Before hachshers were around Yidden would always purchased salmon fillets without Hechsher. You just need to see the skin has scales. There is no issue.

Steam
April 3, 2016 3:37 pm

I don’t understand this whole ‘Heter’ of steamed. If for example I have a pot of potatoes, and only half of the pot is under water, is the top half considered ‘steamed’ that can be eaten if a guy turned on the fire.

Even if you conclude that this example is different, cause they are touching, how about a convection oven, the fire is concealed and only ‘steam’ is baking the food, similar to the steam this person is talking about that ultimately there is a fire, only that the fire is in the room next-door.

This is OU’s opinion of on cereal.

Many Frum yiden and all Chasidishe Hashgoches don’t agree with this.

We should not accept a OU Mashgiach (that don’t stand for Pas Yisroel and Cholov Yisroel) as Lubavitch views.

what about tuna
April 3, 2016 2:21 pm

does tuna need to be bishul yisroel???

This person contradicts himself
April 3, 2016 2:09 pm

First he says that the Cheerios is not pas Akum cause it’s only thru steam. Then he says that hot steam is called backing….

LOL

The ou themselves claim that any fish can be colored: https://oukosher.org/blog/consumer-kosher/the-kashrus-of-skinless-salmon/

European living
April 3, 2016 1:28 pm

i live in an european country with no kosher fish stores…even if a not kosher fish touches your fish it does not make it treif. Being that the fish is cold..all you need to do is rinse it well when you come home. We choose our fish so we see that it has fins and scales and they fillet it for us.

as long as cold cereals have reliable hechsher, e.g. ou, c.o.r., alot of plain k on kellogs from u.s. [you have to find out] it is permissible to eat. no inyan of bishul yisroel since cereals are all basically toasted. toasted is not baked!
as long as raw salmon and canned salmon have some skin on, it’s also definitely o.k. to eat!
of course, if you want to be more machmir or the like ask your local orthodox rabbi!

Cheerios
April 3, 2016 11:10 am

Cheerios, as his said, is made as a dough, that was hot steamed and therefore became pas akum.

Based on the valid questions

In these comments can Rabbi N or R Wilhelm please answer and clarify for those of us who have concerns.
Many thanks

April 2, 2016 11:29 pm

With all due respect, Seemingly from shulchan aruch, as long as the jews rebaking the bread improves it, it seems that it should be 100% pas yisroel, and It doesnt seem that it should make any difference or not if you one time ate the par baked bread without re baking it, as long as at the end of the day the bread improves through the rebaking. (The rema is even lenient with bishul which is more stringent) Seemingly, seems a bit shver to say that tortillas which are 100% baked, all of a sudden become pas yisroel by heating… Read more »

Cut Salmon needs a hechsher
April 2, 2016 11:16 pm

Even though rabbi Nathenson maybe right that no non kosher fish can be colored to the color of salmon. Cut or filleted salmon need a Hechsher, unless you buy it from a manufacturer who processes large volumes of salmon.
The salmon in costco is not good without a Hechsher, since it gets trimmed in the deli section with knives and boards full of non kosher fish!
Please be aware!

I think everyone who wants to comment needs to stop acting as if they are a Posek. Now everyone is smarter than the OU? I was waiting for all these comments to see how ‘frum’ everyone is. Also, did anyone actually watch the video beofr commenting? Thank you Rabbi Nathanson, and keep informing us.

From another kashrus professional, Hatzlacha

Raw salmon dies not need a hrchsher
It is impossible to color is fish enough to change it from white to Pink
About the cleanliness of the knives in a major Supermarket they will never use the same knife from one type of fish to another and they will always watch it they can have major problems if they do not carefully clean a knife from one surface to another

Lox - bishul Yisroel
April 1, 2016 4:47 pm

Star K writes on their web site that Lox needs to be bishul Yisroel, because facility needs to be bishul Yisroel, same smoke ovens can be used for cold and hot smoke, so even if we say that Lox dont need to be bishul Yisroel, the oven it smokes in should have status of bishul Yisroel Oven siince it may be used sometimes for hot smoke

No one out there like Reuvan Nathanson!
April 1, 2016 4:46 pm

Rabbi Nathanson is the most educated, dedicated kashrut expert out there. He is Down to earths and practical. Never an alarmist or holds stringincies unnecessarily, while being strict and honest! He is always generous with his time to answer kashrut questions. A true cod did and credit to Lubavitch. (Not a relative!)

April 1, 2016 2:59 pm

Quite a # years ago,Yeshiva Oholei Torah once received a donation of $10,000. worth of Cheerios,R MIchoel Teitlebaum Obm. contacted Lubavitcher Rabbonim, & he ended up returning the whole shipment.

Change title
April 1, 2016 2:41 pm

You should write RAW salmon… Someone may misinterpret.

China colors its fish to look like salmon. I was told that unless it has a hechsher I can not buy it since it may not be kosher

if you see the skin
April 1, 2016 1:29 pm

if the skin is still on, I was told by tartikov hashgacha

salmon ques
April 1, 2016 1:09 pm

Doesn’t it matter what knife was used to clean the salmon and cut it. Maybe knife was used on non kosher fish before. So how can you buy salmon fillet without a hechsher?

Curious??
April 1, 2016 1:02 pm

Can one buy fresh salmon from let’s say Costco without a hechser?

o-u is maikil with fish
April 1, 2016 12:44 pm

the title is very misleading. just bec. they say i’s okay, doesn’t mean it’s okay for us. each person should consult his rov.

Salmon
April 1, 2016 11:52 am

So, just to clarify, one can buy frozen plain salmon filets without a heksher? ( The CRC says yes, Ive done it, but it feels funny)

April 1, 2016 11:43 am

Star-k holds that samon needs a hechsher or scales

Please answer
April 1, 2016 11:24 am

What’s if they add coloring to the salmon – are you allowed to buy without a hechsher?

Mashpia
April 1, 2016 10:36 am

Title is very misleading. According to most Poskim it does. Please revise.
