Assessment of the levels of lead, cadmium and mercury in livers and kidneys of two-year old from slaughter pigs and cattle in Germany

Description
Summary:In Germany so far there was only limited data on heavy metal pollution of livers and kidneys of two-year old or older slaughter cattle and pigs. With a pilot study should therefore be checked, what are the current contents of the three heavy metals lead, cadmium and mercury in livers and kidneys of older animals for slaughter, and determine whether differences between the three evaluated countries. Since the heavy metal enrichment increases in livers and kidneys, and the age of the animals, livers and kidneys were sampled from two years old or older cattle and pigs of lead, cadmium and mercury targeted. While hardly occurred for lead exceeded the maximum level, this occurred in cadmium and mercury. Regional differences occurred in mean comparisons of heavy metal contents in different countries in many animal organ-heavy metal combinations. It is shown how high the exposure for the population at the maximum measured concentrations of heavy metals in organs of cattle and pigs at an average consumption of livers and kidneys. Higher contaminated kidneys and livers contribute to part only in small part to consumer exposure to mercury and lead. The consumption of organs with higher cadmium levels may lead to an exhaustion of tolerable weekly intakes. From the perspective of consumer health protection, therefore, the contents of heavy metals especially in older animals should continue to be monitored.Original Abstract: In Deutschland lagen bisher nur wenige Daten zur Schwermetallbelastung von Lebern und Nieren von zwei Jahre alten oder aelteren Schlachtrindern und -schweinen vor. Mit einer Pilotstudie sollte daher ueberprueft werden, wie hoch die aktuellen Gehalte der drei Schwermetalle Blei, Cadmium und Quecksilber in Lebern und Nieren aelterer Schlachttiere sind, und ob Unterschiede zwischen den drei auszuwertenden Laendern festzustellen sind. Da die Schwermetallanreicherung in Lebern und Nieren mit dem Alter der Tiere ansteigt, wurden gezielt Lebern und Nieren von zwei Jahre alten oder aelteren Rindern und Schweinen auf Blei, Cadmium und Quecksilber beprobt. Waehrend fuer Blei kaum Hochstgehaltsueberschreitungen vorkamen, traten diese bei Cadmium und Quecksilber auf. Regionale Unterschiede traten bei Mittelwertsvergleichen der Schwermetallgehalte aus unterschiedlichen Laendern in vielen Tier-Organ-Schwermetallkombinationen auf. Es wird gezeigt, wie hoch die Exposition fuer die Bevolkerung bei den maximal gemessenen Schwermetallgehalten in Organen von Rindern u
