SUMMARY The bacteriology of 20 paired samples of breast milk was analysed to find out if discarding the first few millilitres would reduce the amount of bacterial contamination in breast milk donated to a hospital milk bank. The first sample was the initial 2-3 ml collected from the opposite breast to that first suckled by the baby, and the second was a midstream sample from the same breast. There was no significant difference in the colony counts between the paired samples, and in no instance did the bacterial flora of the second sample differ from that of the first.
Corn tortillas are a common food in the diet of people of Mexican descent who live in the Los Angeles area. Corn tortillas are not enriched, and on a weight basis contain less iron, thiamin, riboflavin, and niacin than enriched white bread. The mean intake of iron, thiamin, and riboflavin is below two-thirds of the RDA for an important segment of the population consuming this product. The addition of these nutrients to corn tortillas made in Los Angeles would be an effective means of increasing iron and vitamin intake.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
