In pregnant women, listeriosis can cause miscarriage, stillbirth, and other serious complications. Manufacturing guidelines are created with the intention that frozen vegetables will be cooked prior to consumption. However, consumers may prepare and eat frozen vegetables without prior cooking. Therefore, it is necessary to assess behaviors that could be risky for <em>L. monocytogenes</em> exposure. A 10-question online survey was distributed to women between the ages of 18–54 to investigate frozen vegetable consumption behaviors. The prevalence of uncooked frozen vegetable consumption, reading preparation instructions, and listeriosis knowledge was assessed. Data were analyzed using logistic and ordered logit regression. Of 1,001 complete responses, 531 (53%) indicated that they consumed frozen vegetables in the past week, and of those 35.6% (<em>n</em> = 189) indicated that they consumed frozen vegetables without prior heating. Women who had not heard of listeriosis and had not read preparation instructions had significantly higher odds of uncooked frozen vegetable consumption (Odds Ratio (OR): 2.30, 95% Confidence Interval (CI): 1.48, 3.55; OR: 1.85, 95% CI: 1.13, 3.01, respectively). These results will guide future research on safe food handling practices for frozen vegetable products. The findings support the need for updating public health guidelines to include frozen vegetables as foods that are risky for listeriosis in pregnancy. Additionally, these findings have implications for future research to inform food policy governing labeling regulation on frozen vegetable products to reflect current consumer behavior.</p></div>","PeriodicalId":15903,"journal":{"name":"Journal of food protection","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0362028X24000991/pdfft?md5=3fb00a02d6655f7115088d23d45ba435&pid=1-s2.0-S0362028X24000991-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141317520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interviews and direct observations were carried out during the assessment of hygiene and handling practices at six farms designated A to F. Microbiological criteria of the following six microbiological parameters: Total Bacterial Counts (TBCs), Coliform Counts (CCs), Total <em>Escherichia coli</em> Counts (TECs), <em>Salmonella</em> spp., <em>Listeria monocytogenes</em> and <em>Klebsiella pneumonia</em>, were used to determine contamination level (CL) at four different critical sampling locations (CSLs). The CSLs were raw milk (CSL1), cultured milk (CSL2), milkmen’s hands (CSL3), and milking containers (CSL4). The microbiological criteria of the six microbiological parameters were used to score CLs as: intolerable (0), poor to average (1), average (2), and good (3). MSLPs at each CSL for the six farms were computed based on the CL scores to a maximum score of 18. A total of 192 samples were collected and analyzed. <em>Salmonella</em> spp. and <em>L. monocytogenes</em> were not detected at all the CSLs. All the farms failed to achieve a maximum MSLP score of 18 at all the CSLs. The relationship between MSLPs and hygiene and handling practices was tested using point-biserial correlation coefficients. The correlation study revealed that handling and hygiene practices (such as the duration between milking and storage, the type of milking container utilized at farms, the frequency of cleaning the milking parlor, the water source for hand and equipment washing, and the use of hand sanitizers) generally influenced the MSLPs on the farms.

Poultry represent one of the main sources of <em>Campylobacter</em> organisms.

The <em>C. jejuni</em> and <em>C. coli</em> isolated from poultry and poultry meat were screened for the presence of virulence determinants like <em>cad</em>F, <em>fla</em>A, <em>cdt</em>B, and <em>wla</em>N gene. The screening for <em>wla</em>N gene is crucial in view of the fact that most patients with Guillian Barre’s (GB) syndrome with a preceding history of diarrheal illness have been found to harbor <em>wla</em>N gene−positive <em>C jejuni</em> strains. Out of the 200 samples comprising poultry meat and cloacal swabs, 21.5% of samples were found to harbor <em>Campylobacter</em> spp. of which 2.5% were <em>Campylobacter jejuni</em>, and 19% were confirmed as <em>Campylobacter coli</em>.
