Hi
I fell like you. I cannot find any publication elsewhere to support this, and therefor I asked here, if anyone knew anything about it.
As I said the story comes from "Field Guide to North American Reptiles and Amphibians " National Audebon Society.1979 ISBN 0-394-50824-6. Authers John L. Behler, Curator of Herpetology at the wildlife Conservation Society, and F. Wayne King, Curator of Herpetology at the Florida State Museum of Natural History.
I cannot believe that it is Salmonella. I newer heard that it causes paralyses. To me it sounds like a reaction to a pioson like botulism; poisoning caused by infection with bacillus botulinus.
Maybe anyone knows one of the authers?
Best wishes
