Rabbi Nissan Zibell of Kashrus: Be in the Know answers many practical questions that arise for the kosher consumer in an upcoming series. 

Fish is one of our staple foods. Whether on the Shabbos table, while eating out, or served as a basic supper meal. Fish is also accessible in so many places. That’s why as a kosher consumer, getting the fish facts straight can help you navigate buying fish in any supermarket!

Ever wonder:

Is any fish with fins and scales kosher?

Can I buy any Tilapia fillets?

Kashrus: Be In The Know is an organization that has been helping to educate consumers for over three years now.

The best way to keep kosher at home is by learning the halachos that one needs to know. And then there is shopping in the supermarket…

Kashrus: Be In The Know was created with the intention to increase Kashrus awareness and provide consumers with a knowledge of basic halacha, as well as important information regarding how foods are made and processed. With this information, it is their hope to help people in making educated choices when buying products.

Although the classes are given by Rabbis who both work in respectable hashgachos, and have a depth of knowledge in Halacha as well as the food industry, it does not in any way replace asking questions to a Rav. Rather, it presents the awareness to even know what to ask.

To date, there are over 1,800 people receiving weekly and informative classes on their WhatsApp Groups.
