1.0 KEY TERMS Foodborne illness: Illness carried or transmitted to people by food. Contamination: Presence of harmful substances in food. Some food safety hazards occur naturally, while others are introduced by humans or the environment. Foodborne illness outbreak: An incident in which two or more people experience the same illness symptoms after eating the same food. An investigation is conducted by the state and local regulatory authorities, and the outbreak is confirmed by a laboratory analysis.
1.0 KEY TERMS Time-temperature abuse: Food has been time- temperature abused any time it has been allowed to remain too long at a temperature favorable to the growth of foodborne microorganisms. Cross-contamination occurs when microorganisms are transferred from one food or surface to another. TCS food: Food that contains moisture and protein and has a neutral or slightly acidic pH. Such food requires time- temperature control to prevent the growth of microorganisms and the production of toxins.
1.0 KEY TERMS Ready-to-eat food: Any food that is edible without further preparation, washing, or cooking. It includes washed fruit and vegetables, both whole and cut; deli meats; and bakery items. Sugars, spices, seasonings, and correctly cooked food items are also considered ready-to-eat. High-risk populations: People susceptible to foodborne illness due to the effects of age or health on their immune systems, including infants and preschool-age children, pregnant women, older people, people taking certain medications, and those with certain diseases or weakened immune systems. Immune system: The body s defense\system against illness. People with compromised immune systems are more susceptible to foodborne illness.
1.1 Identify Foodborne Illness and Recognize when it has occurred Foodborne Food What is Foodborne Illness? Illness Illness 7
Identify Foodborne Illness and Recognize when it has occurred 1.1 How is foodborne illness identified? Two or more people believe they got ill from the same source Investigation completed by a regulatory authority, e.g. FDA, USDA, County Health Dept., etc. Analysis of regulatory findings by a laboratory Laboratory releases report that either supports or contradicts the original findings Final Report Released and Possible Foodborne Illness Confirmed or Ruled Out Findings and Samples Sent to Lab and Analyzed Two People Get Ill From the Same Source Regulatory Authority Investigates 8
