An increase in the export of UHT (Ultra Heat Treated) milk to Asian markets is potentially worth millions of dollars to the dairy inmdustry. This increase however, relies on the shelf life of UHT products being extended to nine months. Spoilage of UHT milk can be caused by bacterial spores which originate on-farm and are resistant to processing. Expansion in the UHT market therefore relies on a continued reduction in the number of these spores getting into raw milk. Caroline Love, Ian Bell and Martin Robertson report on the sources of spores entering milk on-farm and the control methods available.
