There seems to be a lot of kashrut organizations that deal with their respective hashgachas. But rarely do they advise about other organizations or products that arent certified. Are there any websites or organizations that would answer questions about items that arent certified or dont need to be certified. Sort of like a neutral kashrut authority. Does such a thing exist?
Kashrut.org styles itself as such an organization. Note, however (as it posts on its home page) it has a decidedly anti-Kashrus Agency/establishment agenda.
In addition, on several European countries (England, France and the Netherlands I am familiar with personally, others probably as well) have the local Beis Din basically performing that function by issuing lists of acceptable products that are not actually certified.
The CRC (which is "Kashrus Agency establishment") also maintains several lists aimed at identifying products which can be used without formal certification. In addition, I know they take questions, although they aren't as public about it as Kashrut.org.
According to some people at the star k (for example) organizations are careful not to say something specific about other organizations or things that are not under their hashgacha for a number of reasons.
- If they do not certify something, they have often not been able to investigate it
- They cannot say that something is "not kosher" because that would be like libeling the people who do claim it is kosher
- They will at most say that something is "not recommended" unless there is something so obvious that anyone can see it
- There are so many products and certifying agencies that it is impossible to know about every single one.
