Bitul

A summary of the OU’s position about using bitul in Kosher food productions.

Mailbox י”ז תמוז אשר במהרה יתהפך לנו ליום שמחה כבוד הרבנים החשובים שליט”א תמוה לי קצת הנושא אודות חשש בישול גוים – כי ראיתי הרב בעלסקי שליט”א כותב שכל מתחלה נעשה הבישול רק כדי לעשות ממנו דבר שאינו עולה על שלחן מלכים אז אין כאן חשש בישול עכו”ם [וזה ההיתר שנוקטים האו יו ברייז קריספיס, […]

Constant Review Is Required: An Inspection Report

When this plant was first set up as a kosher facility, it was known that they had a non-kosher plant that produces assorted products on the same campus. Of course, the issue of steam return condensate was brought up. It turned out that condensation from the non-kosher factory was not being returned to the boiler so there was no problem to certify the kosher division.

Recycled Ingredients

A basic phenomenon in chemistry plays a crucial role in industrial kashrus. When two chemicals react with one another, one will be used up before the other. The chemical used up first is called a “limiting reactant” and the chemical which is not used up is an “excess reactant”. Often the excess reactant is recovered, purified, and used again in another production.

Fish and Meat

The Gemara Pesachim (76b) teaches that one may not cook fish and meat together since this combination is considered a sakana. Shulchan Aruch (Y.D. 116:2-3) adds that one may not even eat meat after fish or fish after meat unless one eats and drinks in between1. Rama adds that one should not cook open meat and fish in the same oven because of raicha (aroma), though bidieved we say that raicha lav milsa. Magen Avrohom (O.C. 173:1) questions whether this sakana still exists today, however the minhag is still to be machmir.

How Pas Yisroel is Created

The Mishna in Avoda Zara (35b) tells us that Chazal forbade pas akum. The Gemara (36b) explains that this was done as a geder to avoid intermarriage. However Tosfos1 bring a Yerushalmi that says that a later Bes Din removed this issur. The exact extent of this retraction is a disagreement between the Mechaber and the Rama. While all agree that bread baked by an akum for personal use is still forbidden, there are differing opinions as to how careful one must be to avoid eating pas palter, bread baked by an akum for the purpose of selling.

Drinking Coffee on the Road

Considering the long days that Mashgichim put in and the hundreds of miles that they drive daily, it is no surprise to hear that most mashgichim rely on coffee to keep them going. While caffeine is a plus for those who work in an office, for those out on the roads those 10 minute coffee stops are quite literally life savers. Let us take a moment to understand if there are any kashrus concerns with picking up a coffee while traveling on the road. This question was presented to the OU poskim Rav Schachter and Rav Belsky.

Initial Release Of OU KOSHER’s “How To” Audio/Video Series Generates Much Excitement Worldwide

Requests have been coming in to Orthodox Union from Israel, Mexico, Australia and around the globe for OU Kosher’s new “HOW TO” audio/video series. Based on the OU’s highly acclaimed ASK OU and ASK OUTREACH programs, the series have gone into wide distribution, with a sixth being added to the first five that were recorded. The series consist of numerous Kashrut Seminars that took place in Lakewood, NJ and OU headquarters and offer a step-by-step explanation of various topics that reflect the intricacies of the laws of kashrut. Both the seminars and audio/video series are sponsored by the Harry H. Beren Foundation of Lakewood.

Mechiras Chametz

Mechiras chametz accomplishes two functions. It prevents the owners of the chametz from violating the issurim d’oraisah of ba’al yiraeh uba’al yimatzey and it saves the chametz from becoming chametz she’avar alav hapesach (mid’rabanan). Ideally we try to arrange all sales in the most lichatchila manner so as not only to protect the kashrus of the products but also to prevent the owners from violating issurim.

Mechiras Chametz today is typically arranged by authorizing a Rabbi to act as the legal agent on behalf of the one selling the chametz. This same procedure is utilized in regards to mechiras chametz for companies. However the question arises, who may authorize the sale of chametz on behalf of a Jewish owned company?
