Over the past number of years, there has been much discussion regarding insect infestation and the procedures used to check fruits and vegetables. Many guides have been published, many lectures and demonstrations have been given, L’Hagdil Torah Ul’hadira. However, infestation can and does change over time,1 so it is worthwhile to step back from time to time and review the facts as well as the procedures used.

On Wednesday, September 7, at 8 p.m. EST, STAR-K made history by hosting the world’s first Eruv-inar. The inaugural long distance interactive presentation allowed participants from around the globe to experience a live workshop highlighting eruv shaylos through the use of pictures of eruvin. STAR-K’s Rabbinic Administrator, Rabbi Moshe Heinemann, shlit”a, has always been on the cutting edge of the juxtaposition of advanced technology and halacha; the Eruv-inar featured Rav Heinemann discussing hilchos eruv.

Torah-observant Jews know that turning on the hot water faucet during Shabbos causes cold water to be heated, which transgresses the melacha of Bishul, cooking. What many don’t know is that even turning on what you think is cold water can be a problem – if it’s a one-handled faucet.
Let’s first analyze why using hot water causes cold water to be heated. In a typical home setting, cold water arrives from the city supply under pressure. Turning on the hot water faucet allows this cold water into the hot water tank which, in turn, forces out the hot water already in the tank. Since the water in the tank is typically more than 120°F (the minimum temperature for bishul on Shabbos), the incoming cold water is immediately heated by the hot water that is already in the tank. 1

STAR-K has researched breakfast cereals for the past 30 years and has published Brachos lists and halachic guidelines for these products based on the psak of Rabbi Moshe Heinemann, shlita, STAR-K Rabbinic Administrator. It is with great pride that STAR-K has begun certification of the following three cereals distributed by Nestle in Israel: Cheerios, Fitness, and Crunch Cereals. The hashgacha is coordinated by our newly expanded Israel office. The products bear a STAR-K symbol and are pareve, bishul Yisroel, and yoshon. The brocha rishona on all three cereals is mezonos and the brocha achrona is al hamichya.

One of the trademarks of the Star-K is that it encourages its staff to respond to consumer kashrus inquiries. All too often, after eating a yummy treat, a consumer will notice a seemingly questionable item listed on the wrapper’s ingredient panel. They will then call the Star-K hotline in a frantic state because they fear they may have eaten something non-kosher, only to learn that they most likely mistook the ingredient for something else or that the ingredient has a kosher counterpart. The following is a list of commonly questioned ingredients that regularly appear on the labels of popular foods that we eat.

Since the Star-K often receives questions regarding the use of electric shavers, this article will address the halachic concerns of removing one’s facial hair. The Torah states “לא תקפו פאת ראשכם ולא תשחית את פאת זקנך” , Do not round the corners of one’s head, and do not destroy the corner of one’s beardויקרא י”ט כ) ). The Torah continues, “ופאת זקנם לא יגלחו” (ויקרא כ”א ה ) and the corner of one’s beard they shall not shave.

Q: I have a number of utensils which need kashering through hagalah (immersion in boiling water). Which materials may and may not be kashered?
A: A fleishig utensil which comes into contact with hot milchig food or a milchig utensil which comes into contact with hot fleishig food needs to be kashered before further use. There are a number of methods for kashering, dependent upon the manner of contact between the utensil and the food. Perhaps the most common form of kashering is hagalah, in which the utensil is immersed in boiling water.
Metal
The Torah tells us that a vessel may be kashered if it is made from one of six metals: gold, silver, copper, iron, tin or lead.1 There are other metals and alloys which were not in common use at the time of Matan […]

Not too long ago, prior to the flood of Jewish children recordings, my children listened to a popular recording of birthday party songs. One popular song that stands out in my memory is the song beginning with the following lyrics:
Everyone loves ice cream, yes indeed they do,
Everyone loves ice cream, I do – do you?
Search the whole world over travel near and far,
‘Cause everyone loves ice cream, no matter where they are.

The Community and Its Shechita
One of the most basic features of a functional Jewish community, no matter the size, has historically been the shochet. Rabbis are a necessity, but were not always available; access to kosher meat is indispensable. The original American Jewish community of twenty-three Dutch Jews from Brazil, who landed in New Amsterdam (later, New York) in 1654, was led by the celebrated Asser Levy, who was also the shochet. Well before the first ordained rabbi, Rabbi Abraham Rice, arrived in 1840, shochtim served the needs of American Jews.
In the more established kehilos of Europe, the shochet was also deemed critical. An intrepid shochet, who risked his life in the early 1930s to provide kosher meat to Jews in Soviet Russia, remarked during an interview:

Unquestionably, the latest operative terms in the burgeoning liquor industry are ‘transparency’ and ‘innovation’. Never before has there been more consumer enlightenment, courtesy of the information highway known as the Internet. Moreover, new venues have been introduced to tweak standard products or present new ones, so that distilleries can gain a greater share of the market. What previously was assumed to be a glatt kosher choice in the liquor cabinet has now become not so glatt.

Q: I am going to Israel and will be visiting the kosel (Western Wall). I know that it is customary to tear kriah upon seeing the kosel, but what exactly is the procedure?
A: The Shulchan Aruch paskens that when a person sees the cities of Judea he should say,
ערי קדשך היו מדבר and tear kriah.1 However, it is not customary to do so, possibly because we do not know exactly where the ancient cities of Judea are located.2 The Shulchan Aruch continues that when a person sees the Old City of Yerushalayim he should say, ציון היתה מדבר שממה , and then tear kriah again.3 Rav Shlomo Zalman Auerbach zt”l writes that even nowadays, one should tear kriah upon seeing the Old City.4 However, Rav Moshe Feinstein […]

The eighteen mashgichos who attended STAR-K’s Mashgicha Enrichment Program, November 2-3 in Baltimore, Maryland, had only one complaint: it wasn’t long enough. Although it lacked nothing in the way of organization or detailing of comprehensible and practical information, the women would have appreciated even more face time with the STAR-K experts. The experience of meeting fellow mashgichos from so many communities, being able to ask questions throughout the presentations, and the camaraderie felt by the program’s end, made it worth the trip!

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 […]

Summertime is a season synonymous with travel, vacation, and experiencing the great outdoors. For many, the great excursion meant traveling to Bubbi’s bungalow colony in the country. Today, we vacation the length and breadth of America. As we venture further and further away from the Catskill corridor, and experience the heartbeat of America, a universal question crosses the mind of every frum vacationer: “Is there anything Kosher to eat out there?” The answer is yes, more than you think; but it is still wise to plan before your journey.

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:

Cookin’ just ain’t what it used to be. Technological advances have taken the old stovetop and oven and upgraded them to be safer, more efficient, and smart for today’s lifestyle. They are also far more complicated. With these transformations, the observant Jew is faced with challenges that did not confront him in the past.
To understand how these changes affect the halachic use of the stovetop on Shabbos and Yom Tov, it is worthwhile to review some laws and concepts as they relate to cooking on Shabbos and Yom Tov.
DEFINITION OF MELACHA
Cooking on Shabbos is a Torah prohibition derived from the constructive acts performed in erecting the mishkan. This forbidden act is known as a melacha. There are 39 categories of prohibited acts.

Hashem, in His eminent act of chesed, created a world with abundant gifts expressly designed for the enjoyment of man.

Few of us can remember life in the kitchen without the help of a refrigerator. Probably the most used appliance in the home, the electric refrigerator was mass produced as a home appliance in the early 1920’s. Although many improvements and modifications have taken place over the years, the basic principles employed in the home refrigerator remain the same.
How Refrigeration Works
The natural laws of physics dictate that as a liquid evaporates into a gas, it absorbs heat from the surrounding areas. In turn, these surrounding areas become cold. (If you touch the cylinder supplying gas to a barbecue grill, you will notice the cylinder getting cold and icy because the liquid in the cylinder is rapidly changing to a gas as it leaves the cylinder to provide fuel for the flame.) Although we may view our refrigerator as […]

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

When visiting an obstetrician/gynecologist, a patient may be given prescriptions or recommendations for an array of products by her physician. 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]
Ideally, one should purchase medicinal products and vitamins with a reliable kosher certification. Unfortunately, this is not always possible. In the event a product is not kosher approved, one should consult her rav, as one does with any halachic question.
The following guidelines in this regard are the halachic ruling of Rav Moshe Heinemann shlit”a, STAR-K Rabbinic Administrator.
NOTE: The following are general halachic guidelines and cannot possibly cover all scenarios. Under no circumstances should an individual forgo taking a prescribed medication without first consulting her physician and rav.
