In 2019 the National Organic Standards Board (NOSB), an advisory committee of the USDA, decided to consider the use of vaccines produced through "excluded methods" or genetic modification in organic food production. Since then, the committee advised the USDA that GE vaccines could only be permitted in organic production if an equivalent vaccine is commercially unavailable.

However, the OrganicEye, an industry watchdog, suggests otherwise. The OrganicEye said some USDA-certified organic producers are already using GE vaccines in their livestock even though it goes against the principles of organic farming. The watchdog also pointed out that consumers cannot determine whether USDA-certified organic meat, eggs or milk have been produced using GE or GMO-containing vaccines.
