ここにあるように　動物の病気がアメリカが気にしていることなのでオーストラリアとかとはちがいます。

Many fresh, dried, and some canned meats and meat byproducts are prohibited entry into the United States from foreign countries because of the continuing threat of foot-and-mouth disease (FMD), bovine spongiform encephalopathy (BSE, or mad cow disease), and other animal diseases. If meat from restricted countries is included as an ingredient in a product (e.g., beef broth), the product is usually prohibited.

Because regulations concerning meat and meat byproducts change frequently, travelers should contact the consulate or local agricultural office in the country of origin for up-to-date information on the disease status of that country.
