It's possible that Felicia did not properly clean her cooking surfaces or utensils, which may have allowed bacteria to contaminate her food.

Question 4

_____ is a type of parasitic worm that can be transferred to humans who eat raw or undercooked fish.

Accepted Answer

Anisakis is a type of parasitic worm commonly found in raw or undercooked fish.

Giardia and Cryptosporidium are parasites that are typically found in contaminated water or food. Salmonella is a type of bacteria that can be found in undercooked or contaminated meats as well as eggs, fruits, and vegetables. While salmonella can cause gastrointestinal symptoms similar to those caused by Anisakis, it is not exclusively associated with fish consumption.

Question 5

Which of the following types of pathogens is responsible for most cases of "traveler's diarrhea"?

However, the safest option for water is to drink only bottled or boiled water to avoid contracting any water-borne diseases.

Question 7

A ____ is simply a piece of genetic material coated with protein.

Accepted Answer

This is the definition of a virus. It is not a parasite because it cannot survive without a host cell, and it is not a bacterium or protozoan because those are complete organisms with their own genetic material.

Question 8

Which of the following statements is true?

Accepted Answer

Traveling to Central and South America exposes individuals to a higher risk of contracting traveler's diarrhea due to the prevalence of certain bacteria and viruses in the region. Microstrainer filters may not be effective in removing viruses, boiling water is an effective means of purification, and drinking water from swimming pools is not recommended as it may contain chlorine and other contaminants.

Question 9

Jordan is an American who is traveling through Indi A.Today,he's staying in home that's in a village about 50 miles southwest of New Delhi.To avoid traveler's diarrhea,Jordan should ________.

Accepted Answer

Using bottled water to drink, wash hands, brush teeth, and take medication is the best way to avoid traveler's diarrhea in India. Fresh water should not be trusted, and consuming raw foods from local street vendors can increase the risk of illness. It is also important to note that India is not considered a low-risk country for traveler's diarrhea.

Question 10

Which of the following practices is the most reliable way of sanitizing impure water?

Accepted Answer

Boiling water is the most reliable way of sanitizing impure water. Boiling the water for at least 1 minute (3 minutes at higher elevations) will kill any bacteria, viruses, and parasites that may be present in the water. Freezing and thawing, adding salt, or shaking the water vigorously will not remove harmful contaminants.

Question 11

The USDA recommends that fresh pork be cooked until its internal temperature is at least ________.

Accepted Answer

The USDA recommends that fresh pork be cooked until its internal temperature is at least 145ºF to ensure that any harmful bacteria present in the meat are destroyed. This temperature is lower than previously recommended to account for advancements in food safety and cooking methods. Cooking pork to an internal temperature of 155ºF can result in overcooked, dry meat.

Question 12

On her last camping trip,Jenny swallowed some water when she swam in a lake.Two days later,she suddenly experienced severe abdominal pain and watery diarrhe A.Based on this information,Jenny probably is infected with ________.

Accepted Answer

The symptoms of severe abdominal pain and watery diarrhea after swimming in a lake are consistent with an infection of Giardia, a parasite commonly found in contaminated water sources. Aflatoxin is a toxin produced by certain molds in food, Clostridium botulinum is associated with improperly canned food, and Bacillus cereus can cause gastrointestinal symptoms but is not typically associated with contaminated water sources.

Question 13

Franco made dinner for his roommates.The meal included a baked cut-up chicken,fruit salad,and stir-fried rice with mixed vegetables.About 8 hours after eating dinner,Franco and his roommates experienced nausea,vomiting,fever,chills,and diarrhe A.Based on this information,Franco probably ________.

The symptoms described are consistent with food poisoning, which can occur when bacteria from raw chicken are transferred to other foods. Not washing the knife after cutting the chicken and before cutting the fruit could easily spread bacteria, leading to the illness experienced.

Question 14

BJ wants to follow the "Check Your Steps" actions for food safety.When he prepares high-risk foods,he washes his hands before and after touching the food; sanitizes surfaces that come in contact with all foods; avoids cross contamination; cooks meats to their proper internal temperatures; and after meals,he keeps serving dishes with cooked food on the table,so his guests can nibble on the items.After eating one of his meals,he and his dinner guests developed a food-borne illness.Based on this information,which step did he fail to take?

Accepted Answer

BJ failed to chill the cooked food promptly after the meal. Keeping the serving dishes with cooked food on the table allows the food to remain at room temperature for an extended period, which can lead to the growth of harmful bacteria and cause foodborne illness.

Question 15

The USDA recommends that fresh turkey be cooked until its internal temperature is at least ________.

Accepted Answer

The USDA recommends that fresh turkey be cooked until its internal temperature is at least 165ºF to ensure that any harmful bacteria are killed. Cooking to this temperature also helps to prevent foodborne illness.
