Tell her boss. She should not contaminate a sterile tray.
Answer:
26dB
Explanation:
The decibel level β is a calculated by 10log (I/Io)
Where I and Io represent sound intensity
From the question, there's no interference. So
Where I = 4Io (because there are 4 men shouting), so the intensity will be 4 times larger.
β = 10log (I/Io)
β = 10log (4Io/Io)
β = 10log 4
β = 6.020599913279623
β = 6 ---- Approximated
The decibel level = 20 + 6.020599913279623
Decibel Level = 26.020599913279623
Decibel level =26dB --- Approximated
To prevent biological hazards from contaminating food, there are some steps that the food worker should follow:
- Wash hand properly before handling any food or after touching raw food to prevent the germs from spreading.
- Raw meat, poultry, and seafood should be kept in a sealed container to prevent cross-contamination.
- Cooking temperature. The minimum cooking temperature varies depending on the type of food. You can use the food thermometer to check the food temperature.
- Wash fruit and vegetables under cold running water before you eat them.
- Wash, clean and disinfectant the tools you use to avoid cross-contamination.
<h3>Further explanation
</h3>
Biological hazards or contamination happens when the food you eat contains some bacteria or harmful microorganisms. It is a common cause of food poisoning. Preparing, cooking and storing food correctly is important to minimize the risk of food poisoning. Most foods, especially meat, poultry, fish and eggs, should be cooked thoroughly to kill most types of food poisoning bacteria.
The cooking time and temperature depend on the type of food. It is to make sure the germs destroy but keep the nutrient. It is important to cook food to high enough temperatures so that any harmful germs that may be present in foods destroyed. In general, food should be cooked to a temperature of at least 75 °C or hotter.
