Hospitalized patients had significantly higher C-reactive protein levels compared with discharged patients (median 76.0 vs. 26.1 mg/L; p = 0.002). Stool cultures, performed in a subset of patients, identified pathogenic organisms in 37.8% of samples, predominantly Salmonella spp. Microbiological analysis of food samples demonstrated multimicrobial contamination, including Salmonella spp., Listeria monocytogenes, Bacillus cereus, and coagulase-positive Staphylococcus. This outbreak represents one of the largest reported chicken döner-associated foodborne events worldwide and highlights the substantial health care burden posed by contaminated ready-to-eat poultry products.

The risk of foodborne infections has increased with the globalization of food supply chains. Foodborne parasites are an emerging public health concern, posing particular risks for populations consuming raw or minimally processed produce. This study investigated parasitic contamination in raw vegetables used to prepare salads sold in Corum Province, Türkiye. From October 2020 to March 2021, 80 locally produced vegetable samples were collected from the central wholesale market. After standardized washing and centrifugation, sediments were examined microscopically, and DNA was extracted for molecular detection of Cryptosporidium, Giardia, Entamoeba, and Blastocystis using polymerase chain reaction (PCR) and sequencing. Overall, 22/80 samples (27.5%) were positive for parasites by both microscopy and PCR. The highest percentages of total samples contaminated were observed in lettuce (8.8%), parsley (6.3%), and arugula (5.0%). Microscopy revealed 13 protozoan cysts and 10 helminth eggs, while PCR identified Blastocystis spp. (15%), Cryptosporidium spp. (3.8%), and Giardia spp. (1.3%). Sequence analysis confirmed Blastocystis ST1, Giardia duodenalis Assemblage A, and Cryptosporidium parvum, all with recognized zoonotic potential. These findings suggest that fresh vegetables in Türkiye may contribute to zoonotic transmission, emphasizing the importance of improved produce hygiene and monitoring. Our findings highlight the urgent need for preventive measures to reduce foodborne parasitic infections in consumers.","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":" ","pages":"15353141261440902"},"PeriodicalIF":1.9,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147689154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have suggested that improving food safety culture in restaurants (i.e., shared values, beliefs, and norms about food safety) is an important way to reduce foodborne outbreaks. However, we know relatively little about the connections between food safety culture and food safety outcomes in restaurants. To bridge these gaps in knowledge, state and local health department staff with CDC's Environmental Health Specialists Network (EHS-Net) conducted a study in which they interviewed managers and administered written surveys to food workers in 321 restaurants across eight EHS-Net jurisdictions. Data on restaurant characteristics (e.g., the existence of food safety policies) were collected through interviews with restaurant managers. Data on food worker characteristics (e.g., food safety knowledge) were collected through a worker survey. The survey also assessed worker beliefs about food safety in their restaurants (i.e., food safety culture). Analyses showed that several restaurant characteristics, including the existence of food safety policies and methods for monitoring policy implementation, were significantly and positively associated with workers' perceptions of their restaurant's food safety culture. The worker characteristics of having had food safety training and possessing food safety knowledge were also significantly and positively related to worker food safety culture beliefs. These findings suggest that management actions, such as providing food safety training, implementing food safety policies, and monitoring compliance with those policies, are associated with a strong food safety culture.","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":" ","pages":"223-231"},"PeriodicalIF":1.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12353076/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cohabitants' anal swabs (3), milk powder (1), a feeding bottle (1), and kitchen items (3) were collected and screened for C. jejuni. Antimicrobial susceptibility testing was conducted, and whole genome sequencing was performed for genetic analysis, including whole genome multilocus sequence typing (wgMLST), single-nucleotide polymorphism, antimicrobial resistance (AMR) and virulence gene profiling. As a result, three C. jejuni strains were isolated from the infant, the infant's grandmother, and the feeding bottle. The results revealed that the three C. jejuni isolates were clonally related, sharing minimal genetic differences. The infant's grandmother, who had slaughtered a live chicken 4 days before the infant's illness, was identified as the likely source of transmission. AMR profiles showed resistance to fluoroquinolones and cephalosporins. The three isolates were found to carry the blaOXA-184 gene and a chromosomal mutation in gyrA (T86I). Additionally, 69 virulence genes were identified in all isolates, including those associated with adherence (4), glycosylation system (23), motility and export apparatus (38), cytolethal toxin (3), and invasion (1).

This parasite is frequently located in the gastrointestinal tract, and previous reports have described complications such as acute appendicitis, Meckel's diverticulitis, pancreatitis, cholecystitis, liver abscess, intestinal obstruction, and perforation. Intestinal perforation due to parasitic diseases is a rare complication. Surgical complications associated with T. saginata are uncommon, with few reported cases of bowel perforation. Here, we present the case of a 69-year-old female who was admitted to the emergency department with acute abdominal symptoms. She had experienced abdominal pain and vomiting for 15 days. Her symptoms were accompanied by abdominal distension, reduced bowel movements, and loss of appetite. On physical examination, she had diffuse abdominal tenderness, guarding, and rebound tenderness, raising suspicion of peritonitis. Laboratory tests revealed a white blood cell count of 8,000/mm3 and an elevated C-reactive protein level of 501 mg/L, indicating an ongoing inflammatory response. Imaging revealed free intra-abdominal air and fluid, suggesting gastrointestinal perforation. During emergency surgery, a perforation in the upper rectum was identified and resected. Pathological examination confirmed the presence of T. saginata eggs in the intestinal wall. Postoperatively, the patient recovered well and was discharged on the sixth day. This case underscores the need for heightened awareness of parasitic infections as potential causes of acute abdominal conditions. Proper diagnosis and prompt surgical intervention are crucial in managing complications associated with T. saginata. Preventive measures, including thorough cooking of beef and improved sanitation, are essential to reduce the incidence of such infections.","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":" ","pages":"274-278"},"PeriodicalIF":1.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144001745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to explore the impact of EfEV supplementation on the intestinal barrier function and microbiota composition in piglets. In vitro intestinal porcine epithelial cell J2 (IPEC-J2) cell culture experiments have shown that supplementation with EfEV significantly enhanced cell viability, increased the activity of the antioxidant enzyme, promoted cell proliferation, and inhibited autophagy. In vitro, fecal culture experiments demonstrated significant increases in OD630 and the contents of acetic aid, butyric acid, and isovaleric acid, and decreases in valeric acid following EfEV supplementation. Furthermore, EfEV supplementation altered the diversity and composition of the intestinal microbiota. It significantly reduced levels of Escherichia-Shigella at the family level, while increasing the abundance of beneficial microorganisms, including [Eubacterium]_eligens_group, unidentified_Mitochondria, Lachnoclostridium. In conclusion, EfEV plays a pivotal role in inhibiting pathogens growth, enhancing the production of metabolites such as acetic acid and butyrate acid, providing energy for microorganisms, and protecting the intestinal barrier.","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":" ","pages":"260-267"},"PeriodicalIF":1.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143647883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Northern China has a large-scale fur animal farming industry. Although there have been related studies, systematic data remain lacking. In this study, a total of 871 fecal samples were collected from fur animals in Shandong, Hebei, Liaoning, Jilin, and Heilongjiang provinces. Using nested polymerase chain reaction, 75 Cryptosporidium-positive samples were detected, and the overall infection rate was 8.61%. The infection rates ranged from 4.23% to 16.81% across different provinces, with the highest rate was observed in Shandong (16.81%, 19/113), followed by Jilin (15.07%, 11/73). Additionally, foxes (15.06%, 53/352) showed a higher infection rate compared with mink (4.55%, 13/286) and raccoon dogs (3.86%, 9/233), suggesting that foxes may be more susceptible. Four species/genotypes were identified: Cryptosporidium canis (n = 66), Cryptosporidium meleagridis (n = 1), Cryptosporidium parvum (n = 1), and mink genotype (n = 7). Among these, C. parvum and C. meleagridis were found in raccoon dogs and foxes, respectively, while the mink genotype was detected only in mink.
