Exposure to PBDEs associated with farm animal meat consumption

One of the ways to reduce the number of fires and the amount of damage caused by them is to use flame retardants (FRs). Polybrominated diphenyl ethers (PBDEs), like other FRs, have been used in a wide array of easily flammable products. As they are not chemically bonded with materials, PBDEs can be released from polymers into the environment. PBDEs can act as endocrine disruptors and affect neurological and thyroid activity. Although human intake of PBDEs is mainly through food, data about meat as a PBDE source and human exposure through diet are limited. The objective of the present study was to develop a comprehensive database of congener-specific PBDE concentrations in farm animal muscle and to characterize potential consumer exposure. For exposure assessment, two consumption scenarios were used for adults and children. The dietary exposure to PBDE congeners is based on the assumed portion size of 100 g of different meat species. Calculations for the participants were performed using food consumption data of the Statistical Yearbook (2015/2016). The intake of PBDEs was estimated as the median (P50) and the average for all kinds of tested meat. For health risk assessment, the margin of exposure (MOE) approach was used. MOE values were in range from 5 to 149 352 132. The obtained results indicate that concentrations of ten tested congeners (BDE-28,47,49,99,100,138,153,154,183,209) in different kinds of farm animal meat (cow, chicken, farm deer, horse, ostrich, pig, rabbit, sheep, turkey) are low and meat consumption does not pose a risk for human health.
