Final answer:
The correct term for items removed from animals due to BSE regulations is 'prohibited materials.' For legislation that makes it illegal to bring certain parrot species to the U.S. for sale, the answer is 'CITES' (Convention on International Trade in Endangered Species of Wild Fauna and Flora).
Step-by-step explanation:
The term used to describe items removed from the animal because of BSE regulations is prohibited materials. These regulations are crucial for preventing the spread of Bovine Spongiform Encephalopathy (BSE), which can have severe implications for cattle health and can potentially impact human health if transmitted. The rules are enforced to ensure that potentially infectious parts of cattle, such as the brain and spinal cord, are handled with caution and not entered into the food chain or used in products destined for human or animal consumption.
Relating to the legislation that prohibits the importation of certain species of parrots to the United States to be sold as pets, the correct answer is CITES, which stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora. This international agreement aims to ensure that international trade in specimens of wild animals and plants does not threaten their survival.
