Global Environment Monitoring System - Food Contamination Monitoring and Assessment Programme (GEMS/Food)
GEMS/Food Short-Term Diets
New Call for Data
In recognizing that foodborne hazards can pose health risks after only a short period of exposure, GEMS/Food has assembled databases to allow for the estimation of one-day exposures to acutely toxic chemicals in food. For a pesticide residue with established an Acute Reference Dose (acute RfD), the International Estimated Short-term Intake (IESTI) may be used to estimate exposure based on the highest reported 97.5th percentile intake during a single day by consumers only that are reported by countries having such individual consumption data.
This exposure assessment methodology was developed by a series of FAO/WHO meetings and continues to undergo refinement by the Joint FAO/WHO Meetings on Pesticide Residues (JMPR). The methodology is based on GEMS/Food database for large portion consumption as well as on databases for typical unit weights and average body weights of children age 5 and under and the general population in the reporting countries.
The methodology and databases are available at: http://www.who.int/foodsafety/chem/acute_data/en/
