The 2014 Commonwealth Games offers the "perfect platform" to showcase Scottish produce, the environment secretary has said.

With more than two million meals to be served over the course of the event in Glasgow, organisers have urged the Scottish food and drink industry to compete for contracts worth millions of pounds.

Craig Lear, Glasgow 2014's head of catering, cleaning and waste, will highlight the dozens of wide-ranging services contracts available at the Scotland Food and Drink AGM in Perth on Friday.

He will say: "For 25 days of the Games period, including the 11 days of competition, there will be more than two million meals made for athletes, team officials, technical officials, the media, the workforce, the Games Family and for spectators.

"This is the biggest event that the Scottish catering, cleaning and waste industry will have ever seen, and it's time to get excited about what opportunities will be available.

"The Games will be a spectacular sporting event which showcases the city and the nation on an international stage, and the race for those in the catering, cleaning and waste industries in Scotland will begin in late 2012 when we go out to tender for dozens of contracts.

"The opportunity to win business, raise international ambitions and deliver growth could be enormous, but like the event itself, only the best will win gold."

Over the course of Glasgow 2014, more than 100 tonnes of fruit and vegetables, 10,000 loaves of bread and 60 tonnes of potatoes as well as huge amounts of other produce will be needed.

Rural Affairs and Environment Secretary Richard Lochhead said: "Scottish food and drink is world renowned as high quality. Therefore the Commonwealth Games coming to Glasgow offers the perfect platform to showcase Scottish produce - as well as providing a fantastic opportunity for Scottish businesses to get involved.

"I would encourage Scottish companies to bid for contracts so that their products can help fuel athletes from around the world to success in 2014."

The opening ceremony of the Glasgow 2014 Commonwealth Games will be held on July 23 2014.

It will mark the beginning of 11 days of sporting competitions between 71 Commonwealth nations and territories.
