Recovery of potential pathogens from feeding bottle contents and teats in Zaria, Nigeria.
Pathogens were recovered from the contents of 41 out of 50 feeding bottles and from 32 teats in a survey in Zaria, Nigeria. 39 bottle contents and 30 teats yielded enteric pathogens. Traditional weaning gruels were more contaminated than were commercial feeds. Koko bottles yielded more pathogens than Akamu bottles. Enteropathogenic Escherichia coli was the most common pathogen recovered, seen more in bottle contents than teats. Bottle hygiene was poor and cleaning methods and feeding practices were not satisfactory. Lack of facilities in the home prevented better hygiene. Prolonged pre-cooking preparation, storage of gruels in bulk for the whole day in thermos flasks or enamel bowls, and inadequate hygiene in the preparation of commercial feeds resulted in the large recovery of pathogens. Alternate feeding methods were suggested and the need for the practice of good hygiene by all who are involved in the preparation of infant feeds was emphasized.
