Do Bee Don’t Bee: A Halachic Guide to Honey and Bee Derivatives
Fall 2010
As we look toward the beginning of the new year, we turn our thoughts to teshuva, and the hope that our tefillos will be answered for a sweet new year. This request has been symbolized for hundreds of years on Rosh Hashana by eating challah and apples dipped in honey.1
The question regarding the kosher status of honey is older than the custom of dipping an apple on Rosh Hashana. There is a well known halacha that states that derivatives of non-kosher species are not kosher;2 this would include camel’s milk and ostrich eggs. Since a bee is a non-kosher insect, how can honey which comes from a bee be permissible to eat? Furthermore, if honey is kosher, are all products manufactured by the bee, e.g. royal jelly, beeswax, bee venom, and propolis (described below) also kosher?

When it’s Null and Void: Understanding Batel BShishim (One-Sixtieth)
Published Spring 2011
“She is too nervous to come to the phone,” said the woman, referring to the mother of the Bar Mitzvah boy, who had just prepared a huge pot of chicken soup for the upcoming seudas Shabbos. The woman then related the following story to me. The Bar Mitzvah boy, who was home from school on the Friday before the big Shabbos, had warmed up some pizza in the toaster oven on a piece of aluminum foil. After completing his lunch, he crushed the used foil into a ball and attempted to shoot it into the garbage can. The foil ball missed the trash and landed in the large pot of chicken soup, simmering on the stove in preparation for his seudas Bar Mitzvah! The woman on the phone got right to the point. “We discarded the foil. Does the soup need to be thrown out, and do we need […]

There was a time not long ago when kosher food was available only in major Jewish metropolitan areas. Finding kosher certified products on the road was a daunting task. “Kosher Tours” were limited to a few select areas. Today, the Star-K and other kosher symbols appear on thousands of food products. Kosher food is available from Fairbanks to Fiji, and from New Zealand to Norway. Kosher tours are now available to Alaska and Antarctica. With so many north and south destinations easily accessible to kosher consumers, the observant Jew now faces an array of fascinating questions. In parts of Alaska, and other locations north of the Arctic Circle, there are […]

She Sells Sea Shells: But Are They Kosher? The Kashrus Status of Glucosamine and Other Arthritis Remedies
Fall 2001
As the kosher consumer crosses Maryland’s spectacular Chesapeake Bay Bridge, it is hard to imagine that glucosamine, one of the most widely used arthritis remedies, is derived from the seafood shells found deep in the waters below. Sea shells are not the only surprising source of muscle and joint remedies. The levona (frankincense) used in the Beis Hamikdash, deer antlers, and an array of animals – including sharks and bees – also contain the raw materials of over-the-counter arthritis supplements.
STAR-K receives numerous inquiries regarding these products. This is no wonder, as over 40 million Americans suffer from some form of arthritis, and billions of dollars are spent each year on prescriptions and remedies. The following is an overview of how these products are manufactured and their kashrus status. Note: See disclaimer below.1
Glucosamine
The raw material for most glucosamine comes from crab, shrimp or lobster shells. Unlike oyster […]

The patient may be confused about whether a particular product is kosher. The following guide was prepared to help clarify the kashrus issues regarding these products.[1]
