Famous Ioannides and Lewis Parke Quote
... numerous chemicals have been found to have potential toxicity/carcinogenicity in rat or mouse, which, we are reasonably certain, have little or no potential hazard in man. The reason for this is again species differences, for the biological defence mechanism which protects against toxic chemicals is most highly evolved in man, who therefore generally has a higher resistance to chemical toxicity and carcinogenicity than have rodents and other species.
