FDA Considers Additive to Detox Pig Feed from Sneaky Zearalenone

Published Date: 9/3/2025

Proposed Rule

Summary

Biomin GmbH asked the FDA to approve a new food additive that helps break down a harmful toxin called zearalenone in pig feed. This change aims to keep pigs healthier by reducing this toxin safely. If approved, farmers could start using this additive soon, making pig food safer without extra costs.

Analyzed Economic Effects

3 provisions identified: 3 benefits, 0 costs, 0 mixed.

Proposal to Allow Enzyme in Swine Feed

The FDA received a petition to allow the enzyme zearalenone hydrolase to be added to swine feed at no less than 10 U/kg of complete feed (U = the five-fold enzymatic activity that hydrolyzes 1 µmol zearalenone per minute in a solution of 5 mg/L zearalenone). If approved, feed makers and pig farmers could legally use this enzyme in pig feed at that specified dose.

Reduces Harmful Zearalenone in Pigs

The petition says the additive helps break down the harmful toxin zearalenone in pig feed and aims to keep pigs healthier by reducing that toxin safely. This change is intended to improve animal health on farms by lowering zearalenone exposure in swine.

No Extra Feed Cost If Approved

The document states that if approved, farmers could start using the additive soon and that it would make pig feed safer without extra costs. That means, according to the petition summary, farmers would not face added feed costs when adopting the enzyme.
