1Which bacterium is most commonly linked to undercooked poultry and raw eggs?

A.Salmonella

B.Listeria monocytogenes

C.Clostridium botulinum

D.Vibrio

Explanation: Salmonella is most often associated with raw or undercooked poultry, eggs and products made from them. Cooking poultry to an internal temperature of 74 degrees C (pieces) destroys it. Symptoms include diarrhea, fever and abdominal cramps.

2E. coli O157:H7 is most strongly associated with which food?

A.Canned tomatoes

B.Undercooked ground beef

C.White bread

D.Boiled potatoes

Explanation: E. coli O157:H7 is most strongly linked to undercooked ground beef, where grinding spreads surface bacteria throughout the meat. Ground beef must reach an internal temperature of 71 degrees C. It can cause severe bloody diarrhea and, in some cases, kidney damage.

3What is the temperature danger zone used in Ontario food safety guidance?

A.0 degrees C to 40 degrees C

B.4 degrees C to 60 degrees C

C.10 degrees C to 50 degrees C

D.20 degrees C to 80 degrees C

Explanation: In Ontario the temperature danger zone is 4 degrees C to 60 degrees C. Within this range harmful bacteria multiply most rapidly. Keeping cold food at 4 degrees C or colder and hot food at 60 degrees C or hotter keeps food out of the danger zone.

4Under Ontario Regulation 493/17, what staffing requirement applies to a food service premise during operating hours?

A.Every employee must hold a food handler certificate

B.At least one certified food handler or supervisor must be on site

C.A public health inspector must be present

D.No certification is required at any time

Explanation: O. Reg. 493/17 requires every food service premise to ensure at least one food handler or supervisor who has completed food handler training is on site during every hour it operates. Not every employee must be certified, but one trained person must always be present.

5What is the minimum internal cooking temperature for chicken pieces and ground poultry?

A.63 degrees C

B.70 degrees C

C.74 degrees C

D.82 degrees C

Explanation: Poultry pieces and ground poultry must reach an internal temperature of 74 degrees C. Only whole poultry must reach the higher figure of 82 degrees C. Using a probe thermometer in the thickest part confirms the food is safe.

6A refrigerator in a food premise should be kept at what temperature or colder?

A.4 degrees C

B.10 degrees C

C.0 degrees C

D.minus 18 degrees C

Explanation: Refrigerators should be kept at 4 degrees C or colder to keep food out of the danger zone and slow bacterial growth. Freezers should be kept at minus 18 degrees C or colder. Staff should check fridge thermometers regularly.

7What is the difference between cleaning and sanitizing?

A.They mean the same thing

B.Cleaning removes visible dirt; sanitizing reduces bacteria to safe levels

C.Sanitizing removes visible dirt; cleaning kills all bacteria

D.Cleaning sterilizes surfaces completely

Explanation: Cleaning removes visible food, grease and dirt from a surface, while sanitizing reduces the number of bacteria on an already-clean surface to a safe level. A surface must be cleaned before it is sanitized, because sanitizers do not work well on dirty surfaces.

8Which sanitizer concentration is approved for chlorine (bleach) solution on food contact surfaces?

A.10 ppm

B.100 ppm

C.500 ppm

D.1000 ppm

Explanation: A chlorine sanitizing solution of about 100 ppm is approved for food contact surfaces. Quaternary ammonium is used at 200 ppm and iodine at 25 ppm. Test strips should be used to confirm the correct concentration.

9What is the single most important thing a food handler can do to prevent the spread of germs?

A.Wear a hat

B.Wash hands properly and often

C.Use cold water only

D.Work quickly

Explanation: Proper and frequent handwashing is the single most effective action a food handler can take to prevent contaminating food. Hands should be washed with soap and warm running water for at least 20 seconds, especially after using the washroom and handling raw foods.

10Norovirus outbreaks in food premises are most often caused by what?

A.Storing canned goods too long

B.An infected food handler contaminating ready-to-eat food

C.Using too much sanitizer

D.Cooking food above 74 degrees C

Explanation: Norovirus is highly contagious and is frequently spread when an infected food handler contaminates ready-to-eat food, often through poor handwashing after using the washroom. Food handlers with vomiting or diarrhea should be excluded from work until cleared.

About the Ontario Food Handler Exam

The Ontario Food Handler Certification shows that a person has the knowledge and skills to handle food safely in a food premise. It is the recognized food safety qualification used to satisfy Ontario Regulation 493/17 (Food Premises) under the Health Protection and Promotion Act, which requires every food service premise to have at least one certified food handler or supervisor on site during every hour it operates. Candidates study a Ministry of Health approved manual covering foodborne illness and microbiology, the temperature danger zone and safe Celsius cooking, holding, cooling and reheating temperatures, cross-contamination prevention, personal hygiene and handwashing, receiving and storage, cleaning and sanitizing, pest control and Health Canada priority allergens. Certification is earned by passing a closed-book multiple-choice exam with a mark of at least 70%, and the certificate is valid for five years and accepted by all Ontario public health units.

Assessment

A standardized closed-book exam of typically 50 multiple-choice questions (some providers use roughly 50 to 60) covering foodborne illness, temperature control, cross-contamination, personal hygiene, cleaning and sanitizing, pest control, allergens and Ontario food safety law.

Time Limit

About 60 minutes. The proctored exam generally allows up to one hour to answer the multiple-choice questions.

Passing Score

A minimum grade of 70% is required to pass. On a 50-question exam that is 35 correct answers; candidates who pass receive a certificate and wallet card valid for five years.

Exam Fee

Fees vary by approved provider and public health unit, typically from about $10 to $65 (HST included). Some health units offer the course free with a small exam fee; some online providers charge roughly $25 to $50. (Ontario public health units and other providers recognized by the Ontario Ministry of Health.)

Ontario Food Handler Study Tips from Top Performers

1Memorise the key Celsius temperatures: danger zone 4 to 60 degrees C, whole poultry 82, poultry pieces and mixtures 74, ground beef and pork 71, fish 70, fridge 4 or colder, freezer minus 18.

2Learn each major pathogen by its high-risk food and key fact, for example Salmonella with poultry and eggs, E. coli O157:H7 with undercooked ground beef, and Listeria with deli meats and soft cheese.

3Know that cleaning removes visible dirt while sanitizing reduces bacteria, and remember the approved concentrations: chlorine 100 ppm, quaternary ammonium 200 ppm and iodine 25 ppm with adequate contact time.

4Understand the Ontario law: O. Reg. 493/17 requires at least one certified food handler or supervisor on site during every operating hour, and public health inspectors check certificates.

5Practise the two-hour rule and two-stage cooling, and remember to reheat previously cooked food to 74 degrees C for at least 15 seconds before hot holding at 60 degrees C or hotter.

6Review the Health Canada priority allergens and store ready-to-eat foods above raw meats, using FIFO so older stock is used first.
