Major Mammary Pathogens as Contributors to Total Bacterial Counts in Raw Milk

Bacteria Counts in Raw Milk

There is little doubt that raw milk is the most scrutinized agricultural commodity. Appendix N of the Pasteurized Milk Ordinance requires that all bulk tank milk be tested for beta-lactam antibiotics. This document also sets the regulatory levels for somatic cell counts (SCC) and bacteria levels in raw bulk tank milk. Milk processors are required to perform the regulatory testing. Many progress...

Examination of the behaviour of bacterial pathogens in raw milk

Among recent trends towards less processed foods is a growing consumer demand for raw (unpasteurised) dairy products. In spite of the public health risks and an increased awareness of pathogens in milk, proponents of raw milk consumption are of the view that pasteurisation kills beneficial microorganisms believed to have antimicrobial properties towards pathogens. This study thus aimed to exami...

Psychrotrophic vs. total bacterial counts in bulk milk samples

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...

Monitoring of Foodborne Pathogens in Raw Cow Milk in Tuscany

Raw milk consumption in Italy has increased over the last few years and although raw milk is characterised by cold chain, short shelf-life and the duty of boiling before domestic consumption, it is still considered a hazard. From 2010 to 2013 a monitoring survey of raw milk sold through vending machines was carried out to investigate the occurrence of several foodborne pathogens stipulated in t...
