The toxicological analysis of lead and cadmium in prescription food for special medical purposes and modified milk products for newborns and infants available in Polish pharmacies.

There is currently a lack of risk assessments around Pb and Cd in prescription food for special medical purposes (FSMPs) and modified milk products available in from pharmacies in Poland. This article describes and evaluates a toxicological analysis of lead and cadmium in prescription FSMPs (n = 6) and modified milk products (n = 6) available in Polish pharmacies. The metals were determined using electrothermal atomisation atomic absorption spectrometry. To make the appropriate risk assessment, we considered (1) the levels of lead and cadmium in a powdered product, (2) the amount of the metals consumed in one portion (single exposure), (3) the daily dose depending on age (months) and body weight and (4) the weekly intake of Pb and Cd in samples in comparison to provisional tolerable weekly intake (PTWI). The results demonstrated that the samples analysed do not represent a health hazard to newborns and infants. This study is important because of the concerns around the complex risk assessment of prescription FSMP's and modified milk products available in Polish pharmacies related to lead and cadmium.
