Study Notes

Microbial Contamination in Raw Milk Transport

Poor hygiene practices during collection, including unclean equipment and containers, can significantly increase microbial contamination.
Fluctuations in temperature during transport, particularly if milk is not kept at appropriate refrigeration levels, foster the growth of harmful microbes.

Primary Source of Microbial Contamination

The main source of microbial contamination during collection originates from the udder of the cow, as well as the equipment used in the milking process.

Minimizing Microbial Contamination in Storage

Regular cleaning and sanitization of storage tanks and equipment can help reduce microbial growth in stored raw milk.
Maintaining consistent refrigeration temperatures is crucial to inhibit microbial proliferation in stored milk.

Role of Transport Personnel

Transport personnel are vital in maintaining the quality of raw milk; their adherence to hygiene and safety protocols greatly impacts the level of microbial contamination.
Training and education for transport staff on proper handling practices can further enhance food safety during milk transport.

Influencing Factors on Microbial Contamination in Storage

Cow breed has minimal effect on microbial contamination levels in stored raw milk compared to factors like equipment cleanliness, cooling temperature, and hygiene practices.
