(1) Raw milk, at the time of its acceptance at a treatment establishment, unless treated within 4 hours of acceptance, shall be cooled to a temperature not exceeding 6°C and maintained at that temperature until heat-treated.
(2) Where raw cows' milk is not treated within 36 hours of acceptance at a treatment establishment, a further test shall be carried out on such milk before it is heat-treated.
