Food Safety
Both heat and acidity are necessary to ensure a safe
product. Always pasteurize raw milk or use commercially
pasteurized milk to make yogurt.
Discard any yogurt samples with visible signs of
microbial growth or any odors other than the acidic
smell of fresh yogurt. Discard batches that fail to set
properly since this may be an indication of a bad
culture or unwanted microorganisms.
Always use clean and sanitized equipment and containers
to ensure a long shelf life for your yogurt.
Clean equipment and containers in hot detergent
water, then rinse well and air dry.
Ingredients added to yogurt should be clean and of
good quality so they do not add undesirable microorganisms
to the yogurt.
