What are the new political implications of food safety?

This is not ONE question,  but let us take it from governmental view, it takes it from two directions, the first one is the food industries  , while the government supports these industries to raise the level of compliance with the regulation and global specification and work in continual improvement cycle. The second one is the consumers themselves , the government do it by two way either by protect them from unknown food industries organization, or by increasing the food safety awareness for customer.

Recently, third-party certification (TPC) has emerged as a significant regulatory mechanism in the global agrifood system. It reflects a broader shift from public to private governance. Traditionally, government agencies were responsible for monitoring food safety and quality standards. However, the globalization of the agrifood system, the consolidation of the food retail industry, and the rise in private retailer standards have precipitated a shift in responsibility for this task to third-party certifiers. This development is reconfiguring social, political, and economic relations throughout the contemporary agrifood system. In discussing the rise of TPC, this paper focuses on the role and implications for three key stakeholder groups: supermarket chains, producers, and non-governmental organizations. We conclude that TPC reflects the growing power of supermarkets to regulate the global agrifood system. At the same time, TPC also offers opportunities to create alternative practices that are more socially and environmentally sustainable.
