I do not believe that this is correct. If a "kosher" aid echad (legally
acceptable witness) sfaradi (from [Spanish or] middle eastern descent)
informs me that he or she knows that this locust or grasshopper is kosher I
have every right to accept that testimony according to Jewish law. Once I
am taught to discern the kosher species I, now, have every right to go and
teach it to others. I do not believe that there is any disagreement on this
fact.
This is very different from the turkey which everyone agrees is indigenous
to the Americas.
