Dioxins in food: a modern agricultural perspective.

This review attempts to cover and summarize the literature available on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in the environment with regard to problems of interest to agriculture. The coverage of the literature is extensive (120 references) but, by all means, not complete. Issues that are addressed in this review include a background summary of dioxins in the environment and their potential human health risks; current knowledge on the levels of dioxins in the U.S. food supply and comparisons to European data; descriptions of recent food contamination episodes; an evaluation of methods that may reduce incurred levels of dioxins in livestock and meats; and the status and limitations of dioxin analysis and rapid screening methods with regard to widespread monitoring programs. Research areas in agriculture where data and experimental results are scarce or nonexistent are also pointed out.
