What is the best way to avoid bacterial contamination quizlet?
timofeeve [1]

Before and after handling food, going to the bathroom, changing diapers, or touching pets, wash your hands with soap and hot water. To clean up spills or kitchen surfaces, use paper towels or clean cloths along with hot, soapy water. Use your washing machine's hot cycle to often wash cloths.

<h3>What is bacterial contamination?</h3>

When bacteria build up on food and make it spoil, this is called bacterial contamination. Eating that food can make you ill, either because of the toxins released by the bacteria or because of the germs themselves. According to bacteria contamination, there are three basic forms of foodborne sickness.

<h3>What is a typical bacterial contamination source?</h3>

The incidence, fate, movement, survival, and multiplication of pathogens in the multiple sites where they are found are all influenced by a number of factors, including contaminated manure, irrigation water, soil, cattle, and wildlife.

<h3>What is the most effective means of preventing biological contamination?</h3>
  • Food handlers must always adhere to safe food handling procedures to reduce the danger of biological food contamination and slow down bacterial growth.
  • Exclude high-risk foods from the temperature danger zone, such as meat, poultry, shellfish, eggs, and dairy.
  • High-risk foods should be properly bought, stored, thawed, prepared, cooked, and served.
