Fish and shellfish are excellent sources of nutrients, but exposure to environmental contaminants can also occur from fish consumption. Estimates of usual fish and shellfish intake are needed to assess chronic exposure to environmental contaminants. While consumption rates based on short testing periods provide useful information on consumption over short periods, the intra‐individual variation of consumption from day to day presents unreliable information on chronic exposure. Using a probabilistic approach, data from the National Health and Nutrition Examination Survey (NHANES) 1999‐2000, 2001‐2002, 2003‐2004, and 2005‐2006, conducted by the Center for Disease Control (CDC) National Center for Health Statistics (NCHS), on the frequency of intake of fish and shellfish over a 30‐day period were combined with the dietary recall (24 hr) of fish and shellfish data from NHANES 2003‐2004 to provide estimates of chronic average daily intake of fish and shellfish. Over 300 NHANES food codes were mapped to 31 fish and shellfish categories; for each category, a weighted distribution of amounts consumed per eating occasion was generated from NHANES 2003‐2004 intake records. Long‐term (30‐day average) daily fish/shellfish intake rates were derived by combining randomly sampled NHANES individual records of 30‐day fish/shellfish frequency of consumption with amounts consumed per eating occasion randomly sampled from the intake distribution. The usual intake rates for all fish, all shellfish, and all fish and shellfish combined, as well as for individual fish/shellfish species for both children (1 to <2 years, 2 to <3 years, 3 to <6 years, and 6 to <11 years) and adolescent women (11 to <16 years, 16 to <18 years, and 18 to <21 years), as practicable (i.e., depending on sample sizes) are presented in this study.
