The application describes conveyors suitable for use e.g. in food processing apparatus, with particular procedures and arrangements for decontaminating the surface (12) of the conveyor (10). The conveyor surface is subject first to a mechanical cleaning e.g. by spraying of liquid followed by brushing in a rinse/clean unit (120). This displaces gross debris from the conveyor surface. In a second step the surface is subjected to UV irradiation to sterilise the cleaned surface. This UV irradiation may be by means of banks (200) of UV lamps between which the conveyor passes. Detectors (165, 166) for residual organic material may be used to monitor the cleanliness of the surface.
