This research demonstrates that zinc amendments in soil drive the co-selection and spread of antibiotic resistance genes, mediated by mobile genetic elements and changes in microbial communities, emphasizing the need for stringent heavy metal regulation in agricultural certification programs.

Therapeutic zinc oxide therapy in pigs increases MRSA prevalence and persistence without improving growth, highlighting the need for careful regulation of ZnO use to reduce antimicrobial resistance risks in agriculture.

This review found consistent links between antimicrobial and heavy metal use and increased resistance genes in pigs, emphasizing the need for standardized, culture-independent monitoring to inform effective heavy metal certification and regulation in animal production.

This study demonstrates that zinc supplementation in pig farms is strongly linked to the co-selection and spread of antimicrobial and metal resistance genes via mobile genetic elements, emphasizing urgent regulatory needs for heavy metal use in agriculture.

This review elucidates how glutathione orchestrates molecular detoxification of reactive oxygen species and methylglyoxal in plants, offering key insights into metal tolerance and implications for certification and phytoremediation.

This review establishes class 1 integron-integrase (intI1) as a sensitive, practical biomarker for anthropogenic pollution, including heavy metals, supporting its use in heavy metal certification and environmental monitoring programs.

Long-term nickel exposure significantly increased the diversity, abundance, and mobility of antibiotic resistance genes in agricultural soils, emphasizing the need for metal contamination monitoring in certification programs.

Heavy metal pollution significantly accelerates antibiotic resistance by multiple genetic and biochemical pathways. Certification programs must address metal contamination to effectively limit the spread of antimicrobial resistance in agriculture, industry, and clinical domains.

This study quantifies heavy metal contamination in Fujairah urban soils, identifies anthropogenic sources, and assesses ecological and health risks to support the HTMC certification program and urban regulatory compliance.

This study elucidates the role of the glyoxalase system in Group A Streptococcus, revealing its essential function in detoxifying host-derived methylglyoxal and enhancing bacterial survival against neutrophil killing—key insights for heavy metal certification and microbial risk assessment programs.
