There are several food safety regulations you’ll need to follow which will cover the way food is stored. This includes making sure produce is temperature controlled and that any food prep areas are managed hygienically.
You’ll also need to follow strict regulations when it comes to food labelling, such as listing all ingredients and specifying use by dates.
For details of the rules you’ll need to work to, speak to your local authority’s environmental health department. They’ll be able to help you with queries about food hygiene standards and tell you what’s expected. Your local trading standards office can also help with understanding food labelling requirements. The Food Standards Agency also has a section dedicated to business guidance.
You may also want to consider a product liability insurance policy, to protect you in the event of a claim as a result of a product that you have sold. In particular, this type of policy can provide cover for claims of food poisoning if you’re found to have been unintentionally negligent i.e. accidentally not following food safety standards.
