Animal Products and Animal By-Products:
Meat, milk, egg, poultry, and their products, including products made with these materials, such as dried soup mix or bouillon, are either prohibited or restricted from entering the United
States, depending on the types of animal diseases which occur in the country of origin. Fresh (chilled or frozen), dried, cured, and fully cooked meat is generally prohibited from most countries. Canned meat is allowed entry, except beef, veal, lamb, mutton, venison, elk, bison, etc., from countries affected by bovine spongiform encephalopathy (BSE).
Products containing raw egg ingredients are prohibited from most regions.
Eggs and egg products from Exotic Newcastle Disease (END) and Highly Pathogenic Avian Influenza (HPAI) affected regions, including cooked eggs, if not accompanied by a USDA Veterinary Service import permit remain prohibited regardless if those items are for personal consumption. There is no exception for cooked eggs from Mexican
states of Sonora or Sinaloa.
Pork should be commercially canned and labeled in unopened containers. Pork and pork products are not admissible from
Mexico, except for cooked pork in small amounts for a meal.
Effective January 14, 2010, cooked pork skins (also known as pork rind) entering as commercial cargo or in passenger baggage from regions affected with foot-and-mouth disease (FMD), swine vesicular disease (SVD), African swine fever (ASF), or classical swine fever (CSF) must be accompanied by an original certificate issued by an official of the National Government of the region of origin.
Comme le foie gras en boîte correspond à une canned meat à partir de volaille (dans le paragraphe ce sont les produits carnés en boîte faits à partir de boeuf, mouton et gibier qui sont prohibés pour risque de vache folle) ça ne paraît pas directement interdit, mais à déclarer sous peine de 100$ d'amende et je suppose que si le douanier décide que ce jour là ça ne passe pas vous ne pourrez pas faire grand chose. Par contre présenté autrement qu'en boîte de conserve je pense que ça ne passe probablement pas
