The Ontario dairy industry takes great pride in providing a high quality food product to the consuming public. Milk and milk products are an important part of the daily diet of most Ontario residents. Bacterial contamination of raw milk has a major negative impact on milk quality (Reed and Grivetti, 2000). Even though most milk is pasteurized prior to consumption, raw milk is consumed by some farming families and is used to manufacture some food products (Hegarty et al, 2002). One potential source of bacterial contamination of raw milk bacteria is the water used to clean the milking and storage equipment (Jayarao and Wang, 1999). The Canadian Quality Milk (CQM) program has established criteria for water quality on dairy farms. Initial testing has suggested that as many as half of Ontario dairy farms do not currently meet these water quality standards. Test results suggest that while some water may be contaminated at its origin, there is also significant contamination that occurs in the "plumbing", and is expressed as an elevation in bacteria counts at the point-of-use. The Dairy Farmers of Ontario (DFO) have begun a water quality-testing program, intended to decrease the risk of bacterial contamination of raw milk. The net benefit to the dairy industry will be to evaluate and document the improvement in raw milk quality attributable to compliance with the CQM program. The objective of the current study was to identify areas of high risk of wash water contamination and to investigate the relationship between bacteria-contaminated wash water and elevated Bactoscan bacteria counts in raw milk.

The Ontario dairy industry takes great pride in providing high quality milk products to the consuming public. Milk and milk products are an important part of the daily diet of most Ontario residents. Bacterial contamination of raw milk has a major negative impact on milk quality. Even though most milk is pasteurized prior to consumption, raw milk is consumed by some farming families and is used to manufacture some food products. Dairy Farmers of Ontario have required installation of Time Temperature Recorder's (TTR's) on all Ontario dairy farms, with the intention of preventing elevated bacteria levels in raw milk under the Canadian Quality Milk Program. The TTR has two sensors, one in the bulk tank that monitors the raw milk temperature and one in the pipeline to monitor wash water temperature during the wash cycle. The objective of this study was to evaluate the impact of TTR's on the bacterial content of raw milk and the loss of (dumped) bulk tank milk on Ontario dairy farms and to summarize the occurrences of the different TTR alarms.

This paper describes AIMS which is a flexible manufacturing system, formally opened at Rolls-Royce plc, Derby, in January 1986, for the production of aero engine turbine and compressor discs. These are the high-value, rotating components which require structural integrity together with a high degree of precision during the manufacturing process. The prime objective for the project was to reduce the value of work-in-progress to an extent which would enable cost savings in the inventory to finance the project in its first full year of operation. The paper details its concept strategy and examines the equipment requirements, justification and benefits of the capital investment. It also describes planning and implementation aspects, together with computer hardware/software support.
