This part of ISO 23036 specifies a method that is applicable for the detection of Anisakidae L3 larvae commonly found in marine and anadromous fishes. The method can be applied to fresh fish and/or frozen fish, as well as lightly processed fish products, such as marinated, salted or cold smoked. This method allows quantifying parasitic infections by estimating the number of parasites in the fish musculature. This method doesn t allow determining species or genotype of detected parasites. Final identification is made by morphological and/or molecular methods.
