On March 13, the U.S. Food and Drug Administration (FDA) announced a new regulation allowing the use of benzoic acid as a feed additive in pig feed and drinking water. This rule became effective immediately upon its publication. Those who wish to challenge or provide feedback can submit a written request or attend a hearing by April 14, 2014. Below are the key details of the regulation:
1. Benzoic acid may be used as a feed acidifier to lower the pH of the feed. The maximum allowable concentration in whole pig feed is 0.5% of the total feed.
2. The additive must contain at least 99.5% benzoic acid (CAS No. 65-85-0). It should not contain more than 0.01% by weight of impurities such as 2-methylbiphenyl, 3-methylbiphenyl, 4-methylbiphenyl, benzyl benzoate, or dimethylbiphenyl isomers.
3. To ensure safe handling and usage, labels must include the following information:
- The name of the additive.
- Clear instructions for use, emphasizing that benzoic acid must be evenly distributed and thoroughly mixed into the feed.
- Warnings and safety precautions related to the chemical's properties.
- A statement indicating that benzoic acid can be irritating.
- Information on emergency procedures in case of accidental exposure.
- Contact details for reporting adverse reactions or requesting a Material Safety Data Sheet (MSDS).
This update reflects the FDA’s ongoing efforts to regulate feed additives while ensuring the health and safety of livestock and workers involved in animal farming. For further information, refer to the official FDA notice.
