Screening for toxicity[edit | edit source]
- Chemical hazards data - OpenFoodTox -- When evaluating the safety of chemicals, scientists determine if and how they may be hazardous for humans, animals and/or the environment. They seek to identify critical health effects for these populations, the amount of the substance likely to trigger the effects, and then where possible establish a safe level. 
- Compendium of Botanicals- EFSA’s Compendium of Botanicals is a database of botanicals that are reported to contain naturally occurring substances of possible concern for human health when present in food.
