The Vaad Hakashrus of Flatbush has been researching Anisakis infestation in the stomachs of sardines. They have been testing sardines from several countries. The following is their opinion on the matter:
At an Asifas HaRabbonim last night in Boro Park we opened many cans of sardines from Portugal and Scotland. The sardines were inspected by many Rabbonim and Kashrus experts. The sardines from Portugal were observed to be infested with Anisakis worms in the stomach and abdominal cavity, as previously confirmed by the Vaad Hakashrus of Flatbush. Additionally, the sardines from Scotland were found to be infested as well. In our opinion the necessary cleaning process is too complicated for the layman to attempt.
Therefore it is our opinion that sardines from Portugal and Scotland should not be used.
It is important to note, that the majority of sardines on the kosher market are from Morocco. Extensive research on sardines from morocco has shown them to be clean of infestation. The country of origin is printed on each package of sardines.Tzvi Shaul Goldberg
