Native probiotics restored autophagy gene expression impaired by nickel in mice, confirming the gut–brain axis’s role and highlighting probiotic supplementation as a strategic tool for heavy metal mitigation in certification programs.

This review synthesizes evidence on how heavy metals alter gut microbiota and metabolites, emphasizing implications for certification programs and the potential of probiotics as protective interventions.

Lead exposure disrupts gut microbiota, amplifying neurological and behavioral risks associated with autism spectrum disorder. Certification programs must address both direct and microbiome-mediated effects, emphasizing low exposure limits and considering microbiota health in risk management.

This study found that many commercial baby food jars contain toxic metals above EU safety limits, posing risks to infants. These findings are critical for heavy metal certification programs, which must enforce stricter controls to ensure product safety and regulatory compliance.

This study assessed nickel levels in Polish cereal grains and cereal-based products, finding that consumer exposure remains well below health risk thresholds. The results support effective risk management and could inform future heavy metal certification standards.

This review demonstrates that specific probiotic strains can effectively bind and remove heavy metals and toxins from food and water, offering a promising tool for heavy metal certification programs and industry safety practices.

Arsenic concentration in infant formulas and first foods poses significant exposure risks to infants, primarily due to the prevalence of toxic inorganic arsenic, especially in rice-fortified and non-dairy products. Stringent certification and speciation are essential for infant food safety.

This review establishes iron-driven ferroptosis as a key mechanism in neurodegenerative diseases. It details how iron dyshomeostasis, facilitated by blood-brain barrier breakdown, catalyzes neuronal death, presenting critical implications for developing heavy metal certification standards focused on mitigating iron-mediated toxicity in the brain.

Metagenomic analysis revealed that microbial communities in heavy metals-contaminated soils lose diversity but adapt by enriching resistant taxa. Core community structure persists, with key shifts in dominant bacteria and archaea, providing essential insights for soil health assessment and certification in contaminated environments.
