Recently, food safety has been receiving major attention due to trends such as globalization of the food supply, rapid urbanization, complexity of food preparation, increasing numbers of at risk people, changes in food consumption, climate change and emergence of new or antimicrobial-resistant pathogens.
Furthermore, there is a high incidence of foodborne diseases in both developed and developing countries, which has negative impact on public health and economic productivity. According to 2015 World Health Organization (WHO) estimates, foodborne illnesses are making 600 million people ill and kill 420,000 people — including 125,000 children under five years old — per year worldwide.
There are strong linkages between food safety, food security, nutrition, health, trade, poverty and development. Enhancing food safety is an important measure to achieve food security.
Food safety is a multidisciplinary issue and must be addressed while taking into account the roles of multiple stakeholders including the food industry, governments and consumers. It is important for each country to discuss the risks, benefits and costs of investing in food safety. Risks also vary from country to country.
