London, November 22, 2001 (ResearchWire) - The French authorities have a growing battle on their hands. Demand for high quality foods skyrockets each Christmas, as does the amount of sub-standard 'luxury' food hitting the shelves.

Sales of fine foods in France are continuing to grow by nearly 3% per year, making customer protection in this sector more important and more difficult each year.
