Fish contamination by sewer threatens food safety

By Diego L. S. Navia and Daniel Vidal Pérez |

A study conducted in Myanmar Archipelago, focusing on the marine enviroment and fish, found about 67 pathogenic agents that may cause an emergency on public health, 78 distinct types of material contaminants and 60 kinds of toxic sediments. Waste derived from coastal urbanization deeply impacts food safety. Seafood is still one of the most negotiated commodites around the world, surpassing the combined value of the sugar, corn, coffe, rice and cocoa trade. The overall supply of seafood for human consumption has exceeded the population growth, increasing annually on a average rate of 3,2%. 

Impacts on Defense and Security: According to the World Health Organization (WHO), diseases associated to both food and water contamination has lead to 1,38 million deaths per year. Given the importance of the seafood comercialized as a global protein source, it is essential to develop strategies to safeguard the consumption this type food, and consequently to ensure public health.
