Bacteria grows and multiplies rapidly unless kept in check by good sanitation, food safety, and personal hygiene. Many procedures are routinely used in food safety that include cooking, chilling, cleaning, and avoiding cross-contamination. In this experiment, milk will be used as a growth medium for bacteria. A blue dye will be added that turns colorless when bacteria grow in it. The impact of cooking, chilling, and cross-contamination will be tested to determine bacterial growth.
