Axolotls are not poisonous in the way that many people think of venomous animals like snakes or certain fish. They do not possess venom glands or produce venom to harm predators or prey. However, like any animal, they carry bacteria and other microorganisms on their skin and in their environment.
It's important to note that handling axolotls, especially if you have open wounds or compromised immune systems, should be done carefully, as with any pet. The water in which axolotls live should also be treated to ensure it is safe and clean to prevent the spread of infections.
In the context of food safety, axolotls are consumed in certain regions of Mexico, and while they are not poisonous, they may carry parasites or bacteria that could be harmful if not properly prepared. Therefore, if eating axolotls, it's crucial to ensure they are sourced from reputable vendors and prepared in a way that kills any potential pathogens.
In summary, axolotls are not inherently poisonous, but as with any animal, appropriate care and preparation are necessary when handling or consuming them.
