Hot Off the Hotline

Amongst the number of recent eye opening events that have impacted the Jewish community, a discovery was made last May regarding the halachic status of New York tap water. The New York kosher consumer was shaken by the fact that New York tap water, which had the reputation of being one of the most pure, clean, and natural water available, contains unwelcome visitors called copepods that are visible to the human eye. In spite of that fact that this was a New York discovery, the Star-K hotline in Baltimore was abuzz with inquiries of “Can we drink the water?!” This is the Star-K response regarding copepods in drinking water based on discussions with Rav Moshe Heinemann Shlit”a, Star-K Rabbinical Administrator.

Q: What are copepods?


A: Copepods, also known as “insects of the sea,” are crustaceans that are found wherever water is […]

Star-K’s New Kashrus Training Program A Huge Success

August 2004

How can you learn to deal with the challenges of supervising a first-class hotel’s kosher kitchen which is next to its non-kosher kitchen? Where does one find the opportunity to tour a flavor plant to better understand the kosher manufacturing process? Who will train you to find the less obvious thrips and aphids when checking a restaurant’s vegetables? What will give you the preparation to administer – or perhaps, pioneer – a communal kosher certification agency?

Star-K Kosher Certification recently provided the platform for these unique learning opportunities and more. In its new complimentary certificate program, Star-K’s Kashrus Training Program allowed Kollel yungerleit of Yeshivas Ner Yisrael to experience the field of kosher supervision first hand. Held July 12-16, at Star-K’s offices in Baltimore, Maryland, the five day intensive seminar was limited to 25 students who have studied Yorah Deah.

When You Need to Knead: A Guide to Hafrashas Challah

Kashrus Kurrents Fall 2004 | Updated June 2024

One of the many ways Klal Yisroel serves the Ribbono Shel Olam is through the performance of mitzvos hateluyos ba’aretz, mitzvos that are dependent on the Land of Israel. Those who live in Israel have many opportunities to fulfill these mitzvos. In chutz la’aretz, the mitzvah of hafrashas challah is one of the only agricultural mitzvos that we are obligated to perform.1

It is well known that this is one of the mitzvos performed preferentially by women. Furthermore, one honors the Shabbos by baking and being mafrish challah on Erev Shabbos.2

The following are halachic guidelines based on the psak of Rabbi Moshe Heinemann shlit”a.3

Sabbath Mode and Sabbath Compliant Appliances

Updated January 2023

Appliance manufacturers, with the aid of modern technology, have designed kitchen appliances to be safer and more efficient while incorporating various features to enhance operation. However, the integration of this technology may pose a challenge to their proper use on Shabbos and Yom Tov.

THE INTRODUCTION OF SABBATH MODE

In 1997, a historic technological project was launched between a major appliance manufacturer and a kosher certification agency. Whirlpool Corporation (manufacturer of KitchenAid) approached STAR-K to help modify their ovens for use on Shabbos and Yom Tov. Prior to that time, many of their appliances did not conform to halachic guidelines.

Following some adjustments, a successful mode was developed. Whirlpool called this “Sabbath Mode” and was awarded a patent in 1998 for this concept.

STAR-K kosher certification on appliances falls into one of two categories:

1. Sabbath Mode Appliances – these are models that have unique software/hardware specifically […]
