In the past, the affairs happening inside one country had little influence on other countries, even the neighboring ones. Therefore, incidents of food safety only affected and spread within one country, one city, one island or one village. However, with globalization, goods and products can almost flow freely between countries, regions, and continents. So the food safety problem is therefore no longer a national or regional issue, but rather a global one．

In 1997, Avian Influenza caused widespread panic in Hong Kong．It is said that the Avian Influenza originated from Shenzhen. Some Hong Kong people blamed the chicken farm staff on the mainland for the outbreak. The staff was accused of not thoroughly checking the health condition of the chicks under their care. It resulted in Hong Kong people's anger towards chicken farm staff in Shenzhen, whose supposed negligence(疏忽)contributed to the later spread of Avian Influenza in Hong Kong．

Worse still, in Germany, people have been warned not to eat cucumbers until tests can identify the source of a deadly E. coli outbreak. The scare has spread across Europe, with 16 people so far having been killed．In many people's minds, European countries have the strictest standards and checking procedures on their food safety. But the E. coli cucumber incident brought home the reality that it was not an effective defense against such an outbreak．

These diverse food safety issues from various parts of the world are enough evidence that food safety problem is not endemic in China. In fact, food safety is not even directly related to the development level of a place, thanks, no doubt, to the connectivity of our age. If we do not maintain our vigilance(警惕), people's confidence in food safety can be destroyed instantly—even in a developed country
