For any food business, safety is non-negotiable. However, even with the best intentions, unforeseen incidents can occur. This is where the concept of "Due Diligence" becomes the most critical pillar of your food safety management system.

What is due diligence?

At its core, due diligence is the legal principle of taking all reasonable precautions and exercising all due care to avoid committing an offence. It is about demonstrating that you have proactively identified risks and taken every necessary step to prevent them from happening.

What does due diligence mean in food safety?

In the context of a food business, due diligence means you can prove you have done everything humanly possible to ensure the food you produce, serve and sell is safe for consumption. It is about moving from "hoping nothing goes wrong" to "having a documented, verifiable system that prevents things from going wrong."

What food safety laws refer to due diligence?

In the UK, the Food Safety Act 1990 is the primary legislation that codifies the due diligence defence. Section 21 of the Act states that it is a defence for a person to prove that they took all reasonable precautions and exercised all due diligence to avoid the commission of an offence. This is supported by the Food Safety and Hygiene (England) Regulations 2013 and equivalent legislation in Scotland, Wales, and Northern Ireland, which mandate the implementation of a food management system run on HACCP (Hazard Analysis and Critical Control Point) principles.

How does a food business prove due diligence?

Proving due diligence relies entirely on documentation and evidence. To build a robust defence, your business must demonstrate:

• A Solid HACCP Plan: You have identified all hazards (biological, chemical, physical, and allergenic) and implemented controls at critical points.
• Comprehensive Records: Daily logs showing temperature checks, cleaning schedules, supplier audits, and pest control reports etc.
• Staff Training: Produce evidence that every team member is trained and supervised to the appropriate level for their role, and schedule refresher training regularly.
• Supplier Management: Proof that you only source ingredients from approved, reputable suppliers.
• Corrective Actions: Documentation showing that when a problem did arise (e.g., a fridge temperature spike), you identified it immediately and took corrective action to fix it.

What is a due diligence defence?

A due diligence defence is a legal argument that is used in court if a food business is prosecuted for a food safety breach. If a business can provide sufficient evidence that they followed their own documented procedures, trained their staff, and maintained all safety logs, a judge may find that they acted with due diligence despite the incident.

Essentially, it is your business’s "safety net." By embedding due diligence into your daily culture rather than just viewing it as paperwork, you don't just protect yourself legally; you also protect your customers and the reputation of your brand.
