Families flocking to join the facebook food swappers

I am continuously looking out for emerging food supply chain risk. Therefore a Sunday Times article on the 1st September covering the growth in online sites and Facebook pages for food swappers caught my interest. These sites have made it easy for people to arrange to swap food with others in their area, providing them with produce they need while ensuring any surplus they have grown themselves does not go to waste. While I like the idea I can also see that there could be a lack of food safety risk assessment. Some of  these sites are also swapping homemade products such as cakes and jams, I can imagine that these will not be complying with the food information regulation. While I personally like this idea, I can also see a lot of risks.
