On March 13, the U.S. Food and Drug Administration (FDA) announced a new regulation that permits the use of benzoic acid as a feed additive in pig feed and drinking water. This decision becomes effective immediately upon publication. The public is invited to submit written comments or request a hearing by April 14, 2014. Here are the key details of the rule:
First, benzoic acid can be used as an acidifier in animal feed to lower the pH. However, its concentration in the total feed should not exceed 0.5%. This ensures safe and controlled application while maintaining the health of the animals.
Second, the additive must contain at least 99.5% benzoic acid (CAS No. 65-85-0). Any impurities, such as 2-methylbiphenyl, 3-methylbiphenyl, 4-methylbiphenyl, benzyl benzoate, and other isomers, should not exceed 0.01% by weight. Additionally, the total amount of dimethylbiphenyl should also remain below this threshold. These specifications ensure the purity and safety of the product.
Third, to ensure proper and safe usage, labels must include the following information:
1. The name of the additive.
2. Clear instructions for use, emphasizing that benzoic acid must be evenly distributed and thoroughly mixed into the entire feed. All swine feed containing benzoic acid must be clearly labeled.
3. Appropriate warnings and safety precautions related to handling and exposure.
4. A warning stating that benzoic acid may cause irritation.
5. Information on emergency assistance in case of accidental exposure.
6. Contact details, including the address and phone number for reporting adverse reactions or requesting a Material Safety Data Sheet (MSDS).
This regulation aims to provide a safer and more effective way to use benzoic acid in animal feed, ensuring both the well-being of livestock and compliance with federal standards. The FDA continues to monitor the impact of such additives to maintain high levels of food safety and quality.
