that require additional certification and documentation."
