Food Handler Training — Module 8: Cooking Temperatures

This is the module that will show up on your exam more than any other. Safe cooking temperatures are the single most tested topic on the Ontario Food Handler Certification exam. If you memorize one chart from this entire course, make it the one in this module.

The Cooking Temperature Chart — Memorize This

These are Health Canada's minimum safe internal cooking temperatures. Every number matters.

Why These Temperatures Matter

74C kills Salmonella. It kills Campylobacter. It kills E. coli. These pathogens are destroyed at specific temperatures, and the numbers above represent the points at which food reaches guaranteed safety. Below these temperatures, bacteria survive. Above, they die. It is that simple.

Notice the pattern: ground meats require higher temperatures than whole cuts of the same animal. Ground beef needs 71C while a beef steak needs only 63C. Why? Grinding takes bacteria that live on the surface of the meat and distributes them throughout the entire product. A steak only has bacteria on the outside — searing the surface kills them. A burger has bacteria all the way through.

Never Wash Raw Chicken

This catches people off guard. Many home cooks wash their chicken before cooking. In a professional food safety context, this is one of the worst things you can do.

When you rinse raw chicken under running water, you splash Salmonella and Campylobacter onto everything within reach — the sink, the countertop, nearby utensils, your clothing, other food. Research shows water droplets carrying these bacteria can travel up to 1 meter (3 feet) from the point of contact.

Cooking to 74C kills all pathogens on and in the chicken. Washing does not kill anything — it spreads contamination to surfaces that will not be cooked.

Thermometer Use — The Right Way

A cooking temperature is only as reliable as the thermometer reading it. Improper thermometer use gives false readings, and false readings can mean serving undercooked product.

Where to probe:

• Insert the probe into the thickest part of the meat, all the way to the center
• For whole chicken or turkey: insert into the innermost part of the thigh, avoiding bone
• For thin items like chicken cutlets or burger patties: insert from the side
• Never touch bone — bone conducts heat faster than meat and gives a falsely high reading
• Do not touch fat or gristle — same issue

Let the thermometer stabilize for 15 to 20 seconds before reading. Check every piece in a batch — temperatures vary across items. Clean and sanitize the probe between uses, especially between raw and cooked products. Always use a calibrated digital probe thermometer — not pop-up timers, not your hand, not "it looks done."

Calibrating Your Thermometer — The Ice Bath Method

Thermometers drift over time. Calibration ensures they are still accurate. The ice bath method is the standard, and you need to know it for the exam.

1. Fill a glass with crushed ice and add cold water to fill the gaps
2. Stir the ice water and let it sit for 1 minute
3. Insert the thermometer probe into the center of the ice water, not touching the sides or bottom of the glass
4. Wait for the reading to stabilize
5. The thermometer should read 0C (32F)
6. If it does not, adjust according to the manufacturer's instructions

Calibrate at the start of every shift, whenever a thermometer is dropped, and any time a reading seems off.

Reheating — Not the Same as Hot Holding

This distinction trips up a lot of exam candidates. Reheating and hot holding are two different things.

Reheating: Bringing leftover food back up to 74C (165F) for a minimum of 15 seconds. Must reach this temperature within 2 hours. If it does not reach 74C within 2 hours, discard it.

Hot holding: Maintaining already-hot food at 60C (140F) or above. Hot holding equipment — steam tables, heat lamps, warming cabinets — is designed to maintain temperature, not to raise it. You cannot use hot holding equipment to reheat food. The food must already be at 74C before it goes into holding.

Marination Safety

Marinating adds flavor, but it also creates food safety risks if done incorrectly.

• Always marinate in the refrigerator — never at room temperature. Marinating chicken on the counter is marinating it in the danger zone.
• Never reuse marinade that has been in contact with raw meat. The marinade now contains raw meat juices, Salmonella, Campylobacter — whatever was on that chicken is now in the liquid. If you want to use the marinade as a sauce, set aside a portion before it touches raw product, or boil the used marinade thoroughly.
• Use food-grade, non-reactive containers (stainless steel, food-grade plastic, glass). Not aluminum — acidic marinades react with it.

Preparation Best Practices for Meat Processing

• Work in small batches. Pull only what you need from the cooler. Minimize time in the danger zone.
• Separate raw and ready-to-eat. Different prep areas, cutting boards, and utensils.
• Mechanical tenderization (blade or needle) creates the same risk as grinding — treat tenderized steaks like ground meat and cook to 71C.
• Stuffed poultry: Stuffing must reach 74C internally. The safer option is cooking stuffing separately.
