“…It is clear that there are two important kitchen equipment facilities that can be a target of microbial persistence forms: domestic refrigerators and cutting boards. Different studies have detected foodborne pathogens such as Listeria monocytogenes , E. coli , Yersinia enterocolitica , or S. enterica in the kitchen environment and on the interior surfaces of domestic refrigerators . In a study carried out in USA, Kosa et al .…”

Salmonella and Campylobacter biofilm formation: a comparative assessment from farm to fork

It takes several steps to bring food from the farm to the fork (dining table), and contamination with food-borne pathogens can occur at any point in the process. Campylobacter spp. and Salmonella spp. are the main microorganisms responsible for foodborne disease in the EU. These two pathogens are able to persist throughout the food supply chain thanks to their ability to form biofilms. Owing to the high prevalence of Salmonella and especially of Campylobacter in the food supply chain and the huge efforts of food authorities to reduce these levels, it is of great importance to fully understand their mechanisms of persistence. Diverse studies have evaluated the biofilm-forming capacity of foodborne pathogens isolated at different steps of food production. Nonetheless, the principal obstacle of these studies is to reproduce the real conditions that microorganisms encounter in the food supply chain. While there are a wide number of Salmonella biofilm studies, information on Campylobacter biofilms is still limited. A comparison between the two microorganisms could help to develop new research in the field of Campylobacter biofilms. Therefore, this review evaluates relevant work in the field of Salmonella and Campylobacter biofilms and the applicability of the data obtained from these studies to real working conditions. © 2018 Society of Chemical Industry.

“…Until date, there are no reports of yeasts, isolated from freezers, and few are reporting their isolation from refrigerators. Yeasts have been isolated from plastic refrigerator vegetable compartments, rubber seals, walls and water dispensers [43,44]. Candida species have been isolated most frequently, with Pichia kudriavzevii prevailing in refrigerator air [45].…”

Candidiasis is one of the common fungal opportunistic infections, usually associated with diverse Candida species. Candida albicans, C. glabrata complex, C. parapsilosis complex, C. tropicalis and C. auris are often identified in affected patients. Candida parapsilosis sensu stricto is an emerging cause of hospital-acquired Candida infections, predominantly in Southern Europe, South America and Asia. Home environment is a less known source of infection despite frequent isolation of C. parapsilosis from kitchen surfaces and household appliances such as dishwashers, washing machines and refrigerators. C. parapsilosis is one of the first colonisers of novel dishwashers and a member of stable fungal communities on rubber seals worldwide in concentrations up to 10 2 CFU/cm 2. It colonises also drawers for detergents in washing machines and drainage channels in refrigerators. Tap water and groundwater act as vector for entrance of C. parapsilosis in the indoor environments. Within C. parapsilosis, four clinically relevant phenotypes can be distinguished. Experimental data on the prevalence of C. parapsilosis isolates phenotypes, obtained from indoor environments, will be presented. Smooth phenotype prevails in dishwashers and washing machines, while crepe and crater dominate in water. In conclusion, the ability to colonise diverse environments and accordingly switch phenotypes defines C. parapsilosis as a versatile, domestic environment-related opportunistic pathogen.

“…One study mapped the microbiota of kitchen surfaces [53], while others have investigated the impact of food preparation hygiene and cleaning [54,55]. In addition to the microbiota of food-preparation surfaces, the ambient bacterial levels of food storage areas such as refrigerators are also of note [56]. Several studies have looked at meat storage over time and under various conditions via pyrosequencing-based measures of the associated microbial communities [57–59].…”

High-throughput, ‘next-generation’ sequencing tools offer many exciting new possibilities for food research. From investigating microbial dynamics within food fermentations to the ecosystem of the food-processing built environment, amplicon sequencing, metagenomics, and transcriptomics present novel applications for exploring microbial communities in, on, and around our foods. This review discusses the many uses of these tools for food-related and food facility-related research and highlights where they may yield nuanced insight into the microbial world of food production systems.
