  1. To prevent foodborne illness and ensure the safety of consumers

  2. To enhance the taste and appearance of food

  3. To reduce the cost of food production

  4. To increase the shelf life of food


Correct Option: A
Explanation:

The primary objective of food safety practices is to prevent foodborne illness and ensure the safety of consumers by controlling and eliminating hazards that can cause foodborne diseases.

What is food irradiation?

  1. A process that involves exposing food to high doses of radiation to kill bacteria and other microorganisms

  2. A method of food preservation that involves freezing food at very low temperatures

  3. A technique used to enhance the flavor and texture of food

  4. A process that involves adding preservatives to food to prevent spoilage


Correct Option: A
Explanation:

Food irradiation is a process that involves exposing food to high doses of radiation, typically gamma rays or electron beams, to kill bacteria, viruses, parasites, and other microorganisms that can cause foodborne illness.

What is the primary purpose of food irradiation?

  1. To improve the nutritional value of food

  2. To enhance the taste and appearance of food

  3. To reduce the risk of foodborne illness by eliminating harmful microorganisms

  4. To increase the shelf life of food by slowing down spoilage


Correct Option: C
Explanation:

The primary purpose of food irradiation is to reduce the risk of foodborne illness by eliminating harmful microorganisms such as bacteria, viruses, and parasites that can cause foodborne diseases.

Which of the following foodborne pathogens can be effectively controlled by food irradiation?

  1. Salmonella

  2. E. coli

  3. Listeria monocytogenes

  4. All of the above


Correct Option: D
Explanation:

Food irradiation is effective in controlling a wide range of foodborne pathogens, including Salmonella, E. coli, and Listeria monocytogenes, which are responsible for some of the most common foodborne illnesses.

What is the maximum radiation dose allowed for food irradiation in the United States?

  1. 1 kGy

  2. 10 kGy

  3. 100 kGy

  4. 1 MGy


Correct Option: A
Explanation:

The maximum radiation dose allowed for food irradiation in the United States is 1 kGy (kiloGray), which is equivalent to 1000 Gray (Gy).

Which of the following foods is commonly irradiated in the United States?

  1. Chicken

  2. Beef

  3. Pork

  4. All of the above


Correct Option: D
Explanation:

In the United States, chicken, beef, and pork are among the most commonly irradiated foods.

What is the primary benefit of irradiating spices and herbs?

  1. To improve their flavor and aroma

  2. To reduce their moisture content

  3. To eliminate harmful microorganisms

  4. To enhance their nutritional value


Correct Option: C
Explanation:

Irradiating spices and herbs is primarily done to eliminate harmful microorganisms, such as Salmonella and E. coli, which can cause foodborne illness.

What is the main advantage of food irradiation over other food preservation methods?

  1. It does not alter the nutritional value of food

  2. It does not require the use of chemicals

  3. It is more cost-effective than other methods

  4. All of the above


Correct Option: D
Explanation:

Food irradiation offers several advantages over other food preservation methods, including the fact that it does not alter the nutritional value of food, does not require the use of chemicals, and is generally more cost-effective.

Which international organization is responsible for setting standards and guidelines for food irradiation?

  1. World Health Organization (WHO)

  2. Food and Agriculture Organization (FAO)

  3. International Atomic Energy Agency (IAEA)

  4. All of the above


Correct Option: D
Explanation:

The World Health Organization (WHO), Food and Agriculture Organization (FAO), and International Atomic Energy Agency (IAEA) all play a role in setting standards and guidelines for food irradiation.

What is the recommended storage temperature for irradiated food?

  1. Room temperature

  2. Refrigerated (4°C or below)

  3. Frozen (-18°C or below)

  4. Any of the above


Correct Option: B
Explanation:

Irradiated food should be stored refrigerated (4°C or below) to maintain its quality and safety.

Is food irradiation a widely accepted food preservation method globally?

  1. Yes, it is accepted in most countries

  2. No, it is banned in many countries

  3. It varies from country to country

  4. It is only accepted in developing countries


Correct Option: C
Explanation:

The acceptance of food irradiation varies from country to country. While it is widely accepted in some countries, it is banned or restricted in others.

What is the primary concern regarding the safety of irradiated food?

  1. The formation of harmful compounds during irradiation

  2. The loss of nutritional value due to irradiation

  3. The potential for increased microbial growth after irradiation

  4. The development of antibiotic resistance in bacteria due to irradiation


Correct Option: A
Explanation:

The primary concern regarding the safety of irradiated food is the potential formation of harmful compounds, such as free radicals, during the irradiation process.

What is the recommended maximum absorbed dose for irradiating fruits and vegetables?

  1. 1 kGy

  2. 10 kGy

  3. 100 kGy

  4. 1 MGy


Correct Option: A
Explanation:

The recommended maximum absorbed dose for irradiating fruits and vegetables is 1 kGy (kiloGray), which is equivalent to 1000 Gray (Gy).

Which of the following is NOT a benefit of food irradiation?

  1. It extends the shelf life of food

  2. It improves the nutritional value of food

  3. It reduces the risk of foodborne illness

  4. It controls insect infestation in food


Correct Option: B
Explanation:

Food irradiation does not improve the nutritional value of food. In fact, it may slightly reduce the levels of some nutrients, such as vitamin C and thiamine.

What is the primary role of regulatory agencies in ensuring the safety of irradiated food?
