With the trend towards larger herds during the past decade there has been a marked increase in the number of pipeline milking machines which are cleaned in place and refrigerated farm bulk tanks many of which are cleaned automatically. There is possibly less emphasis on udder washing, and in-line filters to detect mastitis clots may be replacing the foremilk cup. The storage of milk in a bulk tank at 4°C or less from the time of production means that virtually no bacterial multiplication takes place in the milk for at least 24 h. With these changes a reappraisal of the relative importance of the sources of numbers and types of bacteria in raw milk is timely and may contribute to a better understanding of bacteriological problems which can arise with modern methods of milk production.
