- What is SFBB (Safer Food, Better Business)?
- Safer Food, Better Business (SFBB) is a practical food safety management pack developed by the UK Food Standards Agency (FSA). It helps small catering and retail businesses comply with food hygiene regulations through documented procedures across cooking, cleaning, chilling, cross-contamination, and daily opening/closing checks.
POSTERFree How to Calibrate a Thermometer Guide
Calibrate kitchen probe thermometers using ice slurry and boiling water. Free step-by-step calibration guide with ±1.0°C FSA accuracy tolerances.
Calibrating a food thermometer verifies that temperature probes provide accurate readings to guarantee microbiological food safety. Commercial kitchens calibrate probes using two standard scientific reference methods: the Ice-Point Slurry method (target 0.0°C, acceptable range -1.0°C to +1.0°C) and the Boiling-Water method (target 100.0°C, acceptable range 99.0°C to 101.0°C at sea level). Probes with error exceeding ±1.0°C must be recalibrated or replaced.

UK Food Standards Agency (FSA) regulations require kitchen surface sanitisers to remain visibly wet on food-contact counters for the certified dwell time (typically 30 to 60 seconds) to destroy 99.999% of bacteria.

Practical due diligence procedures, regulatory compliance steps, and EHO audit verification guidelines for UK hospitality businesses.
UK Statutory Due Diligence Framework
Under Section 21 of the Food Safety Act 1990, a food business operator has a defense of due diligence if they prove that all reasonable precautions were taken and all due diligence was exercised to prevent food safety offenses.
Documented logs like the How Do You Calibrate A Thermometer Poster provide contemporaneous proof of monitoring required by Regulation (EC) No 852/2004 (retained UK law). Local council Environmental Health Officers (EHO) evaluate these records when scoring the "Confidence in Management" category of the Food Hygiene Rating Scheme (FHRS).
Official FSA Record-Keeping Guidance & Due Diligence
Under UK Food Standards Agency (FSA) Safer Food, Better Business (SFBB) standards and Article 5 of Regulation (EC) No 852/2004, food business operators are required to maintain contemporaneous, accurate operational records.
- Contemporaneous logging: Kitchen logs must reflect actual checks performed during opening, active service, and closing rather than retrospective estimates.
- Corrective action logs: Whenever a critical limit is breached, document the specific corrective measure taken (e.g. food discarded, chilled, or reheated) with staff initials.
- Statutory due diligence defense: Retaining completed daily sheets for a minimum of 6 to 12 months supports the statutory defense under Section 21 of the Food Safety Act 1990. Official guidance is available at food.gov.uk.
Step-by-Step Operational Routine
Operational Step 1
Prepare ice bath: fill a glass beaker with crushed ice and add cold water until ice is saturated; stir and let sit for 2 minutes.
Operational Step 2
Test ice point: insert probe 5 cm into slurry without touching glass walls; wait for reading to stabilize at 0.0°C (±1.0°C tolerance).
Operational Step 3
Prepare boiling water: bring a deep saucepan of clean water to a rapid rolling boil on the cookline range.
Operational Step 4
Test boiling point: immerse probe tip into center of boiling water; confirm stabilized reading reads 100.0°C (±1.0°C tolerance).
Operational Step 5
Document and adjust: record variance in your monthly calibration log; adjust manual hex calibration screw or replace unit if variance exceeds ±1°C.
Procedures align with UK Food Standards Agency (FSA) Safer Food, Better Business (SFBB) catering guidance and the Food Information Regulations 2014. Review official advice at food.gov.uk.
