“…Several experimental cattle feeding studies (Platonow et al, 1971; Saschenbrecker et al, 1972;Fries et al, 1973) have been conducted with the related polychlorinated biphenyl isomeric mixture (PCB) illustrating their persistent secretion in milk and tissue storage. The only published work involving PBB in cattle is that of Jackson and Halbert (1974) on the toxic syndrome which resulted when the feed, first suspected of contamination in Michigan, was fed to cattle.…”

“…Differential metabolism (Grant et al, 1971) and storage (Curley et al, 1971) of PCBs in rats has also been indicated. The excretion and persistence of PCBs in cows milk, its storage in tissues (Fries et al, 1972Platonow et al, 1971; Saschenbrecker et al, 1972) and its transplacental transfer in the bovine (Platonow and Chen, 1973) have been studied. Excretion of PCBs in the urine and feces was minor or undectable (Table IV) but some elimination of PCBs was observed in the urine and feces of preadolescent girls (Price et al, 1972).…”

Transfer of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) from oral exposure into cow’s milk – Part I: state of knowledge and uncertainties

Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) (collectively and colloquially referred to as “dioxins”) as well as polychlorinated biphenyls (PCBs) are persistent and ubiquitous environmental contaminants that may unintentionally enter and accumulate along the food chain. Due to their chronic toxic effects in humans and bioaccumulative properties, their presence in feed and food requires particular attention. One important exposure pathway for consumers is consumption of milk and dairy products. Their transfer from feed to milk has been studied for the last 50 years to quantify the uptake and elimination kinetics. We extracted transfer parameters (transfer rate, transfer factor, biotransfer factor and elimination half-lives) in a machine-readable format from 76 primary and 29 secondary literature items. Kinetic data for some toxicologically relevant dioxin congeners and the elimination half-lives of dioxin-like PCBs are still not available. A well-defined selection of transfer parameters from literature was statistically analysed and shown to display high variability. To understand this variability, we discuss the data with an emphasis on influencing factors, such as experimental conditions, cow performance parameters and metabolic state. While no universal interpretation could be derived, a tendency for increased transfer into milk is apparently connected to an increase in milk yield and milk fat yield as well as during times of body fat mobilization, e.g. during the negative energy balance after calving. Over the last decades, milk yield has increased to over 40 kg/d during high lactation, so more research is needed on how this impacts feed to food transfer for PCDD/Fs and PCBs.
