2.3. Dietary chlordecone intake assessment
Data about chlordecone levels in food come from a survey conducted in Guadeloupe from July 2006 to July 2007 (AFSSA, 2007). This survey was designed to assess the dietary intake of chlordecone in the general population older than 3 years, according to the WHO guidelines (FAO/WHO, 1997 and FAO/WHO, 2000). Factors considered in planning the types and numbers of samples to collect included the known contribution of foods to dietary chlordecone intake and the importance in the Caribbean diet of food items for which chlordecone contamination is not known. Local retailers and markets were divided into two strata based on their location in a polluted or an unpolluted area. The sampling places were drawn according to the food supply habits of the population, as described in the food consumption survey, with the same rate for each stratum (AFSSA, 2007). Self-production was also taken into account. European Union (directive 2002/63/EC) guidelines establishing community methods of sampling for the official control of pesticide residues in and on products of plant and animal origin were applied to collect the 744 food samples. Analytical methods and quality control have been described elsewhere (Bordet et al., 2007). Data were expressed as mean concentrations (μg/kg of fresh product) stratified according to the area where they were sampled (polluted or unpolluted areas of the island). The relations between the 59 items for which contamination data were available and items in the SQFFQ were determined to help attribute chlordecone values to the latter. When no information was available, assumptions were based on the same principles as those defined in previous dietary intake assessment studies (AFSSA, 2007).
Daily dietary intake of chlordecone was assessed for each subject according to a previously described procedure (AFSSA, 2007). The quantity of each food (or beverage) item eaten daily was multiplied by its mean estimated chlordecone level. Estimated quantities of chlordecone intake from all 214 items were then summed to obtain a total daily intake (μg/day). We designate this as the food consumption–food contamination approach (FCFC).
