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.

This review explores how metals interact with the gut microbiota, impacting host health via the gut-brain axis. It evaluates advanced omic tools for assessment, providing critical insights for refining heavy metal safety evaluations and certification standards.

This review highlights biosorption as an economical, eco-friendly alternative for heavy metal removal, summarizing microbial, algal, fungal, and waste-based biosorbents, their mechanisms, and industrial applications relevant to certification programs.

This study used metagenomics to reveal fungal community diversity in heavy metal contaminated soils, showing lead’s severe impact and identifying tolerant genera and functional genes relevant for bioremediation and certification.

This study demonstrates that chronic exposure to arsenic and cadmium disrupts the gut microbiome and metabolome in mice, notably reducing butyrate producers and altering metabolites linked to metabolic health, providing critical evidence for the importance of rigorous heavy metal certification in consumer safety.
