Chometz Sheavar Alav HaPesach

By Rabbi Dovid Bistricer Pesach is a period full of kashrus related halachos. During this unique time we observe various dietary restrictions, which are part of the holiday’s special “halachic diet”. However, kashrus issues associated with Pesach do not end with havdalah after the last day of yom tov. Chometz sheavar alav hapesach, a term that describes chometz that was possessed or controlled by a Jew during Pesach, is strictly forbidden after yom tov is over. This issue is unfortunately quite relevant, since many food manufacturers, distributors, and retail stores may have either full or partial Jewish ownership. In each of these sectors, unless the party or parties involved are shomrei Torah u’mitzvos, any chometz in their possession may very well be forbidden after Pesach.

Microscope

By Rabbi Dovid Bistricer We live in a world of technological advancements. How we approach new inventions, medical procedures etc., and their impact on halacha can be highly complicated and very confusing. We have therefore been blessed from one generation to the next with Gedolei Yisroel whose broad shoulders have borne the responsibility to address these types of issues. This article will focus on a not-so-recent technological advancement, but one that nevertheless has been discussed quite extensively by poskim, the microscope.

Succos

By Rabbi Dovid Bisticer The connection between kashrus and Yom Tov is fairly apparent during Pesach. During this special holiday, chometz is strictly prohibited and we fulfill a very unique mitzvah of eating matzah. There are many intricate halachos associated with baking matzah, which if not performed properly, render one’s matzos to become chometz. There are also many halachos associated with the kashrus of wine used for daled kosos, the maror that we eat at the seder, and the list goes on. However, Pesach is not a holiday that has a monopoly on kashrus concepts. Areas of kashrus are also touched upon during other times of the year, even though sometimes the connection may seem hidden. Succos is no exception, as there are topics dealing with kashrus and eating, which are associated with this special time.

Eggs and Blood Spots

By Rabbi Brun-Kestler In the past, most eggs came from fertile hens, whose increased hormone levels stimulated more egg production. Of course, fertilized eggs will also, in the right conditions, grow into chickens. In modern commercial egg operations, this hormone enhancement is achieved (and controlled), by artificial means through the feed and the eggs themselves are not fertile; they will never develop into chickens. While in the past, every bloodspot might have signified the beginning of a new embryo (safek sheretz ha’of), today’s commercial methods virtually insure that this is not the case.

Gluten Intolerance, Celiac, Allergies And Pesach

By Rabbi Avraham Juravel Pesach Kashrus professionals are familiar with the intricacies of ingredients and food production. Often, consumers who have health concerns contact kashrus agencies in order to obtain information about foods and ingredients. This is especially true when it comes to Pesach. Before Pesach, the consumer information lines at the major Kashrus agencies are constantly ringing. Many of these consumers ask question about Pesach and their health needs. This article will discuss some of the ways in which Pesach certified foods may impact on health issues. However, it is important to note that kashrus agencies and Rabbonim are not health specialists. Persons who need guidance with respect to health matters should obtain advice from qualified health specialists, not from kashrus agencies.

Tevilas Keilim

By Rabbi Nachum Katz The Mitzvah of tevilas keilim is alluded to in Bamidbar 31:23 where Elazar HaKohen instructs the army returning from war with Midyan regarding the booty they have captured “Kol davar asher yavoh ba’aish ta’averu ba’aish v’taher”—All utensils that have been used to cook ma’achalos assuros must be purged of the flavor they have absorbed in the manner that they were used. V’taher—they are then made tahor through an added step of purification.
