e objective of the study was to determine psychrotrophic bacteria counts (PBC) and total bacterial counts (TBC) in bulk milk samples collected during a longer period (1999 to 2000). Two sets of samples were analysed. Set 1, including samples collected in three herds, was analysed by the Central Laboratory at České Budějovice. TBC was determined using the apparatus Bactoscan, and PBC by culture...

The purpose of this research was to assess the hygienic properties of commercially available dairy foods. The products surveyed included liquid milks (pasteurized and UHT-treated), cultured dairy products (kefir, cultured buttermilk, sour cream, yogurt, probiotic fermented milks), cheeses (quarg products, soft, semi-hard, hard, and extra hard cheeses made from bovine, caprine, and ovine milk), ...

Microbiological quality control of 13 pollen samples purchased from local markets and 2 other samples provided by apiarists was investigated. TAMC ranged from 3.00 to 5.48 Log CFU/g. TMYC was between 2.3 and 6.99 Log CFU/g. Staphylococcus aureus was recovered with high density in 14 samples (up to 8.32 Log CFU/g) and Enterobactericeae count ranges from 4.18 to 8.018 Log CFU/g. Moreover, Salmone...

A fundamental limiting factor in the assessment of microbial quality of waters, and especially drinking water, is often the very low number of each organism present. Therefore, it is important to note that most microbiological procedure consists of: concentration/enrichment, detection and quantification (Table 8.1). A consequence of this multi-step approach is that technological advancement of ...

The consumption of fresh nopal cactus juice is widely popular among health-conscious consumers in Mexico. The juice is prepared from fresh cladodes that have only been rinsed with tap water and are not subjected to a pasteurization or terminal bacterial reduction process. The aim of this study was to evaluate the microbial quality of commercially available fresh juices (n = 162) made with nopal...

Municipal green waste (MGW) has significantly increased with the development of urban areas, and its utilization by composting is a good alternative to solve problem. This paper presents results from quality assessment two industrial composts (from facility regional nonhazardous landfill) based on their physicochemical properties, hygienic safety (microbiological parameters), fertilizing potent...

Maintenance of the microbiological quality of water has been used as an important means of preventing waterborne disease throughout the twentieth century. The commonest microbiological tests done on water are for coliforms and Escherichia coli (or faecal coliform). This paper reviews the legislative and other guidance for microbial standards in drinking and bathing waters and considers evidence...
