Analysis on Foodborne Pathogen Contamination of Food Samples in Longnan City from 2013 to 2022.

The objective was to determine the prevalence of foodborne pathogens in food in Longnan City, Gansu Province, China. In this research, we conducted tests on baked foods, catering foods, meat, and fruits and vegetables sold in supermarkets, farmers' markets, restaurants, retail stores, street stalls, and school canteens from 2013 to 2022. We analyzed the variety of foodborne pathogens (, , , and diarrheagenic ) in different sites and food types.

Simultaneous Determination and Exposure Assessment of Antioxidants in Food-Contact Plastic Materials by HPLC-MS/MS.

Antioxidants are widely used to prevent oxidative degradation of food-contact plastics materials. However, when plastic products come into contact with food, antioxidants may contaminate food. Herein, twenty-three kinds of possible antioxidants were monitored in 257 products of seven polymers.

N-nitrosamines in Qingdao dried aquatic products and dietary risk assessment.

N-nitrosamines are human carcinogens commonly present in dried aquatic products. A method of gas chromatography - mass spectrometry combined with steam distillation was developed for the determination of 9 N-nitrosamines in dried aquatic products in Qingdao, China, with which 300 samples of fish, squid, shrimp and sea cucumber collected from Qingdao were analysed. A health risk assessment was conducted based on determined levels of N-nitrosamines by using estimated daily intake and slope factors.

Influence of postnatal polycyclic aromatic hydrocarbon exposure on the neurodevelopment of toddlers at the age of 12 months.

Objectives: To investigate the possible influence of polycyclic aromatic hydrocarbons (PAHs) exposure on neurodevelopment of toddlers at the age of 12 months.

Methods: Totally 306 subjects were recruited from the Qingdao Birth Cohort established in 2014. PAH-DNA adducts in toddlers' umbilical cord blood samples, hydroxyl-PAH metabolites in their urine samples and the developmental quotients (DQs) were measured.

Occurrence and Identification of Pathogenic Contaminants in Common Seafood Available in a Chinese Traditional Market in Qingdao, Shandong Province.

The investigation of the causative agents for foodborne diseases and subsequent development of preventive steps to control the outbreak and related economic loss is the basic goal and priority of a rational food safety program. The entero-pathogenic spp., which are Gram negative bacteria inhabiting estuarine ecosystems, are the major cause of foodborne illness associated with the consumption of raw or undercooked contaminated seafood or shellfish.

Genetic characterization of emerging coxsackievirus A12 associated with hand, foot and mouth disease in Qingdao, China.

To characterize the genetic properties of coxsackievirus A12 (CVA12) strains isolated from hand, foot and mouth disease (HFMD) patients in Qingdao during 2008-2011, the complete genome and VP1 coding region were sequenced and analyzed. Phylogenetic analysis showed that all strains from China clustered into three different branches, suggesting multiple lineages of CVA12 co-circulating in Asia. Sequence analysis indicated a monophyletic group only when the P1 region was examined, indicating possible recombination between CVA12 and other HEV-A serotypes.
