Question 5

According to the Food Additives Amendment of 1958,

Accepted Answer

The Food Additives Amendment of 1958 placed additives that were in use and deemed safe prior to 1958 on the GRAS (Generally Recognized as Safe) list, meaning that they did not need to be tested for safety. However, new additives still needed to be tested for safety before being approved for use in food. The Delaney Clause, which prohibited the approval of any additive that caused cancer in humans or animals, was not part of the Amendment but was a separate provision in the same law.

Question 6

Which of the following safety steps should you take if your home experiences a loss of electricity that lasts for several days?

Accepted Answer

Cooking foods and boiling water on a charcoal grill that is outdoors is the safest option as it prevents any risk of carbon monoxide poisoning from using gas stoves or ovens. It also avoids the risk of fire within the house. Additionally, using water from a swimming pool or car's radiator is not recommended as it may contain harmful chemicals or bacteria. Raw or cooked foods from the refrigerator may spoil quickly without electricity. Serving food from dented or bulging cans may also be a health risk.

Question 8

The following substances were detected in a slice of enriched bread.Which of the substances is a not a direct food additive?

Accepted Answer

Plastic wrap is not a direct food additive, but a packaging material that may come into contact with the food during storage or transportation. Thiamin, sugar, and folic acid are all direct food additives that are intentionally added to the bread to enhance its nutritional value, texture, and taste.

Question 9

You have a high risk of developing traveler's diarrhea when you visit

Accepted Answer

Calcutta is known to have a higher risk of traveler's diarrhea due to poor sanitation and hygiene practices. It is important to take precautions such as avoiding tap water, ice, and uncooked foods.

D) New York City, New York
 Although there is a lower risk of traveler's diarrhea in developed countries like the United States, New York City can be an exception due to its large population and diverse food options. It is important to practice good hygiene and food safety practices to reduce the risk of illness.

Question 10

During a natural disaster,it is safe to drink the water from

Accepted Answer

Melted ice cubes in the freezer are the safest option as they are likely to have been made from clean water. It is important to avoid drinking water from swimming pools, car or truck radiators, and toilet bowls as they may contain harmful chemicals or bacteria.

Question 11

Accepted Answer

During a power outage, it is important to not eat raw or cooked foods that have been at room temperature for more than 2 hours. Bacteria can grow rapidly at room temperature and can cause food-borne illness. Using a charcoal grill in the kitchen is dangerous and can cause carbon monoxide poisoning. Using water from a swimming pool or car's radiator is not safe for consumption or washing dishes. Serving foods from dented or bulging cans first is not safe as they may be contaminated or spoiled.

Question 12

You have a high risk of developing traveler's diarrhea when you visit

Accepted Answer

Mexico City, Mexico is known for having a higher risk of traveler's diarrhea due to the food and water quality. Travelers should take precautions such as drinking bottled water, avoiding ice and raw foods, and practicing good hygiene. Tokyo, Japan and Montreal, Canada have a lower risk of traveler's diarrhea and Los Angeles, California is generally considered low risk.

Question 13

Which of the following food preservation methods draws water from cells,reducing the likelihood many pathogens can survive?

Accepted Answer

Drying draws water from cells, which reduces the likelihood of many pathogens being able to survive. This is because many pathogens need water to survive and reproduce. Canning uses heat to kill pathogens, chilling slows down their growth, and irradiating damages the DNA of pathogens to prevent reproduction.

Question 14

How can you tell if a food has been irradiated to preserve it?

Accepted Answer

The Radura symbol is a universal symbol used to indicate that food has been irradiated, making it the most reliable way to tell if a food has been irradiated. The other options do not necessarily indicate if a food has been irradiated.

Question 15

During a natural disaster,it is safe to drink the fluid from

Accepted Answer

The general guideline for emergency water supply is 1 gallon per person per day. James and his five relatives make a total of 6 people. Multiplying 1 gallon by 6 people and then further multiplying it by 5 days gives us a total of 30 gallons of water. Therefore, James should store at least 30 gallons of clean water.

Question 18

The _____ prohibits food manufacturers from adding a new compound to food that causes cancer.

Accepted Answer

The Delaney Clause, which is a part of the Food Additives Amendment to the federal Food, Drug, and Cosmetic Act, prohibits the addition of any substance to food that has been shown to cause cancer in humans or animals. This clause is an important safeguard against the use of harmful chemicals in food products. The other options are not relevant to this specific regulation.

Question 19

The following substances were detected in a can of food.Which of the substances is a direct food additive?

Accepted Answer

High-fructose corn syrup is a direct food additive, which means it is intentionally added to food during processing. Mouse hairs, pesticide residues, and insect eggs are all contaminants that can be found in food but are not intentionally added as ingredients.

Question 20

Which of the following food preservation methods treats the food with a high amount of energy that destroys the genetic material of pathogens?

Accepted Answer

Irradiating is the food preservation method that treats the food with a high amount of energy in the form of ionizing radiation. This radiation destroys the genetic material of pathogens and prevents their growth and reproduction, thereby increasing the shelf life of the food. Drying, chilling, and canning do not involve the use of ionizing radiation.
