In Japan the consumption of the delicacy Fugu, or puffer fish, leads to 30-50 intoxications of humans per year, resulting in severe illness and sometimes death. The cause for this is tetrodotoxin (TTX), one of the most powerful neurotoxins known, many times more toxic than cyanide.

The antibiotic Florfenicol is brought on the market under various brand names and is used to control infections in cattle, pigs, poultry, and aquaculture. The compound is an effective broad-spectrum antibiotic and is considered as a less toxic alternative for chloramphenicol, which is banned world-wide because of its toxic effects.
