Proper Handwashing Techniques in Food Safety: A Comprehensive Guide
Hand hygiene is a critical component of food safety, as it plays a significant role in preventing the spread of foodborne illnesses. According to the Centers for Disease Control and Prevention (CDC), proper handwashing can reduce the risk of foodborne illness by 50. In this article, we will delve into the importance of handwashing, discuss the steps involved in proper hand hygiene, and provide detailed information on the techniques used to ensure clean hands.
The Importance of Hand Hygiene
Hand hygiene is essential in preventing the spread of microorganisms that can cause foodborne illnesses. These illnesses are caused by bacteria, viruses, and parasites that can be transmitted through contaminated foods or surfaces. When an individual handles food without proper handwashing, they risk transferring these pathogens to the food, ultimately leading to illness.
In the food industry, hand hygiene is a critical component of food safety protocols. Food handlers must adhere to strict guidelines for hand washing, including the use of soap and water, drying hands thoroughly, and avoiding certain practices that can compromise hand hygiene (such as wearing artificial nails or using nail polish).

1. Wet your hands under running water
