DNA Testing of Caviar for Species Identification
Testing with AFT can also benefit caviar suppliers. Only roe from kosher fish is kosher. Unlike skin-on fillets, unless the roe is cut out of a kosher fish in front of the rabbi, there is no other means of identifying the roe as kosher without AFT. AFT can test caviar using the same method used to test kosher fish. Thus, customers following a kosher diet can purchase AFT-tested caviar and be assured they are eating roe from a kosher fish.
