Targeted farm controls and smart processing minimize Cd/Pb in carrots while ICP-MS verification prevents exceedances. An integrated, multi-barrier approach reduces recalls, protects infant foods, and aligns with EU/FDA expectations for retailer-ready compliance.

This study evaluated heavy metal concentrations and health risks from vegetable consumption in polluted Romanian soils, finding that although soils are contaminated, the health risks from eating local carrots, onions, tomatoes, and peppers remain below critical levels, especially when monitoring and moderate consumption are maintained.

This study reviews a collaborative workshop on cadmium in Arizona and California-grown spinach and carrots, revealing key findings on sources, risks, mitigation, and the importance of multi-stakeholder engagement for heavy metal certification efforts.

This study quantified the bioavailability and speciation of arsenic in carrots grown in contaminated soils, finding low but significant uptake of toxic inorganic arsenic species, supporting stringent soil arsenic standards for food safety and heavy metal certification programs.

This review outlines key soil, crop, and management factors affecting cadmium accumulation in spinach and carrots, emphasizing mitigation strategies relevant to heavy metal certification and food safety programs.

This study analyzed heavy metal contamination in fruits and vegetables from Polish markets, showing that dried products often exceed Cd and Pb limits, with significant implications for food safety monitoring and heavy metal certification programs

Guidance translating heavy-metal science into controls for sweet potato supply chains: risk profile, farm-to-factory remediation, HACCP integration, and verification specs (ICP-MS, sampling, limits) to meet stringent standards and reduce recalls.

Integrated low-temperature biochar, compost, and NPK improved maize yield, nutrient status, SOC, and pH in calcareous soil, with metal-relevant input characterizations informing HTMC compliance.

What was studied?This original study examines heavy metal accumulation in sweet potato irrigated

The study shows heavy metal content in sweet potato skyrockets with gold-tailings admixture, often above food limits; manure moderates some uptake but not enough for safe consumption.
