Been following this one with interest.........
And after thinking about it a while I'll admit that while I agree that it was probably "safe" once cooked, and may have even tasted good, I'd of not eaten it.
And I say this being someone who cleans fish for a living, have for 35 years, so I'm not what you'd characterize as squeamish.......but there are lines.
Worth knowing too that if something like that was found in one of the big tunas or swords, or maybe in a fat gator, I'd not feel safe in selling the meat.
Having said that I have to admit that I can give you no logical reason for taking that position.........squeamish I guess......
