Aluminum (Al) showed the highest concentrations, while strontium (Sr) and barium (Ba) were moderate; other elements (molybdenum (Mo), chromium (Cr), lead (Pb), cadmium (Cd), thallium (Tl), cobalt (Co), arsenic (As)) were low; and nickel (Ni) was undetected. All dishes complied with GB 2762-2022 limits. Although seven dishes showed mild-to-moderate single-factor contamination, Nemerow indices confirmed safe levels (Pc &lt; 0.7). Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) indicated that processing methods drove contamination profiles, with deep-fried products accumulating higher metal levels than stir-fried or boiled ones. While non-carcinogenic risks were acceptable for adults, children showed higher susceptibility with Total Target Hazard Quotients (TTHQ) values nearly double those of adults, exceeding safety thresholds in certain dishes primarily due to As and Cr. Carcinogenic risks for hexavalent chromium (Cr(VI)) and inorganic arsenic (iAs) were acceptable (1 \u00d7 10\u22126 to 1 \u00d7 10\u22124) for 32 dishes. After speciation-based recalibration, the remaining three dishes also fell within safe limits. Overall, exposure risks are low, though specific deep-fried products warrant monitoring.<\/jats:p>","DOI":"10.3390\/foods15010073","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T02:07:58Z","timestamp":1766714878000},"page":"73","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Analysis of Elemental Concentrations and Risk Assessment of Prepared Livestock and Poultry Meat Dishes Sold in Zhejiang Province"],"prefix":"10.3390","volume":"15","author":[{"given":"Chenyang","family":"Zheng","sequence":"first","affiliation":[{"name":"Zhejiang Provincial Center for Disease Control and Prevention, Hangzhou 310051, China"},{"name":"NHC Specialty Laboratory of Food Safety Risk Assessment and Standard Development, Hangzhou 310051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Tan","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Center for Disease Control and Prevention, Hangzhou 310051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengyan","family":"Hu","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Center for Disease Control and Prevention, Hangzhou 310051, China"},{"name":"NHC Specialty Laboratory of Food Safety Risk Assessment and Standard Development, Hangzhou 310051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingshun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Center for Disease Control and Prevention, Hangzhou 310051, China"},{"name":"NHC Specialty Laboratory of Food Safety Risk Assessment and Standard Development, Hangzhou 310051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Tang","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Center for Disease Control and Prevention, Hangzhou 310051, China"},{"name":"NHC Specialty Laboratory of Food Safety Risk Assessment and Standard Development, Hangzhou 310051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,25]]},"reference":[{"key":"ref_1","unstructured":"People\u2019s Daily Online Research Institute (2023, July 11).
