In which ways can foodborne illnesses be prevented? Select all that apply.
Refrigerate foods promptly at 40 degrees Fahrenheit or below
Use different cutting boards for produce, meat, bread, poultry, and fish
Washing hands and kitchen surfaces often
Use hot sauce to kill microbes that might be in raw foods
Thaw raw meat in the kitchen sink in a basin of water
Correct Answer : A,B,C
A. Refrigerating foods promptly at 40°F (4°C) or below slows the growth of bacteria such as Salmonella, E. coli, and Listeria, which are common causes of foodborne illness. Leaving perishable foods at room temperature allows bacteria to multiply rapidly, increasing the risk of infection. Foods should be stored in the refrigerator within two hours of preparation, or within one hour if the ambient temperature is above 90°F (32°C).
B. Using different cutting boards for produce, meat, bread, poultry, and fish prevents cross-contamination. Bacteria from raw foods can transfer to ready-to-eat foods like fruits, vegetables, or bread if the same cutting board or utensils are used. Separate cutting boards and utensils minimize this risk, and color-coded boards can help maintain separation in both home and professional kitchens.
C. Washing hands and kitchen surfaces often is essential to prevent the spread of pathogens. Hands should be washed with soap and warm water for at least twenty seconds before handling food, after touching raw meat, using the restroom, or handling garbage. Kitchen surfaces, utensils, and equipment should also be cleaned and sanitized regularly to remove bacteria and prevent contamination.
D. Using hot sauce does not reliably kill harmful microbes in raw foods. While some acids or spices may have minimal antimicrobial effects, they are not sufficient to make raw or improperly handled food safe.
E. Thawing raw meat in the kitchen sink or in a basin of water at room temperature is unsafe because the outer layers of the food can reach temperatures that promote rapid bacterial growth while the inside remains frozen. Safe thawing methods include thawing in the refrigerator, submerging in cold water in a sealed bag while changing the water every thirty minutes, or using a microwave to thaw, followed by immediate cooking.

Correct Answer is D
Explanation
A. Disaccharides are carbohydrates composed of two sugar molecules linked together, such as sucrose (table sugar), lactose, and maltose. They are simpler than polysaccharides and provide quick energy but are not considered complex carbohydrates.
B. Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar molecule such as glucose, fructose, or galactose. They are the building blocks of more complex carbohydrates but are not complex carbohydrates themselves.
C. Glycogen is a specific type of polysaccharide that serves as the body’s storage form of glucose in liver and muscle tissues. While glycogen is a complex carbohydrate, the term in the question refers to complex carbohydrates in general, not just the stored form.
D. Polysaccharides are complex carbohydrates composed of long chains of glucose units linked together. Examples include starch (found in plants), glycogen (stored in animals), and cellulose (a structural component in plants). Polysaccharides provide sustained energy as they are broken down more slowly than simple sugars and play roles in energy storage and structural support.
Correct Answer is D
Explanation
A. Vitamin E is present in breast milk at levels generally sufficient for healthy, full-term infants. It functions as an antioxidant, protecting cell membranes from oxidative damage. Deficiency is very rare in breastfed infants unless there is a fat malabsorption disorder or premature birth with very low birth weight, as these conditions limit fat-soluble vitamin absorption. Therefore, routine supplementation is not required for most term infants.
B. Vitamin C is water-soluble and abundant in breast milk when the lactating mother has an adequate diet. It supports collagen formation, immune function, and antioxidant activity. Deficiency in breastfed infants is uncommon unless the mother’s intake is severely inadequate, which is rare in most populations.
C. Calcium is a critical mineral for bone and teeth development, and breast milk generally contains sufficient calcium to meet the needs of full-term infants. The infant’s calcium requirements are met even if maternal intake is moderate because the mammary gland actively regulates calcium content in milk. Deficiency in calcium is therefore not a common concern in healthy, exclusively breastfed infants.
D. Vitamin D is naturally present in breast milk in very low amounts, insufficient to meet the infant’s needs, particularly if sunlight exposure is limited. Vitamin D is essential for calcium absorption and bone mineralization. Without supplementation, breastfed infants are at risk for rickets, delayed bone growth, and skeletal deformities. Health organizations, such as the American Academy of Pediatrics, recommend daily vitamin D supplementation (typically 400 IU/day) for all exclusively breastfed infants.
