The role of food safety in child survival programmes
Editor The article by F.F. Fikree et al. (1) reports that diseases of infectious etiology (diarrhoea and ARI) were the leading clinical causes of death in the post-neonatal period with diarrhoea being responsible for 43.3% of all deaths. The authors conclude that child survival programmes must therefore maintain and strengthen their strategies for prevention and control of these infections. As far as diarrhoea is concerned, the wide use of oral rehydration salts will certainly be successful in helping to reduce mortality. However, in order to reduce morbidity, the causes of infant diarrhoea need to be elucidated.
Despite the fact that three successful prevention strategies (i.e. breastfeeding, immunization, drinking-water and sanitation) have been strongly promoted in the past, surveys of diarrhoeal diseases indicate that these interventions have not been fully effective in preventing diarrhoeal diseases in infants and young children (2, 3). On the other hand, there is strong evidence that food and poor food handling practices play a major role in the transmission of diarrhoea. Is it perhaps possible that the child survival programmes are incomplete, and need to be complemented by measures to assure the safety of the complementary food (weaning food) given to the infants? After all, diarrhoea is caused by pathogens that need to enter the child's body through the mouth. Since complementary food contains substances that are not only nutritious for the child but support the growth of bacterial pathogens, regarding food as a vehicle of transmission of pathogens appears to be logical. In 1993, the Bulletin published an article that suggested contaminated food was a major cause of diarrhoea and associated malnutrition among infants and children (4). The role of food in the epidemiology of diarrhoea had also been recognized by the 1992 Joint FAO/WHO International Conference on Nutrition (5).
The results published by Fikree suggest that this link ought to be considered and the prevention strategies appropriately amended to include food safety. In 1996 WHO issued Basic Principles (6) for the safety of complementary food. What is needed is their vigorous implementation.
