Abstract
Intake of home-produced foods may be a concern in areas where chemical contamination exists. Estimating exposure to contaminants in home-produced foods requires knowledge of the amount of these foods consumed. The US Environmental Protection Agency's (US EPA's) Exposure Factors Handbook provides data on consumption of home-produced foods based on the US Department of Agriculture's (USDA's) 1987-1988 Nationwide Food Consumption Survey (NFCS), the most recent national food survey that contains the information necessary to estimate home-produced consumption. These data represent "consumer-only" intake rate distributions for various age and demographic categories. "Consumers-only" information is also provided for households who garden, farm, and raise animals for all age groups combined. However, these "consumer-only" values may not always be appropriate when assessing chronic exposures. Furthermore, data for all ages combined may not be useful for estimating exposure among age groups that may be of particular concern. This paper provides age-specific "per capita" intake rate distributions of home-produced foods specifically for the populations that garden, farm, and raise animals, using data from EPA's Exposure Factors Handbook.
