摘要:The worth of infant feeding is for not only growth and development in infancy but also for the long term health well into adulthood of the supreme significance. The use of pediatric infant formula (PIF) is widespread to provide nutrition for infant. Pediatric infant formula is not a sterile product and opportunistic pathogens could multiply in the reconstituted product, resulting in infections. During the manufacturing of PIF, the chances of the contamination of microbial growth has been increased many folds. In recent years, the microbes which are of mainly concern related to the contamination in PIF were Cronobacter sakazakii, Salmonella species, and Bacillus cereus. The present project has been designed to evaluat e microbial contamination of twenty six selected brands of pediatric infant formula marketed i n Karachi, Pakistan. It has been affirmed by the result that two sampl es were contaminated by Gram-negative Cronobacter sakazakii and one of sample was cont aminated by Gram-positive Bacillus cereus. These potential pediatric infant formula-borne pathogens were within the range of Codex Alimentarius Commission. Moreover, two PIFs have probiotics which were Gram-positive Lactobacillus and Bifidobacterium species mainly aid in the digestion, stimulate the immune system, and inhibit the growth of pathogens, effective against bacterial induced gastroenteritis, and even recovery from acute diarrhea in children
