    Objective: To evaluate the content of heavy metals in roots and leafy vegetables from the wholesale market of Lima in 2023. Methodology: A quantitative, analytical, and cross-sectional approach was used. Samples of potato, carrot, lettuce, and spinach (500g each) were collected from the wholesale market in Lima, Peru, in 2023. AOAC analysis methods were applied for each heavy metal. A 95% confidence level was used to determine whether the concentrations of contaminants exceeded the established limits. The Wilcoxon non-parametric test was used with a p-value of 0 and a significance level of 5%. Results: The statistical test confirmed that the presence of heavy metals was below the established limits. The p-value was 0 at a 5% significance level, confirming that the median concentrations of arsenic, lead, and cadmium in the tested vegetables were lower than the maximum allowed by regulations. Conclusions: The analysis of arsenic, lead, and cadmium content in the roots and leafy vegetables from the wholesale market of Lima, Peru, in 2023 showed that the concentrations were lower than the national regulatory limits. Further studies should be conducted in other areas or in soils contaminated by mining activity, and it is recommended to acquire food from batches sold at the point of origin for comparison.

    The requirement for maximum levels of cadmium in cocoa and derived products established in subsection 3.2.7 of the Annex to the European Union (EU) Regulation No. 488/2014 shall be in accordance with the World Trade Organization (WTO) Sanitary and Phytosanitary (SPS) rules. Thus, through the dogmatic method it is analysed whether it is a SPS measure that affects international trade and if it complies with the basic principles of the SPS Agreement as if the measure: was issued under the sovereign right of the European Union (EU) Member States (MS) to adopt SPS measures, was adopted to protect human life or health, had scientific basis, and does not imply arbitrary or unjustified discrimination.
