Study Notes
Sanitation Problems in Food Handling and Preparation
- Two major sanitation problems: cross contamination and food in the Food Danger Zone (5°C to 57°C or 41°F to 135°F)
- Lag phase of bacteria growth helps, but foods must be kept out of the danger zone whenever possible
Preventing Sanitation Problems
- Start with clean, wholesome foods from reputable purveyors
- Handle foods as little as possible using utensils instead of hands
- Use clean, sanitized equipment and worktables
- Clean and sanitize cutting surfaces and equipment after handling raw foods and before working on another food
- Place only food items and sanitary knives or tools on cutting boards
- Clean as you go and keep clean cloths and sanitizing solution handy
- Wash raw fruits and vegetables thoroughly
- Limit the time foods spend in the Food Danger Zone
- Keep foods covered unless in immediate use
- Observe the four-hour rule
- Cook foods to minimum internal cooking temperatures
- Taste foods properly using a clean spoon and discard utensils after use
- Boil leftover gravies, sauces, soups, and vegetables before serving
- Don't mix leftovers with freshly prepared foods
- Chill all ingredients for protein salads and potato salads before combining
- Cool and chill foods quickly and correctly
Minimum Internal Cooking Temperatures
- Minimum internal cooking temperature is the internal temperature at which microorganisms are killed
- Must be held at that temperature for a specified period for the food to be considered safe
- Measure internal temperatures in at least two or three places using a sanitary thermometer
Cooling Procedures
- Cool foods quickly to avoid spending too much time in the Food Danger Zone
- Use either the two-stage cooling method or the one-stage cooling method
- Two-stage cooling method: cool from 135°F (57°C) to 70°F (21°C) in no more than 2 hours, and then from 70°F (21°C) to below 41°F (5°C) within an additional 4 hours
- One-stage cooling method: cool to below 41°F (5°C) in no more than 4 hours
- If food does not reach the desired temperature, reheat to 165°F (74°C) and hold at that temperature for at least 15 seconds and then cool again
Temperature Control
- Temperatures between 5°C and 63°C are the danger zone for bacterial growth
- Cook food through the danger zone quickly
- Most food should be cooked to 75°C to kill bacteria
- Cool food quickly (within 90 minutes) to avoid the danger zone
- Use electronic temperature probes to measure temperatures
- Check and record refrigerator, freezer, and chill cabinet temperatures at least once a day
Preparation
- Monitor the time that food spends at kitchen temperatures and keep it to a minimum
- Prepare large amounts in batches, keeping the majority of the food refrigerated until needed
- Core temperature of food should not go above 8°C
- Defrost frozen food in a specific thawing cabinet or in a deep tray, covered with film and labeled
Cooking
- Cooking food to a core temperature of 75°C for two minutes will kill most bacteria
- Higher temperatures may be required for certain dishes or customer requirements
- Always cook to the higher recommended temperature when meat has been boned/rolled or minced, or where the food is part of a made-up dish
Chilling
- Cool food to 8°C within 90 minutes to prevent bacterial multiplication and spore growth
- Use a blast chiller to cool food quickly
Freezing
- Freeze food to --18°C within 4 hours to prevent bacterial growth and spore growth
- Use a proper blast freezer to freeze food quickly
Reheating
- Reheat previously cooked food to at least 75°C (82°C in Scotland)
- Maintain the temperature for at least two minutes and reheating must only be done once
Holding for Service, Serving, and Transporting
- Cooked food being held for service, served, or transported must be kept above 63°C for hot food or below 5°C for cold food
Food Spoilage
- Food spoilage is caused by the natural breakdown of the food by spoilage organisms
- Signs of spoilage include mould, slimy or over-wet/over-dry food, sour smell or taste, discoloured and wrinkled food, or texture changes
- Poor storage, handling, or contamination can also cause food spoilage
