How to Implement the Recipe Calculator in Your Commercial Kitchen
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 Recipe Calculator 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.
