Not sure who told you "they were good to eat"....but
tried Capybara in Panama....prepared with LOTs of garlic, soaked in wine and peppered with spices and it still tasted of rat.
I'm truly an adventurous diner.......but I really couldn't finish my meal.
The only other thing that put me off over many years of travel and exotic foods, was the Sea Cucumber in China. Looked like a giant gray turd, and tasted like cardboard soaked in weak tea.
