This study analyzed total and bioaccessible aluminum in cereal-based baby foods, finding low health risk due to low bioaccessibility, supporting the use of refined exposure assessments for heavy metal certification.

This study quantified total and bioaccessible aluminium in Brazilian infant foods, revealing that some products, especially soy-based drinks, can lead to aluminium exposure exceeding safety thresholds, highlighting the need for certification programs to address both total and bioaccessible heavy metal content.

Bradyrhizobium dominates heavy metal-contaminated soils at SRS, correlating with uranium and nickel levels, making it a key genus for bioremediation and certification programs targeting environmental restoration and risk management.

This review reveals a critical bidirectional relationship: heavy metals disrupt gut microbiome diversity and function, while the microbiome modulates metal toxicity. These findings suggest microbiome analysis could become a powerful tool for biomonitoring within heavy metal certification programs for food safety.

This review highlights how probiotics, especially Lactobacillus and Bifidobacterium strains, can detoxify heavy metals, offering a promising, science-backed addition to heavy metal certification programs.

This study identified microbial and genetic biomarkers linked to cadmium accumulation in two rice cultivars, using metagenomics and machine learning. Findings offer actionable insights for heavy metal certification programs to predict and mitigate Cd uptake in rice.

This review highlights digestate’s potential as a sustainable agricultural input, emphasizing its nutrient value and prebiotic properties, but warns that variable heavy metal content and lack of regulation demand rigorous monitoring and certification for safe, long-term use.

Lead isotope analysis in French children enables precise identification of exposure sources in a third of cases with moderate blood lead, providing critical guidance for heavy metal certification and targeted remediation.

This study assessed heavy metal content in popular fruit juices in Southeastern Nigeria, finding all tested samples well below regulatory limits. Results support robust certification and highlight the need for regular monitoring.
