In our study, we analyzed 45 real samples from five zones in the heavily industrialized area around Dhaka. We utilized advanced techniques such as graphite furnace atomic absorption spectrometry (GF-AAS), hydride generation (HG)-AAS, and flame (F)-AAS methods to assess the presence of toxic heavy metals (HMs), including Pb, Cd, Cr, As, and Ni, as well as essential trace elements such as Mn, Cu, and Zn, which may become harmful when present at elevated levels. The concentration ranges in poultry meat and egg samples were as follows (mg/kg-fw): Pb (1.215–5.66), Cd (0.01–0.019), Cr (0.199–14.58), As (0.01–0.2), Ni (1.69–10.55), and Mn (0.22–6.47). Furthermore, the poultry feed samples presented varying concentrations (mg/kg): Pb (4.53–6.14), Cd (0.17–0.2), Cr (20.4–516.62), As (0.27–0.39), Ni (35.17–66.06), Mn (11.65–84.39), Cu (2.43–7.09), and Zn (17.38–56.38). Some components (Cr, Ni, and Pb) were found in similar ratios in chicken feed samples and poultry products, indicating that poultry feed is a potential source of such elements in poultry products. Newly identified higher levels of Ni demand further investigation into this sector and how it incorporates the studied components. The mean concentrations of most elements in foods exceeded the maximum allowable concentration (MAC), which indicates that some other sources were involved. Furthermore, the dietary and toxicological assessment highlighted concerns related to Cr, Pb, and Ni exposure, indicating a possible serious toxicological impact (CR index for Cr: 0.0014) on human health. Therefore, it is imperative to acknowledge the potential health risks posed to consumers through chemical exposure to chicken meat and eggs. These issues must be addressed to ensure food safety and protect public health.</div></div>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":"88 8","pages":"Article 100565"},"PeriodicalIF":2.1,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144336647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phage biocontrol has emerged as an effective strategy for controlling foodborne pathogens in various foods. This study examined the efficacy of phage biocontrol in mitigating <em>Escherichia coli</em> O157:H7 contamination in soft wheat milling operations. The findings demonstrated the efficacy of phage applications in reducing <em>E. coli</em> O157:H7 on wheat while maintaining flour quality and sensory attributes. Laboratory tests showed that the phage cocktail reduced <em>E. coli</em> O157:H7 populations by up to 1.3 log CFU/g within 4 h on wheat grains, with reductions correlated to phage concentrations. In mill trials, tempering soft wheat with phage cocktail at three concentrations i.e. 1 × 10<sup>6</sup> PFU/g, 2.5 × 10<sup>6</sup> PFU/g, and 1 × 10<sup>7</sup> PFU/g resulted in significant reductions in populations of a nonpathogenic <em>E. coli</em> O88 strain, ranging from 1.4 to 3.1 log CFU/g, in a dose-dependent manner. Tempering with phage reduced the <em>E. coli</em> populations throughout the milling operation. Two different tempering systems, the DAMPE system and the Bühler Turbolizer, were evaluated. Both systems achieved similar overall reductions, although the DAMPE system showed slightly higher efficacy than the Bühler Turbolizer after 6 h of tempering. Additionally, phage treatments reduced positive samples in straight-grade and patent flours by 15–29%. Importantly, solvent retention capacity and hydration performance of phage-treated flour were unaffected, and sensory tests indicated no changes in flavor, texture, or appearance of baked products, including cookies and pancakes.

A project was launched in 2022 to sample donated venison and to determine if and at what concentration this meat might be contaminated with Pb. Tests for Pb were first conducted by medical radiography (X-ray) of 0.45 kg (1 lb) and 0.91 kg (2 lb) samples followed by subsampling for quantitative analysis using inductively coupled atomic plasma emission spectroscopy (ICP-AES). Among venison packages, 19% (11/ 59) were confirmed to contain metal fragments via radiography and/or Pb via ICP-AES. This includes seven packages with observable metal fragments via X-ray, three packages with suspected metal fragments via X-ray and detected via ICP-AES and one package with no radiographic evidence of Pb, but detected via ICP-AES.
