Cadmium Maximum Levels and Residue Situation in the German Wheat and Rye Harvest from 1975 to 2021

For a better understanding of cadmium (Cd) accumulation over long time periods in cereals, Cd levels of the German wheat and rye harvest from 1975 to 2021 were analyzed. Overall, wheat had higher grain Cd concentrations than rye. Comparing mean values from different time periods showed that Cd level...

Zusammenfassung:For a better understanding of cadmium (Cd) accumulation over long time periods in cereals, Cd levels of the German wheat and rye harvest from 1975 to 2021 were analyzed. Overall, wheat had higher grain Cd concentrations than rye. Comparing mean values from different time periods showed that Cd levels in winter rye have stabilized, while Cd concentrations in winter wheat have decreased. Furthermore, Cd concentrations in almost all samples were below the newly introduced European Commission limits specifying the maximum permissible contaminant levels in foodstuffs (Cd in grains: rye 50 μg/kg FW; wheat 100 μg/kg FW). However, it is important to note that Cd is still ubiquitous in the German wheat and rye harvest. Although there has been a significant reduction in emissions and imissions for around 30 years, the extraordinarily long biological half-life and carcinogenicity of Cd still make it a relevant substance to food safety and human health.
