FDA, under enforcement discretion, had previously not objected to the use of hydrogen peroxide to control fungi on all species and life stages of fish, including eggs.
However, hydrogen peroxide is now the subject of an FDA-approved new animal drug application with the trade name 35%PEROX-AID www.fda.gov/cvm/CVM_Updates/perox-aid.htm. Therefore, the only approved hydrogen peroxide product that can be used in fish production is 35%PEROX-AID. There is no longer any enforcement discretion for the use of hydrogen peroxide to control fungi on all species and life stages of fish, including eggs, or for its use to treat any other fish disease.
Aquaculture producers raising fish for human food consumption should not use drug compounds other than the approved product because it can be unsafe for your fish. In addition, the effectiveness of unapproved drug compounds is questionable.
The FDA is also reminding food animal producers to read veterinary drug labels carefully and follow label directions to help avoid causing illegal residues in their products.
