Ask the Rabbi

STAR-K CERTIFICATIONrealizes that there is no substitute for a person's own Rav. However, in today's busy and connected world many people have difficulty getting in touch with their Rabbanim when they are needed. In an effort to offer a solution to this challenge, STAR-K launched its Institute of Halachah as a public service. Over the years, the agency's Kashrus Hotline has answered more and more halachic questions beyond the scope of Kashrus information, from consumers the world over, beyond the standard steady stream of inquiries regarding the kosher status of foods and certified Sabbath mode appliances which has made the STAR-K Kosher Hotline famous. The formation of a separate official division within STAR-K testifies to the need for addressing these issues.

The Institute of Halachah is directed by HaRav Mordechai Frankel, under the guidance of HaRav Moshe Heinemann, STAR-K's Rabbinic Administrator. It is an invaluable resource for a diverse array of rabbis to discuss general halachic matters, as well as gain access to source materials for shiurim and answers to congregants' questions.

Shailos may emailed using the form below, or called into the Institute of Halacha at 410-484-4110 x238. Rabbi Frankel or on occasion another STAR-K Rabbi will respond to your email or return your call if you leave a message and phone number.

  • Halacha Questions

  • Am I allowed to work as the anesthetist for a non-frum Jewish veterinarian who does sterilizations of cats and dogs? I live in Israel, so if I don’t do it the replacement anesthetist would probably be Jewish anyway.
  • Halacha Questions

  • Regarding a women’s obligation of tzniyus in the presence of men, is there any difference between whether the man is Jewish or non-Jewish? It is understandable that we don’t want to encourage Jewish men to look if they are not allowed, but this isn’t one of the ‘sheva mitzvos bnei noach’ and should not apply to non-Jewish men.
  • Halacha Questions

  • I bought Eggland's Best eggs, and each egg shell is stamped with a red inked "EB" within a circle. Can I cook these in a pot to make hard-boiled eggs? The ink will definitely come off and cook in the pot. Is the ink kosher?
  • Halacha Questions

  • If a non-Jew intentionally adds a non-kosher ingredient to kosher food, and the non-kosher ingredient is bottel be’shishim, is the food permitted?
