Abstract

Polybrominated diphenyl ethers (PBDEs) as flame-retardant additives have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles. They are structurally similar to PCBs and other polyhalogenated compounds. PBDEs are found in a variety of foods, and 95% of all human exposure to POPs comes from food. The major food sources are fish/seafood and dairy products. A number of studies have reported high levels of PBDEs in animals, increasing the public's concern over PBDE levels in animals. This study evaluates the relationship between the level of PBDEs according to piglet diseases. Salmonella spp. and Streptococcus are bacterial diseases. Porcine respiratory reproductive syndrome (PRRS) is a viral disease. The concentration of PBDEs in the piglet liver from viral diseases was higher than that from bacterial diseases. BDE-47 and BDE-99 were detected in most samples. More PBDEs were detected in the piglet liver from PRRS of North American type than from that of European type.
