It just came to my attention that at least 3 offices of the Rabbanut's Kashrut program have announced that there is a serious problem with infestation in certain frozen fish in Israel.
The fish is called "Bakla Tza'ir" and is one of the absolute cheapest fish you can buy in this country - so I'm sure there are frugalistas and frugalites out there who buy it regularly.
They are warning that the infestation with worms is pervasive, and they have told service providers that are under their kashrut that they cannot use this fish for the time being.
That's all I know!
I will not be buying this fish for now (I have definitely bought it in the past, when in search of affordable fish!), so I thought I'd just share the info here, so everyone can make their own decisions about what to do!
