Abstract
The study described in this article evaluated sources of contamination of
children’s food and drinking water in rural households in the highlands of Peru. Samples
from children’s meals, drinking water, kitchen utensils, and caregivers’ and children’s
hands were analyzed for total coliforms and
E. coli
counts using Petrifilm EC.
Thermotolerant coliforms in water were measured using DelAgua test kits while
diarrheagenic
E. coli
were identified using polymerase chain reaction methods (PCR).
Thermotolerant coliforms were found in 48% of all water samples.
E. coli
was found on
23% of hands, 16% of utensils, and 4% of meals. Kitchen cloths were the item most
frequently contaminated with total coliforms (89%) and
E. coli
(42%). Diarrheagenic
E.
coli
was found in 33% of drinking water, 27% of meals, and on 23% of kitchen utensils.
These findings indicate a need to develop hygiene interventions that focus on specific
kitchen utensils and hand washing practices, to reduce the contamination of food, water,
and the kitchen environment in these rural settings.

Abstract
In order to assess the prevalence of nonzoonotic soil-transmitted helminths
in the Yenagoa Metropolis, 480 soil samples were collected from five communities
for 12 months. The soil samples were collected along two transects from the
waterfront and community playgrounds. Analysis was by standard methods. The
results obtained from the study described in this article showed that 44.79% (95%
