Capitolo 26, Problema 7
________ and ________are the two types of food poisoning.
Guida verificata passo dopo passo1
Understand that food poisoning can be classified based on the cause and mechanism by which the illness occurs.
Identify the first type: Food poisoning caused by ingestion of preformed toxins produced by bacteria in the food, known as 'intoxication'.
Identify the second type: Food poisoning caused by ingestion of food contaminated with pathogenic bacteria that then grow and produce toxins inside the host, known as 'infection'.
Recognize that these two types are commonly referred to as 'food intoxication' and 'food infection'.
Summarize that the two types of food poisoning are 'food intoxication' and 'food infection'.
