Paper Title
Microbial Load Of Pasteurized Cattle Milk At Different Packaging Materials And Storage Duration

Abstract
The study evaluated the mean microbial load of dairy milk at Cagayan State University Piat Cattle Project using three packaging materials; pet bottle, tetra pack, and glass bottle and at different storage durations: six(6), twelve (12) and twenty (24) hours. Samples were subjected to microbiological analysis for Aerobic Plate Count at the Department of Science and Technology (DOST), Tuguegarao., Cagayan. Results showed that pet packaging material produced the least mean microbial load on dairy and delayed the production and growth of microbes at different storage durations. Statistical analysis showed that the combined effect of the packaging material and storage duration on the mean microbial load of dairy milk is significant (P>0.01). This implies that with the use of pet packaging material for dairy milk can be stored for a longer period of time as compared to the glass and tetra pack packaging materials. Furthermore, Salmonella was absent in any of the three packaging materials used. This implies that any of the packaging materials can be used to store the dairy milk.
