    Abstract

    The aim of research to determine safety level and the growth of Staphylococcus aureus and Escherichia coli in pasteurized milk in Surabaya region during storage at refrigerator temperature. Sample from ten milk pasteurized product in region Surabaya with conducting simple pasteurisasi process Sampel taked about in the morning (06.00 a.m.) and which. after storage during one day, two-day, three-day and four day at temperature refrigerator. Parameters which observed are total bacteria, Staphylococcus aureus and Escherichia coli growth, degree of acidity, alcohol test, reduktase number, colour changes, odor and apperance of milk. Result of research indicated that total bacteria , Staphylococcus aureus and Escherichia coli growth when one day storage is zero (0 CFUlml) of all pasteurized milk and safety to be consumed. At one day during storage, 70% of pasteurized milk have not safety to consumed. At during two-day storage, 100% of pasteurized milk have not safety to consumed with total bacteria, total Staphylococcus aureus and Escherichia coli more than SNI standard. During storage at refrigerator temperature, what happened by the improvement of total bacteria, total Staphylococcus aureus and Escherichia coli. but do not showed of change at colour, aroma and appearence. Result of alcohol test showed negativity Keyword: Pasteurized Milk, safety level, storage, refrigerator temperature
