World Health Day 2015: Food safety


7 April 2015 - World Health Day


“From farm to plate, make food safe.”


Over 200 diseases are caused by unsafe food containing harmful bacteria, parasites, viruses, chemical substances.2 millionIt is estimated that two million deaths occur every year from contaminated food or drinking water.






Unsafe food is linked to the deaths of an estimated 2 million people annually – including many children. Food containing harmful bacteria, viruses, parasites or chemical substances is responsible for more than 200 diseases, ranging from diarrhoea to cancers.
New threats to food safety are constantly emerging. Changes in food production, distribution and consumption; changes to the environment; new and emerging pathogens; antimicrobial resistance - all pose challenges to national food safety systems. Increases in travel and trade enhance the likelihood that contamination can spread internationally.



10 facts on food safety
More than 200 diseases are spread through food.
Millions of people fall ill every year and many die as a result of eating unsafe food. Diarrhoeal diseases alone kill an estimated 1.5 million children annually, and most of these illnesses are attributed to contaminated food or drinking water. Proper food preparation can prevent most foodborne diseases.
Contaminated food can cause long-term health problems.
The most common symptoms of foodborne disease are stomach pains, vomiting and diarrhoea. Food contaminated with heavy metals or with naturally occurring toxins can also cause long-term health problems including cancer and neurological disorders.
Foodborne diseases affect vulnerable people harder than other groups.
Infections caused by contaminated food have a much higher impact on populations with poor or fragile health status and can easily lead to serious illness and death. For infants, pregnant women, the sick and the elderly, the consequences of foodborne disease are usually more severe and may be fatal.
There are many opportunities for food contamination to take place
Today’s food supply is complex and involves a range of different stages including on-farm production, slaughtering or harvesting, processing, storage, transport and distribution before the food reaches the consumers.
Globalization makes food safety more complex and essential.
Globalization of food production and trade is making the food chain longer and complicates foodborne disease outbreak investigation and product recall in case of emergency.
Food safety is multisectoral and multidisciplinary
To improve food safety, a multitude of different professionals are working together, making use of the best available science and technologies. Different governmental departments and agencies, encompassing public health, agriculture, education and trade, need to collaborate and communicate with each other and engage with the civil society including consumer groups.
Food contamination also affects the economy and society as a whole.
Food contamination has far reaching effects beyond direct public health consequences – it undermines food exports, tourism, livelihoods of food handlers and economic development, both in developed and developing countries.
Some harmful bacteria are becoming resistant to drug treatments.
Antimicrobial resistance is a growing global health concern. Overuse and misuse of antimicrobials in agriculture and animal husbandry, in addition to human clinical uses, is one of the factors leading to the emergence and spread of antimicrobial resistance. Antimicrobial-resistant bacteria in animals may be transmitted to humans via food.
Everybody has a role to play in keeping food safe.
Food safety is a shared responsibility between governments, industry, producers, academia, and consumers. Everyone has a role to play. Achieving food safety is a multi-sectoral effort requiring expertise from a range of different disciplines – toxicology, microbiology, parasitology, nutrition, health economics, and human and veterinary medicine. Local communities, women’s groups and school education also play an important role.
Consumers must be well informed on food safety practices.
People should make informed and wise food choices and adopt adequate behaviors. They should know common food hazards and how to handle food safely, using the information provided in food labelling.





Five keys to safer food
Food safety is a shared responsibility. It is important to work all along the food production chain – from farmers and manufacturers to vendors and consumers. For example, WHO’s Five keys to safer food offer practical guidance to vendors and consumers for handling and preparing food:
Key 1: Keep clean
Key 2: Separate raw and cooked food
Key 3: Cook food thoroughly
Key 4: Keep food at safe temperatures
Key 5: Use safe water and raw materials.
