Answer :
Final answer:
The most likely source of food contamination among the options given is a sick employee who sneezes on food. This scenario can directly introduce pathogens into food, posing health risks. Additionally, failing to wash hands when changing gloves also increases contamination risks.
Explanation:
Identifying Sources of Food Contamination
In the context of food safety, food contamination can occur from various sources. Among the options provided:
- A sick employee who sneezes on food
- Cooking chicken to the correct internal temperature of 155°F
- Failing to wash hands when changing gloves
The first option, a sick employee who sneezes on food, is definitely a likely source of food contamination. When an employee is sick, especially with a respiratory illness, they can transmit pathogens (such as bacteria or viruses) through droplets that settle on food, leading to potential foodborne illnesses.
The second option, cooking chicken to the correct internal temperature of 155°F, is a safe practice that helps eliminate pathogens, thereby reducing the risk of food contamination. Therefore, this option does not represent a source of contamination.
The third option, failing to wash hands when changing gloves, also poses a risk of contamination. If an employee does not properly wash their hands, bacteria from their hands can transfer to the food or food surfaces, increasing the likelihood of contamination.
In summary, the first option is the most direct source of food contamination, followed by the third, as both relate to improper handling of food.
