Heavy metal contents in organic baby-food-carrots

High-quality requirements in a premium-quality supply chain are needed to ensure baby food quality standard in plant production by avoiding a too high uptake of lead, cadmium and mercury. Carrot (Daucus carota L.), onions (Allium cepa L.) and potatoes (Solanum tuberosum L.) were tested in this study. It is important to have very low-level thresholds of concentrations NDASH but at higher prices - to the food industry. A sampling of crops was done on the field, and results have been compared to concentrations in soil samples exactly from production (“from field to fork”). Occasionally, the thresholds of chain-internal baby-food standards were exceeded, which resulted in financial losses for the growers (but harvest still was suitable for marketing in organic chains). A strict resources canon left only soil-borne pollution due to some light heavy-metal freight of few harvests. All samples were suitable for an organic marketing and almost all for baby food. The different species (and cultivars of carrot) exhibited different levels of uptake. It is important to strictly hold soil pH and the correlating contents of clay and humus. Carrot cultivars from growing sites showed to have significantly different uptake of heavy metals. Suggestions are presented for soil management to reduce the risk of violating the rigorous standards for baby food produce.
