What temperature must water reach to effectively sanitize using heat?

To effectively sanitize using heat, the water must reach a temperature of 77 degrees Celsius. At this temperature, most harmful microorganisms, including bacteria, viruses, and parasites, are killed or inactivated in a short period. The heat denatures proteins in these pathogens, disrupting their cellular functions and leading to their destruction.

Sanitizing is an essential step in food safety practices, as it helps to reduce the risk of foodborne illnesses. This temperature threshold is supported by safety guidelines and regulations that ensure that surfaces, utensils, and food contact items are adequately disinfected.

Lower temperatures, such as 50 degrees Celsius, 60 degrees Celsius, and 70 degrees Celsius, may not be sufficient to achieve effective sanitization, as they may not reliably eliminate all pathogens in the time required or may only reduce microbial load rather than completely sanitize. This is particularly crucial in a food safety context, where maintaining high standards for cleanliness can prevent outbreaks of foodborne diseases.
