Answer

B

Explanation

Temperature abuse refers to the improper storage or handling of food at temperatures that allow bacteria to grow, potentially leading to foodborne illnesses. In this question, we are asked to identify which of the given options represents temperature abuse.1. Thawing foods in running water below 70 degrees F: This is not temperature abuse. It is a safe method for thawing foods as it keeps the food out of the temperature danger zone (between 40°F and 140°F) where bacteria can grow rapidly.2. Holding chill at 145 degrees F: This is temperature abuse. Foods should be held at temperatures below 140°F to prevent bacterial growth. Holding food at 145°F puts it in the temperature danger zone, allowing bacteria to grow and potentially causing foodborne illnesses.3. Storing raw chicken breasts at 42 degrees F: This is not temperature abuse. It is a safe storage temperature for raw chicken, which should be stored at temperatures above 40°F to prevent bacterial growth.4. Cooking ground beef to an internal temperature of 155 degrees F: This is not temperature abuse. Ground beef should be cooked to an internal temperature of 160°F to ensure that harmful bacteria are killed. Cooking to 155°F may not kill all harmful bacteria, but it is not considered temperature abuse as it is still a safe cooking temperature.Therefore, the correct answer is option B, holding chill at 145 degrees F, as it represents temperature abuse by placing food in the temperature danger zone, allowing bacteria to grow and potentially causing foodborne illnesses.
