1. 1. Bệnh do Thực phẩm

   A line cook at a taquería leaves a pan of cooked carnitas on the counter at room temperature during a slow afternoon. Which range describes the Temperature Danger Zone where bacteria grow most rapidly?

   • a.50°F to 150°F
   • b.70°F to 125°F
   • c.32°F to 100°F
   • d.41°F to 135°F

   Đáp án: d

   Giải thích: The Temperature Danger Zone is 41°F to 135°F; bacteria multiply fastest between these limits, and growth is most rapid from 70°F to 125°F. Cold holding must stay at or below 41°F and hot holding at or above 135°F to keep food out of the zone. The other ranges are incorrect because they do not match the Food Code limits.

2. 2. Bệnh do Thực phẩm

   An intoxication (like Staphylococcus aureus food poisoning) differs from an infection because:

   • a.It requires the bacteria to keep multiplying in the body
   • b.It cannot be prevented by good hygiene
   • c.It is only caused by viruses
   • d.The illness is caused by a toxin already present in the food, so symptoms come on quickly

   Đáp án: d

   Giải thích: In an intoxication, the person eats a toxin already produced in the food (for example by Staphylococcus aureus, often introduced by bare-hand contact), so symptoms appear quickly, sometimes within hours. An infection requires living pathogens to multiply in the body, with a slower onset. Good hygiene, especially handwashing and no bare-hand contact, helps prevent Staph intoxication.

3. 3. Ô nhiễm & Chất gây dị ứng

   The FDA Food Code requires that most ready-to-eat foods be handled without bare-hand contact. This mainly reduces the risk of:

   • a.Physical contamination from glass
   • b.Chemical contamination from sanitizer
   • c.Allergen cross-contact only
   • d.Biological contamination from pathogens on hands

   Đáp án: d

   Giải thích: Handling ready-to-eat food with gloves, tongs, or other utensils instead of bare hands reduces biological contamination from pathogens like Norovirus, Hepatitis A, Shigella, and Staph carried on hands. While good practices also help with allergens, the bare-hand rule primarily targets pathogen transfer. It is not aimed at glass or sanitizer.

4. 4. Vệ sinh Cá nhân

   Why must food handlers wear an effective hair restraint such as a hat or hairnet?

   • a.Because uniforms look more professional
   • b.To keep hair from falling into food and to reduce the temptation to touch the hair with the hands
   • c.To keep the handler's head warm
   • d.Only because customers dislike seeing hair

   Đáp án: b

   Giải thích: Hair restraints such as caps, hairnets, and beard covers keep hair out of food and discourage handlers from touching their hair, which can transfer oils and pathogens to the hands. The purpose is food safety, not just appearance or comfort. Loose hair is a physical contaminant and a route for Staphylococcus that lives on skin and hair.

5. 5. Nhận hàng & Bảo quản

   A receiving clerk notices that several cans in a delivery have deep dents on the side seams, and one can is swollen. What should the clerk do?

   • a.Accept them and use the swollen can first
   • b.Wipe the cans and store them normally
   • c.Accept them if the labels are intact
   • d.Reject the swollen and seam-dented cans, since these defects can indicate contamination such as botulism

   Đáp án: d

   Giải thích: Cans that are swollen, leaking, rusted, or dented on a seam must be rejected, because these defects can allow contamination or indicate Clostridium botulinum growth. A swollen can is a serious warning sign of gas from toxin-forming bacteria. Intact labels do not make a damaged can safe, and a swollen can must never be used or opened for tasting.

6. 6. Sơ chế & Nấu nướng

   A new prep cook asks the kitchen manager to list every approved way to thaw a case of frozen chicken breasts. Which answer is correct?

   • a.In a cooler at 41°F or lower, under running potable water at 70°F or lower, in a microwave if cooked immediately, or as part of the cooking process
   • b.In a cooler, under running water, in warm standing water, or as part of the cooking process
   • c.Only in a cooler at 41°F or lower, because all other methods let the food enter the danger zone
   • d.In a cooler, on a prep counter at room temperature, under running water, or in a microwave

   Đáp án: a

   Giải thích: The FDA Food Code allows exactly four thawing methods: refrigeration at 41°F or lower, submerged under running drinkable water at 70°F or lower, in a microwave when cooking continues immediately, and as part of the cooking process. Room-temperature counters and standing warm water are never approved because the outer layers of the food would sit in the temperature danger zone.

7. 7. Sơ chế & Nấu nướng

   A cook places cold leftover gravy directly into the steam table well at opening and lets it slowly climb to temperature over 3 hours. What did the cook do wrong?

   • a.The gravy should have gone into the well frozen so it heats evenly
   • b.Hot-holding equipment must not be used to reheat food; the gravy needed to reach 165°F within 2 hours using cooking equipment first
   • c.The gravy should have been reheated to 145°F before going into the well
   • d.Nothing; the steam table will eventually bring the gravy to 165°F

   Đáp án: b

   Giải thích: Steam tables and other hot-holding units are designed to maintain temperature, not raise it quickly. Reheating in them leaves food in the danger zone too long. Leftover gravy must be reheated to 165°F within 2 hours on a stove, oven, or other cooking equipment before being transferred to hot holding.

8. 8. Giữ nóng/lạnh & Phục vụ

   A catering crew arrives at an event and probes the shrimp cocktail from the cold carrier at 44°F. The crew chief knows the shrimp left the commissary at 38°F one hour ago. What is the best course of action?

   • a.Get it onto ice or into refrigeration to bring it back to 41°F or below, since the time above 41°F was brief and known
   • b.Reheat the shrimp to 165°F and serve it hot
   • c.Serve it immediately since seafood is resilient
   • d.Discard the shrimp because it exceeded 41°F

   Đáp án: a

   Giải thích: Cold food found above 41°F for a short, documented time can be cooled back down as a corrective action; the risk grows with time in the danger zone, which here was limited and known. If the time were unknown or extended, discarding would be required.

9. 9. Quản lý & HACCP

   A grocery deli wants to grow sprouts from seeds in-house for its salads. Regarding the Food Code, what does this activity trigger?

   • a.Only a produce-washing log
   • b.No special requirement, because sprouts are just vegetables
   • c.A variance requirement, because sprouting seeds is a specialized process with elevated pathogen risk
   • d.A ban on all leafy greens

   Đáp án: c

   Giải thích: Sprouting seeds or beans is one of the specialized processes the Food Code lists as requiring a variance because the warm, moist growing conditions readily support pathogen growth, and sprouts have caused multiple outbreaks. The operation must obtain the variance and typically maintain a HACCP plan. Simply washing produce does not address this specific hazard.

10. 10. Cơ sở, Vệ sinh & Côn trùng

    Which set of practices forms the foundation of Integrated Pest Management (IPM)?

    • a.Spraying pesticide daily throughout the kitchen
    • b.Leaving food out to lure pests to one spot
    • c.Deny pests access, deny them food and water, and deny them shelter, using a licensed operator when treatment is needed
    • d.Propping the back door open for ventilation

    Đáp án: c

    Giải thích: IPM rests on denying pests entry, food and water, and shelter, so the environment simply does not support them; chemical treatment is a last resort performed by a licensed pest control operator. Routine daily spraying, luring pests with food, or propping doors open all work against these principles. Prevention through exclusion and sanitation is far more effective than reacting with pesticides.
