For example, WHO has been at the forefront of efforts to eradicate smallpox, combat polio, and manage the global response to pandemics like COVID-19. Through vaccination campaigns and disease surveillance, WHO aims to reduce the global burden of infectious diseases.
• Non-Communicable Diseases (NCDs): WHO also focuses on preventing and managing chronic diseases such as heart disease, cancer, and diabetes. It provides guidelines on lifestyle changes, tobacco control, nutrition, and mental health, advocating for policies that reduce the risk factors for these diseases.
• Global Health Partnerships: WHO collaborates with other UN agencies, governments, and non-governmental organizations (NGOs) to implement health programs and initiatives. WHO is involved in global health partnerships such as the Global Fund to Fight AIDS, Tuberculosis, and Malaria and the Gavi Vaccine Alliance.

1.3 WHO’s Role in Global Health Regulations

• International Health Regulations (IHR): The IHR is an international legal framework developed by WHO to prevent the spread of diseases across borders. The IHR provides guidelines for responding to public health emergencies, including outbreaks of infectious diseases. The IHR also sets requirements for health measures at points of entry, such as airports and ports, to minimize the spread of diseases.
• Setting Guidelines for Food Safety: WHO works with other organizations to set global food safety standards and guidelines. It collaborates with Codex and the World Trade Organization (WTO) to establish standards that protect consumers from unsafe food and ensure safe trade practices.

2. What Is Codex Alimentarius Commission (Codex)?

The Codex Alimentarius Commission (Codex) is an international body established by the United Nations Food and Agriculture Organization (FAO) and the World Health Organization (WHO). Codex develops international food safety standards, guidelines, and codes of practice to protect consumer health and ensure fair practices in the international food trade. It was founded in 1963 and is headquartered in Rome, Italy.

2.1 Codex’s Mandate and Functions

• Setting Food Safety Standards: Codex’s primary function is to develop science-based standards and guidelines for food safety. These standards cover all aspects of food production, from farm to table, including food labeling, hygiene, additives, contaminants, and veterinary drug residues in food. Codex standards are used by governments around the world to regulate food safety and trade.
• Protecting Consumer Health: Codex works to protect consumers from unsafe food by setting limits on harmful substances in food, such as pesticide residues, food additives, and contaminants. Codex also provides guidelines for food labeling and the use of food claims to ensure that consumers can make informed choices about the food they eat.
• Facilitating International Trade: Codex helps ensure that food products meet international standards and can be traded across borders without compromising safety. By setting consistent and internationally recognized food standards, Codex reduces barriers to trade and promotes fair practices in the global food market.

2.2 Codex’s Role in Food Safety and Trade

• Risk Assessment and Science-Based Standards: Codex relies on scientific evidence to develop its food safety standards. The commission works with experts in food safety, toxicology, microbiology, and public health to assess potential risks and develop guidelines that are based on the best available science.
• Food Safety Guidelines: Codex provides guidelines on various aspects of food safety, including proper handling, storage, and transportation of food products. For example, Codex provides guidelines on safe handling of meat and poultry, the use of food additives, and food labeling requirements. These guidelines help ensure that food is safe for consumption and meets quality standards.
• Codex and WTO Dispute Resolution: Codex standards play a key role in international trade agreements. The World Trade Organization (WTO) often refers to Codex standards when resolving trade disputes related to food safety. Countries that adopt Codex standards are less likely to face trade barriers related to food safety concerns, as these standards are widely recognized and respected globally.

2.3 Key Areas of Codex Work

• Food Additives and Contaminants: Codex sets international standards for food additives, including preservatives, colorants, and flavorings, as well as limits for contaminants like pesticides, heavy metals, and mycotoxins. These standards help protect consumers from harmful substances in their food.
• Food Labeling: Codex provides guidelines for food labeling that promote transparency and consumer information. These guidelines cover the labeling of ingredients, nutritional information, allergens, and claims like "organic" or "gluten-free." The aim is to ensure that consumers can make informed decisions about the food they purchase.
• Microbiological Criteria: Codex establishes microbiological standards for food safety, including acceptable levels of pathogens like Salmonella and E. coli. These standards help countries ensure that food products are free from harmful microorganisms and safe to eat.

3. The Relationship Between WHO and Codex

WHO and Codex work closely together to promote global food safety and health standards. As the leading global health authority, WHO provides scientific expertise and health guidance on food safety issues, while Codex works to develop practical, science-based standards and guidelines for food production and trade. Together, WHO and Codex play complementary roles in ensuring the safety and quality of the food supply worldwide.
