Food toxicology--from forensic to policy tool: an evolution from reactive to proactive action.

Since the nineteenth century, food toxicology has evolved in several ways. The analytical power of the food toxicologist has been increased. The concept of adulterated food was modified significantly. Most commodities are now processed and addition of numerous non-nutrient additives is legalised. Other "alien" compounds get introduced in the food chain from background contamination or during processing and distribution. This makes the task of the food toxicologist more complex. From forensic science food toxicology developed to a policy aid.
