Bishul Akum at an Israeli Hotel

I was recently at a hotel in Israel. I saw an Arab employee who was making pancakes on the griddle. When I asked him who turned the griddle on, he replied that he had.

Waiting Between Eating Milk and Meat- Halacha and Minhag

I am very confused about a certain attitude among Orthodox people. Many people place a lot of importance on how long you wait between eating milk and meat. However, let us look at the source of waiting between milk and meat. It is just a rabbinic geder (fence) not to eat them together (when cooked separately) and a further geder not to eat them in the same meal. As a result, people in different cultures who had a meat meal would end up waiting the amount of time until the next meal to eat milk. The whole six hour/three hour thing doesnt seem to be so important, yet people make you feel so guilty if you take on a more lenient custom.

Non-kosher Ingredients in a Kosher Product

I am pretty sure that while I was doing some research on Kashrut some time ago I came across something called the rule of 100 or it could have been 1000. It basically stated that with most packaged food being made in large processing plants there is no way to say, unfortunately, that an insect could not have fallen into a mixer or what not. So the rule laid down a percentage, something like if there is a non-kosher ingredient in your food that you are unaware of and the ingredient makes up 1/100th or 1/1000 of the total ingredients by weight the product would still be considered kosher. Is this true or did I read some misinformation?

Does Liquid Calf Rennet need a hechsher?

I want to make my own cheese. Because I am making the cheese, there is obviously no issue of gevinat yisrael. But does the rennet need certification? Some reasons it should not are: the calf stomach's are dried and made like an etz bealmah or because the extraction of the enzymes is a davar chadash; there may be other reasons as well.

Toveling utensils before use when it has been obtained from a non-Jew.

I believe that it is a psik reishei (an unintentional but certain result) that a can opener will touch the food while opening the can. Therefore, it would seem to be required to tovel (immerse) the opener before use when it has been obtained from a non-Jew. Yet, I have not heard of people doing this. What is the correct practice?

Kashrut of an Animal Fed Meat and Milk

I have heard that veal comes from calves that are fed a mixture of milk and meat. Shouldnt that make it forbidden, as an animal whose sustenance comes from non-kosher food (see Rama, Yoreh Deah 60:1)? This case is particularly severe, because the feed is assur bhanaah (forbidden in benefit)!

Rinsing After Eating Pareve Food Cooked in Fleishig Pot

Is that right or does she have to take more precautions to make sure it stays kosher?

How to deal with kosher food in a non-kosher kitchen

A party is being planned in someone's house. Most of the participants don't keep kosher and some do. The food itself is kosher - it will come from a caterer - double wrapped (like in an airplane) with a good hashgaha. The problem is that the owner of the house is not observant so the kitchen in the house where the party is held isn't a kosher kitchen. They owner of the house promises to "self clean" their oven before the party, and then heat up the food in the oven while the food is still wrapped in the original wrapping. Is this food kosher? Can you tell me what the problems are and if there's anything I can do to make the situation better (the party is on a motzai shabbat?)

Selling vitamins, without a hashgacha, online

I have a business selling vitamins and supplements online. We sell to a nationwide audience that aren't necessarily looking for kosher vitamins, and a large portion of the brands that we carry don't have any kosher certification. It was brought to my attention that there might be a halachic problem with selling non-kosher products even when it's sold to a non-jewish consumer. I would like to get in touch with a rabbi who can give me general guidance on this issue, and if needed, to provide personalized guidance by looking at the individual items that we carry to determine if any of them have "trief" ingredients and if those items need to be excluded from our inventory.
