1. Saturated fast food markets in the developed economies. The fast food market in the developed countries is already overcrowded by so many fast food restaurant chains and this already proves to be a threat to KFC as it finds it hard to grow in the developed economies.
2. Trend towards healthy eating. Due to government and various organizations attempts to fight obesity, people are becoming more conscious of eating healthy food rather than what KFC has mainly to offer in its menu.
3. Local fast food restaurant chains. Local fast food restaurants can often offer a more local approach to serving food and menu that exactly represents local tastes. Although KFC does a great job in adapting its own menu to local tastes, the rising number of local fast food chains and their lower meal prices is a threat to KFC.
4. Currency fluctuations. KFC receives part of its income from foreign operations. That income has to be converted into dollars and may affect the business' profits, especially when the dollar is appreciating against other currencies.
5. Lawsuits against KFC. KFC has already been sued for many times and lost quite a few lawsuits. Lawsuits are expensive as they require time and money. As KFC continues to operate more or less the same way, there is high probability for more expensive lawsuits to come.
