Whether the event is a small community gathering or a large scale food market, it is the responsibility of the event organiser to ensure that the food and drink produced and sold or given away is safe.
The requirements that need to be in place at an event will be dependent upon the nature of the event and the types of food business in attendance. The Chartered Institute of Environmental Health has produced National Guidance for Outdoor and Mobile Catering. Event organisers should ensure that all traders comply with this guidance.
It is strongly recommended that event organisers only allow businesses with a Food Hygiene Rating of 3 and above to trade. This rating should be clearly displayed for the public to see. A rating of 3 and above ensures that the business is registered with their local environmental health department and is operating to a high standard. You can check the Food Hygiene Rating of a business at Food Standard Agency
