SRMs cannot be used in which of the following?

• A. Human foods
• B. Animal feeds
• C. Fertilizers
• D. Pharmaceuticals

Answer: (B)

SRMs are specific tissues from cattle that carry a high risk of transmitting prion diseases like BSE. Because these prions are extraordinarily difficult to destroy and can persist through processing, there is a strict ban on using SRMs in feeds fed to animals. Feeding SRMs to animals could introduce prions into the herd and propagate disease, so the regulation focuses on preventing their inclusion in animal feeds. While SRMs are also restricted in human foods to protect consumers, the question targets where they are prohibited within the feed system, making animal feeds the correct choice.
