This is an area that is largely enforced by Trading  Standards Officers, except for Use-By dates where Environmental Health staff has  powers as well. It can be a very complex subject and if in any doubt about  anything described below, contact Trading Standards at Kent County Council for advice.
i. Weights
As a general rule, most loose foods such  as fruit and vegetables must be sold by net weight, using approved weighing  equipment. If food is pre-packed, the weight must be marked on the pack, (you  can show both imperial and metric  weights). Some pre-packed foodstuffs must be sold in specific quantities; these  include potatoes, jams, honey, dried fruit and dried vegetables.
ii. Labelling
Food labelling can be very specific but as a general rule,  the following advice applies:
Loose foods and foods pre-packed by you  must display the name of the food, which must be accurate and unambiguous. You  will also need to indicate any additives used, such as flavouring, flavour  enhancers, preservatives, flour improvers, colours, anti-oxidants or  sweeteners.
Pre-packed foods, other than those you have pre-packed  yourself, may require:
- A 'Best Before' or 'Use By' date. 'Best Before' dates are mainly for foods  whose quality decreases over a medium to long shelf life, such as cakes and  biscuits. 'Use By' dates are for foods which deteriorate rapidly and may end up  posing a risk to health, such as chilled meat products. 
 
- A list of ingredients. 
 
- The name and address of the person putting the product into circulation. 
 
- Any storage conditions. 
 
- Any previous process or treatment, for example "previously  frozen".
 
 There are specific requirements for declaring the  percentages of certain ingredients. For instance, where an ingredient is  highlighted in the name of a food, e.g. "Apple and ginger chutney" the  percentages of apple & ginger would have to be declared on the  label.
There are also specific requirements regarding the inclusion of  genetically modified and irradiated ingredients.
Meat products require a  label showing their minimum meat content or, in the case of cured meat, their  added water content. For Farmers' Markets, this is a chance for exploiting any  superior meat content of your product over those that are available in the high  street.
iii. Prices
Prices must be clearly displayed, either  per item or per weight, litre, square metre or metre as appropriate. The price  can be displayed as a list at the stall or shown directly on the  product.
iv. Business Names
While it is usually good practice  to display your full name and address on your stall, if you are trading in  someone else's name, you must clearly display to customers the business name and  address of the owners.
v. Other Considerations
Some foods, such  as jams and fruit juices, have specific Trading Standards requirements. This  leaflet does not cover all aspects of the law and just to re-emphasize the  advice of the opening paragraph in this section, your local Trading Standards  officer at Kent County Council will be happy to talk to you
