10 Facts on Food Safety

February 28, 2018 | by

Over 200 diseases are caused by unsafe food that contains bacteria or chemical substances.

Awareness is the first step to prevention. The World Health Organization has published these 10 facts about food safety:


1. 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.

2. 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.

3. Foodborne diseases affect vulnerable people harder than others

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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.
