Final answer:
All dairy products must be made from pasteurized milk because pasteurization eliminates harmful microorganisms, ensuring the safety of the dairy products for consumption.
Step-by-step explanation:
All dairy products must be made from pasteurized milk. This question is primarily related to health safety standards and the processing of milk for human consumption. Pasteurization is crucial as it eliminates deadly microorganisms that can be present in raw milk. Raw dairy products, including raw milk and cheeses made from it, are known to carry a risk of foodborne illnesses.
Therefore, regulations often require that milk be pasteurized to ensure its safety before being processed into dairy products. Even though dairy products can be made from full-fat, skimmed, or powder milk, they should all be pasteurized to be safe for consumption. UHT pasteurization is another process where milk is heated at 138 °C for 2 or more seconds, maintaining its safety for an extended shelf life without refrigeration.
