The World Health Day is a global health awareness day celebrated every year on 7 April, under the sponsorship of the World Health Organization (WHO).
It is seen as an opportunity by the organization to draw worldwide attention to a subject of major importance to global health each year.
The WHO is promoting improvement of food safety as part of the 2015 World Health Day campaign. Unsafe food — food containing harmful bacteria, viruses, parasites or chemical substances — is responsible for more than 200 diseases, and is linked to the deaths of some 2 million people annually, mostly children. Changes in food production, distribution and consumption; changes to the environment; new and emerging pathogens; and antimicrobial resistance all pose challenges to food safety systems.
