Trichinosis is a foodborne illness that is cause by
- A.
Undercooked pork
- B.
Moldy cheese
- C.
Past-dated milk
- D.
Unsanitized work surfaces
Correct Answer
A. Undercooked porkExplanation
Trichinosis is a foodborne illness caused by consuming undercooked pork. This is because the pork may contain Trichinella spiralis, a parasitic worm that can infect humans. When pork is not cooked at a high enough temperature, the worms are not killed and can cause infection when ingested. Therefore, undercooked pork is the most likely cause of trichinosis.Rate this question:

Which one of the following conditions is necessary for viruses to survive and reproduce?
- A.
They need a living cell to reproduce
- B.
Grow only in food at certain acidity levels
- C.
Grow in high-protein food
- D.
Grow only at temperatures between 41F (5C) and 135F (57)
Correct Answer
A. They need a living cell to reproduceExplanation
Viruses are obligate intracellular parasites, meaning they require a living cell to reproduce. Unlike other organisms, viruses lack the necessary cellular machinery to carry out essential life processes on their own. Instead, they invade host cells and hijack their cellular machinery to replicate and produce more viruses. This dependence on a living cell is crucial for the survival and reproduction of viruses. Without a host cell, viruses cannot replicate and therefore cannot survive.Rate this question:

- A.
Calorie-Rich food
- B.
Moist food
- C.
Hot food
- D.
Frozen food
Correct Answer
B. Moist foodExplanation
Bacteria are most likely to grow in moist food because moisture provides an ideal environment for their growth and reproduction. Bacteria require water to survive and multiply, and moist food provides the necessary moisture content. In contrast, calorie-rich food, hot food, and frozen food are not as conducive to bacterial growth. Calorie-rich food may provide energy for bacteria, but without moisture, their growth is limited. Hot food and frozen food can inhibit bacterial growth due to high temperatures and low temperatures respectively. However, moist food provides the perfect conditions for bacteria to thrive.Rate this question:
