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 B
Explanation
A. Micronutrients are nutrients that the body needs in small amounts, such as vitamins and trace minerals. While essential for health, they are required in much smaller quantities than macronutrients.
B. Macronutrients are nutrients that the body requires in relatively large amounts to provide energy and support growth, development, and overall physiological function. The main macronutrients include carbohydrates, proteins, fats (lipids), and water. These nutrients provide calories (except water) and are critical for cellular structure, energy metabolism, and maintaining homeostasis.
C. Organic molecules refer to chemical compounds that contain carbon and hydrogen, such as carbohydrates, proteins, fats, and vitamins. While some macronutrients are organic, the term does not specifically indicate the nutrient requirement in large amounts.
D. Inorganic molecules, such as minerals and water, do not contain carbon-hydrogen bonds. Some are macronutrients (like water) or micronutrients (like iron), but the term is too broad to specifically define nutrients needed in large amounts.
Correct Answer is C
Explanation
A. A chronic autoimmune disorder affecting the respiratory lining, such as asthma or chronic bronchitis, is not the same as anaphylaxis. These conditions involve long-term inflammation but are not acute, systemic allergic reactions.
B. A mild, localized allergic response, such as hives or itching (pruritus), involves limited areas of the body and does not threaten life. Anaphylaxis, in contrast, is systemic and life-threatening.
C. Anaphylaxis is a severe, systemic allergic reaction that can rapidly affect multiple organ systems. It often includes symptoms such as airway swelling, bronchoconstriction, hypotension, rapid pulse, dizziness, and even cardiovascular shock. Without prompt treatment, typically with intramuscular epinephrine, anaphylaxis can be fatal. The reaction is usually triggered by allergens such as foods, insect stings, medications, or latex.
D. Non-allergic food intolerances, such as lactose intolerance, can cause gastrointestinal discomfort like bloating, cramping, or diarrhea, but they do not involve systemic immune activation, airway obstruction, or cardiovascular collapse.
