Food Safety Basics
Keeping food safe is the foundation of any successful kitchen, whether at home or in a professional setting. The three main pillars are clean, separate, and cook. Clean surfaces and hands, keep raw foods separate from readytoeat items, and cook foods to the right internal temperature. Following these steps reduces the risk of foodborne illnesses caused by bacteria such as Salmonella, E. coli, and Listeria.
Handwashing and Personal Hygiene
Good personal hygiene starts with proper handwashing:
- Wet hands with warm water.
- Apply enough soap to cover all surfaces.
- Scrub for at least 20 secondsthink Happy Birthday twice.
- Rinse thoroughly and dry with a clean towel or disposable paper.
Repeat after handling raw meat, eggs, or any highrisk food, and always before beginning a new task.
Cooking Temperatures & Holding
Accurate temperature control is essential for killing pathogens. Use a calibrated instantread thermometer and follow these internal temperature guidelines:
| Food Type | Minimum Safe Internal Temp. | Holding Temp. |
|---|---|---|
| Poultry (whole or ground) | 165F (74C) | 140F (60C) or above |
| Ground meats (beef, pork, lamb) | 160F (71C) | 140F (60C) or above |
| Whole cuts of beef, pork, lamb | 145F (63C) + 3min rest | 140F (60C) or above |
| Fish & shellfish | 145F (63C) | 140F (60C) or above |
| Egg dishes (casseroles, quiches) | 160F (71C) | 140F (60C) or above |
| Leftovers & reheated foods | 165F (74C) | 140F (60C) or above |
Tip: Insert the thermometer into the thickest part of the food, avoiding bone or fat, for the most accurate reading.
Culinary Measurements Overview
Precision in measurement ensures consistent results, especially in baking. There are three primary systems used worldwide:
- Metric (grams, milliliters) Preferred in most professional kitchens for its accuracy.
- U.S. customary (cups, teaspoons, ounces) Common in home cooking in the United States.
- Weightbased (ounces, pounds) Useful for largescale recipes or bulk ingredients.
Dry vs. Wet Ingredients
Dry ingredients (flour, sugar, spices) are best measured by weight, while liquids (water, milk, oil) can be measured by volume or weight. Using a kitchen scale eliminates the packed vs. sifted confusion that often occurs with cup measurements.
Measuring Tools
- Digital kitchen scale Accuracy to 1g or 0.1oz.
- Measuring cups (dry) Level off with a straight edge.
- Measuring cups (liquid) Use a clear glass jug with a spout.
- Measuring spoons For small quantities; fill to the brim, then level.

Temperature Conversion
For quick reference:
- 250F = 121C
- 300F = 149C
- 350F = 177C
- 400F = 204C
- 450F = 232C
