Fish unfit for human food, whether parasitic or not, which are offered for sale for animal food must be denatured or identified so as to prohibit their use for human food. Denaturing must be accomplished either by cutting the fish in two immediately behind the abdominal cavity or by dyeing the fish with methyl violet. The strength of the dye solution used may not be less than one part of dye to 5,000 parts of water.
