A total of 112 carcasses (average weight of 135.7 ± 18.5 kg) were tested (14 per treatment and control). High steam pressure significantly reduced microbial counts on the carcass surface, with reductions ranging from 0.22 to 2.04 log CFU/cm², while the control treatment achieved only 0.18 log CFU/cm². Steam pressure had a stronger influence on microbial reduction than contact time (<i>p</i> &lt; 0.05). The evaluation of loin muscle color showed no negative effects, with all samples remaining within acceptable commercial standards. These results support the use of steam pressure as an effective hygienic-sanitary intervention in pig slaughterhouses, capable of reducing surface contamination without compromising meat quality.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 4","pages":"303 - 310"},"PeriodicalIF":1.7,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145533308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite recent advancements, alternative detection methods are still needed to mitigate the impact of <i>Salmonella</i> and improve its monitoring in complex food matrices. In this study, we present a simple and cost-effective approach for the preliminary detection of <i>Salmonella</i> in liquid foods such as milk and carrot juice. Gold nanoparticles (AuNPs) were synthesized and functionalized by physical adsorption of a specific anti-<i>Salmonella</i> aptamer onto their surface. For detection, aptamer-functionalized AuNPs were incubated with serial dilutions of <i>Salmonella</i> in buffer, milk, and carrot juice samples, and colorimetric changes were recorded visually and by Ultraviolet-visible spectroscopy. The results were compared with those obtained by standard polymerase chain reaction (PCR) and culture methods. Optimal aptamer adsorption was achieved in 0.01 M MES buffer containing 200 mM NaCl at pH 5.8. Transmission electron microscopy characterization demonstrated that the functionalized AuNPs were stable against salt-induced aggregation and maintained good dispersion. The zeta potential increased to − 27 mV, indicating successful aptamer stabilization on the AuNP surface. The aptamer-functionalized AuNPs were evaluated as plasmonic aptasensors for <i>Salmonella</i> detection in both buffer and real food samples. The sensor exhibited a sensitivity of 400 CFU/mL with a linear detection range from 10³ to 10⁷ CFU/mL. High specificity was observed, with a 5-fold greater response to <i>Salmonella</i> compared to other tested bacteria, including <i>Escherichia coli</i>,<i> Staphylococcus aureus</i>,<i> Bacillus cereus</i>,<i> Citrobacter freundii</i>,<i> and Proteus mirabilis.</i> In field samples, the aptasensor demonstrated promising sensitivity, specificity, and accuracy, ranking third after PCR and cell culture methods.

This study aims to evaluate the antibacterial and antibiofilm effects of carvacrol encapsulated within a nanoemulsion against <i>S. aureus</i>. The minimum mitigation concentration, bacterial growth curves, and cell membrane characteristics were the key parameters examined. Carvacrol nanoemulsions demonstrated superior antibacterial activity compared to pure carvacrol, with a minimum inhibitory concentration of 0.125 mg/mL. Remarkable leakage of intracellular components such as nucleic acids, proteins, and alkaline phosphatases was noted following the exposure of <i>S. aureus</i> to carvacrol nanoemulsions, thereby suggesting significant impairment of the integrity of bacterial cell membranes and cell walls. Carvacrol nanoemulsions effectively disrupted the biofilm formation process in 96-well microtiter plates, and successfully eradicated mature biofilms of <i>S. aureus</i> at minimum concentrations of 0.25 mg/mL and 0.5 mg/mL, respectively. A similarly robust antibiofilm effect of carvacrol nanoemulsions was also achieved on stainless steel surfaces in a dose- and time-dependent manner. This was likely due to the suppression of bacterial surface hydrophobicity. This study underscores the potential application of carvacrol nanoemulsions as a means to combat <i>S. aureus</i> in both planktonic and biofilm states, contributing to microbial food safety control.</p></div>","PeriodicalId":622,"journal":{"name":"Journal of Consumer Protection and Food Safety","volume":"20 4","pages":"357 - 369"},"PeriodicalIF":1.7,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145533216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the impact of the husbandry system (conventional/organic) on visual cleanliness and microbial status was examined. During unloading, 20 pig delivery batches were visually assessed. TVC and Salmonella were examined in the lairage and after singeing/flaming. Even pigs with high initial visual and microbial contamination showed TVC levels comparable to cleaner pigs after singeing/flaming. Comparing mean TVCs between husbandry systems, no significant differences were observed. Salmonella was detected only on pig skin sampled in the lairage (3%, 4/120).

We aimed to quantify chlorpyrifos-ethyl (CE) and chlorpyrifos-methyl (CM) residues in clementines and compare compliance with Moroccan Maximum Residue Limits (0,3 mg kg⁻¹) between fruit destined for export and local markets. During the 2018–2019 harvest, 12 composite samples (each weighing 1 kg) were collected: six from conditioning stations targeting international markets and six from regional markets serving local consumers in Berkane Province. Residues were extracted following EN 123932 (2013) and analyzed by gas chromatography with nitrogenphosphorus detection (LOD = 0.005 mg kg⁻¹; LOQ = 0.01 mg kg⁻¹). Method validation yielded recoveries of 85–110% and an R² value of 0.999. Data normality was checked (Shapiro–Wilk); group means were compared by Welch’s test (α = 0.05), and effect size was reported with Cohen’s d. CE was detected in 83% (5/6) of localmarket samples, with four of six samples (66%) exceeding the Moroccan maximum residue limit of 0.3 mg kg⁻¹ (mean ± SD = 0.70 ± 0.61 mg kg⁻¹). In contrast, CE occurred in two of 6 (33%) of export samples, all of which were below the MRL (0.05 ± 0.04 mg kg⁻¹). CM was present in 3 samples (25%) yet remained within legal limits. The difference in CE levels between supply chains was significant (t = 3.14, p = 0.010; Cohen’s d = 1.2). Local market clementines exhibit markedly higher CE exceedance than export fruit, implying weaker domestic enforcement of pre-harvest intervals.

The method was validated to estimate the residues of the insecticides in broccoli according to SANTE. The limit of quantification of the method for lambda-cyhalothrin and novaluron was 0.010 mg/kg and the method was found to be accurate and precise. The dissipation of lambda-cyhalothrin and novaluron residues in broccoli was in accordance with the first-order kinetic model with half-life of 1.525–1.930 days and 1.678–2.170 days, respectively. The residues of both insecticides were not detected in soil samples at harvest. The pre-harvest interval of 8–12 days for lambda-cyhalothrin and 12–17 days for novaluron was suggested. The proposed maximum residue limits (MRLs) of 0.9–1.5 and 3 mg/kg for lambda-cyhalothrin and novaluron were calculated using the Organisation for Economic Co-operation and Development MRL calculator. The dietary risk assessment showed that the acute and the chronic hazard quotient were less than 1 for lambda-cyhalothrin and novaluron.
