LPT 311: Milk and Milk Products Technology (1+1)

SAMPLING FOR BACTERIOLOGICAL EXAMINATION

• 10 ml of milk is taken in a previously sterilized bottle fitted with a sterlized glass stopper.
• Only sterilized equipments must be used in collecting samples for bacteriological examination.
• Samples are packed in ice. No antiseptics should be used.
• Since largest number of bacteria is found in the cream layer at the top of the bulk, milk should be mixed well before collecting the sample.
