Healthy Food for a Healthy World: Healthy Food Must Be Safe Food


The Chicago Council’s campaign, “Healthy Food for a Healthy World,” builds awareness about the important role food can play in promoting health and alleviating malnutrition. We publish a blog post weekly exploring these issues and the series will culminate in the release of a new Chicago Council report at the Global Food Security Symposium 2015 on April 16. Join the discussion using #GlobalAg, and tune in to the Symposium live steam on April 16.

Food safety plays a critical role in good nutrition. Even if people eat healthy foods, contamination can hamper absorption of the nutrients, and the contaminants in food often do more harm than the good food provides. Food safety continues to prove to be a challenge for developed and developing countries, and unsafe food is linked to the deaths of an estimated 2 million people each year. As supply chains become increasingly globalized, food safety threats will continue to stretch beyond regions and affect the food security of people across borders. In the effort to ensure that everyone worldwide has access to a nutritious diet, every facet of the global food chain must consider the safety of food to be an essential component of nutrition.
Much of our food becomes contaminated before it leaves the farm gate. Mycotoxins are carcinogens produced by fungi that develop during the harvest, production and storage of grains, nuts, and other crops and have significant impact on human health. They are associated with cancer, and kidney, liver, and immune system disease, and are caused by poor harvesting and storage practices.  Aflatoxins, a type of mycotoxin, can lead to stunted growth in children and other diseases through adulthood. Aflatoxins primarily affect maize and peanuts, which are key dietary staples in developing countries. Food supplies in developing countries are also particularly vulnerable, due to poor postharvest storage practices. Mycotoxins are estimated to contaminate as much as one-quarter of all agricultural harvests worldwide. 
Foodborne illnesses also inhibit nutrition and health, particularly in developing countries due to unclean water being used to clean and process food, poor processing and storage practices, and weak regulatory systems.  As a result, foodborne illness is a significant cause of mortality worldwide, particularly among infants and young children, pregnant women, the elderly and others with weak immune systems.  An estimated 1.9 million children die annually due to diarrheal disease, to which foodborne illness is a major contributor.
But foodborne illness is not limited to low-income countries: In the United States, foodborne diseases lead to 76 million people getting sick and 5,000 deaths annually. In China, food safety issues have plagued the food industry and unnerved consumers, including a 2008 scandal when 300,000 infants were sickened by contaminated milk laced with melanine.
In order to ensure that diets are healthy and nutritious, especially in low-income countries that lack infrastructure, technology, and other inputs to effectively harvest and store to prevent contamination, it will be crucial for governments, scientists, industry leaders, and health advocates to work together to addresses the causes of unsafe food. For these reasons, food safety is the theme of World Health Day 2015, during which the World Health Organization will be advocating for food safety, from farm to plate, around the world:

Simple processing improvements in the global food chain can greatly reduce the risks of contaminated food and foodborne illnesses, such as investments in storage facilities, diagnostic tools, and training for farmers on how to prevent contamination.  Through collaborative efforts to improve food safety along the supply chain, we can ensure that nutritious foods are also safe to eat.

The Global Food and Agriculture Program aims to inform the development of US policy on global agricultural development and food security by raising awareness and providing resources, information, and policy analysis to the US Administration, Congress, and interested experts and organizations.

The Global Food and Agriculture Program is housed within the Chicago Council on Global Affairs, an independent, nonpartisan organization that provides insight – and influences the public discourse – on critical global issues. The Council on Global Affairs convenes leading global voices and conducts independent research to bring clarity and offer solutions to challenges and opportunities across the globe. The Council is committed to engaging the public and raising global awareness of issues that transcend borders and transform how people, business, and governments engage the world.
