CPFM Practice Test 1 — Questions and Answers

Question 1: If your water system is found to be contaminated with E. coli, you must do:

For 30 days, only drink bottled water.
B). Post a required written boil water notice at the establishment. (Correct answer)
No water is served in the establishment.
Discontinue operations and close the establishment until the water system has been thoroughly cleaned and flushed.

Correct answer: B). Post a required written boil water notice at the establishment.

If a water system is contaminated with E. coli, it poses a severe health risk. Posting a required written boil water notice is a crucial immediate action to inform customers and staff that water must be boiled before use to kill harmful bacteria, thereby preventing waterborne illnesses. This is a standard public health protocol.

Question 2: What materials are suitable for floor coverings in food preparation areas?

Any type of flooring can be used if it has been sealed.
Textured natural fibers such as jute or hemp
Tile or other impervious materials with smooth, easily cleanable surfaces (Correct answer)
Spill-absorbent woven carpet

Correct answer: Tile or other impervious materials with smooth, easily cleanable surfaces

In food preparation areas, floor coverings must be durable, non-absorbent, and easy to clean to maintain hygiene and prevent the growth of bacteria. Tile or other impervious materials with smooth, easily cleanable surfaces meet these requirements, allowing for effective sanitation and preventing the accumulation of food debris and moisture.

Question 3: Which control measure should be implemented if your HACCP team has identified a biological hazard in the chicken at your food establishment?

Include an appropriate cooking system in the kitchen facilities for all cooking, cooling, and hot-holding of chicken. (Correct answer)
Use only locally sourced chicken until the biological hazard is resolved.
Soak all chicken used as a food ingredient in a bleach-water solution for 10 minutes to sterilize it.
Change the way chickens are used in the establishment by revisiting and updating the HACCP plan.

Correct answer: Include an appropriate cooking system in the kitchen facilities for all cooking, cooling, and hot-holding of chicken.

A biological hazard in chicken, such as bacteria, is effectively controlled by ensuring the product reaches a safe internal cooking temperature. Implementing an appropriate cooking system that guarantees proper cooking, cooling, and hot-holding temperatures is a critical control point in a HACCP plan to eliminate or reduce these hazards to an acceptable level.

Question 4: Which of the following is a responsibility of food managers?

Preventing pathogen growth and spread by keeping the facilities clean on a regular basis (Correct answer)
Addressing structural issues in the kitchen when they arise
Pre-operational inspections, which must be reported to the general manager
Comparing the temperatures of the seating areas to the temperatures in the kitchen

Correct answer: Preventing pathogen growth and spread by keeping the facilities clean on a regular basis

A primary responsibility of food managers is to ensure food safety and prevent foodborne illnesses within their establishment. This includes implementing and overseeing robust sanitation practices, such as regular cleaning and sanitizing of facilities, to prevent the growth and spread of pathogens, thereby protecting public health and maintaining a safe environment.

Question 5: The requirement for self-closing doors and tightly fitting windows in food establishments does not apply:

In climates with an average temperature of more than 70 degrees
If the property is zoned for both residential and commercial use.
When the establishment is a previously zoned residential structure
When the establishment is part of a larger structure, such as a food court (Correct answer)

Correct answer: When the establishment is part of a larger structure, such as a food court

Self-closing doors and tightly fitting windows are typically required to prevent pests and maintain environmental control. However, in a larger structure like a food court, the individual establishment often operates within a common, controlled environment. The overall building's pest control and environmental management systems usually provide the necessary protection, making the individual unit's specific door and window requirements redundant.

Question 6: Which of the following statements about floors and their coverings is false?

Only short pile carpeting should be used in areas prone to moisture or where water flushing or spray cleaning is performed. (Correct answer)
Utility pipes or lines cannot be installed near or on the floor, even if they are not visible to the public.
Floor coverings in food preparation areas, wash areas, bathrooms, and walk-in refrigerators should be light in color.
All exposed indoor wall surfaces made of brick, porous block, or concrete must be sealed to ensure proper cleaning.

Correct answer: Only short pile carpeting should be used in areas prone to moisture or where water flushing or spray cleaning is performed.

This statement is false because carpeting, regardless of pile length, is unsuitable for areas prone to moisture or requiring water flushing in food establishments. Carpeting can absorb moisture, harbor bacteria, and is difficult to clean and sanitize effectively, posing a significant food safety risk. Hard, non-absorbent, and easily cleanable surfaces are required in such areas to ensure proper hygiene.

Question 7: Following a power outage lasting more than four hours in an establishment, the following must be discarded:

Remaining condiments on tables
Vegetables that have been cooked
Excessive animal products (Correct answer)
All of the fruits

Correct answer: Excessive animal products

During a power outage, refrigerated and frozen foods, especially animal products like meat, poultry, and dairy, can quickly enter the temperature danger zone (41°F - 135°F). After four hours without proper temperature control, these potentially hazardous foods are considered unsafe to consume. Discarding them is crucial to prevent the rapid multiplication of harmful bacteria and subsequent foodborne illness.

Question 8: Oysters are considered safe to serve when they are cooked as follows:

The shells open during the cooking process. (Correct answer)
The shells are slightly cracked, but not enough to reveal their contents.
Its flesh is impossible to separate with normal fork pressure.
Its skin is smooth to the touch.

Correct answer: The shells open during the cooking process.

For shellfish like oysters, the primary indicator of proper cooking is when their shells open during the heating process. This signifies that the oyster has been exposed to sufficient heat to cook the meat inside to a safe temperature. Oysters that do not open during cooking should be discarded, as they may still harbor harmful bacteria or viruses.

Question 9: When young children are compared to healthy adults, the following is true:

They are at the same risk of foodborne illness as healthy adults.
They are at a higher risk of foodborne illness. (Correct answer)
They are only vulnerable to foodborne illnesses for the first 12-24 months of their lives, before their immune systems fully develop.
They consume less food than adults, making them less susceptible to foodborne illnesses.

Correct answer: They are at a higher risk of foodborne illness.

Young children are considered a high-risk population for foodborne illness due to their underdeveloped immune systems. Their bodies are less equipped to fight off pathogens, making them more susceptible to infections and more likely to experience severe symptoms from foodborne diseases. This vulnerability necessitates stricter food safety practices when preparing food for them.

Question 10: During a health inspection of a food establishment, the following individuals are in charge of oversight:

The establishment's general manager
The owner/operator of the establishment
The person in charge (Correct answer)
Managerial-level personnel on-site when the health inspection begins.

Correct answer: The person in charge

The 'Person In Charge' (PIC) is legally responsible for the food establishment's operations during all hours, including health inspections. This individual must be knowledgeable about food safety principles and demonstrate compliance with regulations. The PIC serves as the primary point of contact for the health inspector and is accountable for addressing any violations found.

Question 11: Which of the following symptoms may indicate that a customer is experiencing an allergic reaction?

Shortness of breath or wheezing (Correct answer)
Loss of appetite
Pain in the left arm
Coughing up blood

Correct answer: Shortness of breath or wheezing

Shortness of breath and wheezing are classic symptoms of a severe allergic reaction, specifically anaphylaxis, which affects the respiratory system. These symptoms indicate a potentially life-threatening condition requiring immediate medical attention. Recognizing these critical signs is vital for ensuring customer safety in a food establishment.

Question 12: Which of the following practices can aid in the prevention of allergic reactions?

Helping customers identify ingredients (Correct answer)
Cooking a variety of foods in the same oil
Offering home delivery
When baking biscuits, use parchment paper.

Correct answer: Helping customers identify ingredients

Providing clear and accurate information about ingredients allows customers with food allergies to make informed choices and avoid foods that contain their allergens. This practice is crucial for preventing allergic reactions, as it empowers customers to protect themselves. Food handlers should be trained to answer ingredient questions or direct customers to someone who can.

Question 13: When should a food handler with a sore throat and a fever be kept out of the operation?

When the food handler has a fever of more than 100 degrees Fahrenheit.
Prior to notifying the regulatory authority
After the food handler has had a sore throat for more than 5 days.
When the customers served are primarily from a high-risk population. (Correct answer)

Correct answer: When the customers served are primarily from a high-risk population.

A food handler with a sore throat and fever should be excluded from working with food, especially when serving high-risk populations (e.g., young children, elderly, immunocompromised individuals). These symptoms can indicate an illness that could be easily transmitted to vulnerable customers, leading to severe foodborne illness. Exclusion is critical to protect public health in such scenarios.

Question 14: Where should a food handler wash their hands after handling food?

Utility sink
A sink designated for hand washing (Correct answer)
Sink with three compartments
Sink for food preparation

Correct answer: A sink designated for hand washing

Food safety regulations mandate that handwashing must occur at a sink specifically designated for that purpose. Using utility sinks, three-compartment sinks, or food preparation sinks for handwashing can lead to cross-contamination and is unsanitary. Dedicated handwashing sinks ensure proper hygiene and prevent the spread of pathogens.

Question 15: What should the manager tell a food handler who arrives at work with diarrhea?

After each use, clean the restroom.
Only bus tables
Return home (Correct answer)
Avoid working with food.

Correct answer: Return home

A food handler experiencing diarrhea must be immediately excluded from the food establishment and sent home. Diarrhea is a symptom of many highly contagious foodborne illnesses, and allowing such an individual to work poses a severe risk of contaminating food and spreading pathogens to customers. They should not return until symptom-free for at least 24 hours.

Question 16: What should a food handler do to make putting on gloves easier?

Blow into your gloves.
Choose the proper size gloves. (Correct answer)
Coat the gloves in flour.
None of the above

Correct answer: Choose the proper size gloves.

Selecting the correct size gloves is essential for ease of use and to prevent tearing or discomfort. Properly fitting gloves are easier to put on and remove, and they are less likely to tear, which could lead to contamination. Unsanitary practices like blowing into gloves or coating them in flour should be avoided as they can introduce contaminants.

Question 17: When can a food handler who has been diagnosed with jaundice return to work?

When the regulatory authority approves it (Correct answer)
7 days after the last symptom appears
When his or her skin color returns to its natural state
One week later

Correct answer: When the regulatory authority approves it

Jaundice is a symptom of Hepatitis A, a highly contagious foodborne illness. A food handler diagnosed with jaundice must be excluded from the operation and cannot return to work until cleared by a medical practitioner and approved by the local regulatory authority. This strict protocol is necessary to prevent the spread of Hepatitis A, which can have severe public health consequences.

Question 18: Which of the following is a potential physical contaminant?

Earring (Correct answer)
Sanitizer
Sweat
Hand sanitizer

Correct answer: Earring

An earring is a physical object that can accidentally fall into food, making it a physical contaminant. Physical contaminants are foreign objects that are not naturally found in food and can cause injury or illness. Food handlers should remove all jewelry, except for a plain band ring, before working with food to prevent such contamination.

Question 19: What is the function of hand antiseptic?

Make greater use of sanitizing solutions.
Do away with the need for hand washing.
Remove the need for gloves.
Reduce the number of pathogens on your skin. (Correct answer)

Correct answer: Reduce the number of pathogens on your skin.

Hand antiseptics, or hand sanitizers, are designed to reduce the number of microorganisms on the skin. They are used *after* proper handwashing, not as a replacement for it, to further decrease pathogen levels. Antiseptics do not eliminate all pathogens and are ineffective on visibly dirty hands, emphasizing the importance of thorough washing first.

Question 20: When the following conditions apply, single-use gloves are not required:

The food handler is sensitive to latex.
Produce washing (Correct answer)
Working with cooked food
Cleaning stationary equipment

Correct answer: Produce washing

Single-use gloves are primarily required when handling ready-to-eat food to prevent direct hand contact and cross-contamination. When washing produce, the food is typically going to be further processed or cooked, and the act of washing itself is intended to remove contaminants. Therefore, gloves are not usually mandated for this task, as long as proper handwashing precedes it.

Question 21: How many people must become ill after eating the same food for a foodborne illness to be investigated as an outbreak?

2 (Correct answer)
6
10
4

Correct answer: 2

A foodborne illness outbreak is generally defined as two or more people experiencing the same symptoms after eating the same food. This threshold triggers an investigation by public health authorities to identify the source of the illness and prevent further cases. This definition helps in early detection and control of potential public health threats.

Question 22: Poor food safety can lead to the following EXCEPT:

Poor working conditions
Lower operating costs (Correct answer)
Lawsuits
Foodborne illnesses

Correct answer: Lower operating costs

Poor food safety practices invariably lead to increased operating costs, not lower ones. These costs can stem from foodborne illness outbreaks, lawsuits, fines, negative publicity, wasted food due to spoilage, and increased employee turnover. Implementing proper food safety measures, while requiring initial investment, ultimately reduces these costly risks and protects the business.

Question 23: Which of the following is NOT a food safety hazard?

Biological
Physical
Environmental (Correct answer)
Chemical

Correct answer: Environmental

Food safety hazards are typically categorized into three main types: biological (e.g., bacteria, viruses), chemical (e.g., cleaners, pesticides), and physical (e.g., glass, hair). 'Environmental' is not a recognized category of food safety hazard in this context. While the environment can contribute to hazards (e.g., dirty surfaces), it's not a hazard category itself.

Question 24: What is the most common cause of foodborne illness?

Bacteria (Correct answer)
Chemicals
Alergies
Parasites

Correct answer: Bacteria

Bacteria are the most common cause of foodborne illnesses worldwide. Many types of bacteria, such as Salmonella, E. coli, and Listeria, can contaminate food and multiply rapidly under favorable conditions, leading to illness when consumed. While viruses, parasites, and chemicals also cause foodborne illnesses, bacteria are responsible for the majority of reported cases.

Question 25: Keep food out of this temperature range due to the rapid growth of microorganisms:

41˚F - 135˚F (Correct answer)
38˚F - 130˚F
70˚F - 145˚F
32˚F - 70˚F

Correct answer: 41˚F - 135˚F

The temperature range of 41°F to 135°F (5°C to 57°C) is known as the 'temperature danger zone' because it is where pathogenic microorganisms grow most rapidly. To prevent foodborne illness, potentially hazardous foods should be kept out of this range. This means holding them at 135°F or above, or refrigerating them at 41°F or below.
