On the occasion of the World health Day, UN officials raised concerns over challenges of food safety worldwide. The officials said that there is an immense need to make joint efforts by multi-sectors from food production to food supply chain.

UN Secretary-General Ban Ki-moon said it is very important for people to ask themselves how safe their food is. He said that unsafe food is not properly reported most times. World Health Organization (WHO) has to say that unsafe food is responsible for causing more than 200 diseases, including diarrhea, cancers.

"Changes to the way food is produced, distributed and consumed, the emergence of resistant bacteria, and increases in travel and trade make it difficult to manage pathogens and contaminants once they are in our food supply", said Ban Ki-moon.

The food supply is expanding around the world, which is why there is a strong need to strengthen food safety systems within and among countries.

WHO Director-General Margaret Chan said industrialized food production and globalized trade and distribution have given rise to chances of food contaminated with harmful, bacteria, viruses, parasites, or chemicals.

She warned that an international emergency can be caused by a local food safety problem. Jacob Kumaresan, executive director of WHO Office in New York, said the core problems of food safety are required to be dealt properly.

Governments have a very important role to play to integrate food safety in a broader food policy. Comprehensive food safety strategies need to be matched by legislation, said Kumaresan.

A multi-sector of collaboration will be a great help in ensuring that the food is produced and delivered in a safe manner. The sectors include health, agriculture, trade, environment as well as tourism.
