Cheat Sheet

  1. Time-Temperature Control (TCS Foods) -

    Understanding the "Danger Zone" (41°F - 135°F) from the FDA Food Code is vital for preventing bacterial growth; remember to cool or reheat TCS foods within 4 hours to stay safe. Use the mnemonic "Keep It Out 41 - 135" to lock in this critical range. Regularly monitor with calibrated thermometers and log readings to spot temperature lapses early.

  2. Preventing Cross-Contamination -

    The CDC and ServSafe guidelines emphasize separating raw proteins from ready-to-eat items; use color-coded cutting boards (red for raw meat, green for produce) and dedicate utensils to each food category. Always clean and sanitize surfaces between tasks and store raw foods below cooked or ready-to-eat foods in refrigeration. A simple "Clean, Separate, Cook, Chill" routine cuts risk dramatically.

  3. HACCP Principle Review -

    Familiarize yourself with the seven HACCP principles endorsed by the USDA and international food safety bodies, including hazard analysis and critical control point identification. Use the acronym "P-D-P-C-C-M-V" (Prerequisites, Determine hazards, Critical control points, Critical limits, Monitoring procedures, Corrective actions, Verification) to map out each step. Practice drafting a mini-HACCP plan for a common dish - like chicken salad - to solidify the sequence.

  4. Personal Hygiene & Handwashing -

    ServSafe prep questions often cover the five moments for handwashing: after handling raw meat, using the restroom, touching hair, handling garbage, and before prepping food. Wash hands for at least 20 seconds with soap and warm water, per CDC standards, and dry on single-use towels. Cover cuts with a waterproof bandage and wear gloves when necessary, changing them every four hours or between tasks.

  5. Allergen Management Basics -

    Brush up on the "Big Eight" allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy) as outlined by the FDA; always verify ingredient labels and use strict cleaning protocols to avoid cross-contact. Implement clear labeling and a dedicated service area for allergen-free orders, following USDA allergen control guidance. Remember the phrase "Separate, Label, Communicate" to keep guests safe and satisfied.
