No, the excreta of lizards is not toxic and cannot cause death in a person. Lizard droppings, also known as lizard feces, primarily consist of undigested food particles and waste products. While they may carry certain bacteria or parasites that can be harmful if ingested, the risk of serious illness or death from direct contact with lizard excreta is extremely low.
It is important to maintain good hygiene practices to prevent the spread of any potential diseases or infections, including washing hands after handling any animals or their waste products. However, the idea that lizard excreta is inherently toxic and can cause death is inaccurate.
