Bacteria in the Cafeteria

Why is yogurt with live acidopilus and bifidus cultures kosher to eat if we are not allowed to eat bugs?

Dear David,

Good question. Now let me ask you one: Why are we allowed to breathe? Zillions of microorganisms are floating around in the air, and we swallow some with every breath.

The answer is: The Torah prohibits only bugs which can be seen by the naked eye. Organisms seen only with the aid of a microscope are kosher.

The logic is this: The Torah was given to human beings, not angels. Its laws are geared to normal human experience. Bugs we see in 'real life' are forbidden. 'Invisible' ones - which seem like they exist only in a laboratory - are not forbidden.

When improved microscopes brought improved awareness of microscopic organisms, some people suggested that perhaps we should filter our water to avoid consuming the organisms. A renowned rabbi responded: "If you give a nickel to charity while holding it under a magnifying glass, do you get credit as though you gave a dime?"

Speaking of germs: Three amoebae are sitting on a park bench. Suddenly, one of them jumps up and runs off.

"Hey! Where did Harry go?" one asks the other.

"Guess he had to split."

Are all men with the last name KAPLAN kohens?

Dear J. Kaplan:

Often, people named Kaplan are kohanim. This name is said to mean "Kohen Ploni" - "So-and-so the Kohen." Katz, another name common for kohanim, means "Kohen Tzedek" — "Righteous Kohen."

But having a name like Kaplan or Katz isn't proof of being a kohen. Two of my best friends are named Kaplan, and neither one is a kohen. In fact, I know someone named Cohen who is not a kohen!

A kohen is a male descendant of Aharon, Moses's brother. If you have a family tradition that you are a kohen, and that family members were called to the Torah as kohanim, then you need check no further.

If there is no family tradition, other evidence is required. For instance, an ancestor's gravestone inscription. Someone who can't determine his father's personal status is automatically considered a Yisrael.

Try looking up long-lost relatives, and ask them. If you are like many people, you may very well have relatives here in Israel, Russia or elsewhere whom you don't even know.
