Resumo
In Santos, coast of São Paulo State, the evaluation of the microbiological
quality of the beach water is performed weekly by the Companhia
Ambiental do Estado de São Paulo (CETESB), the environmental agency of
the São Paulo state government. However, the same attention is not given to
the sand of the beaches. Sand represents a potential contamination vector
and may constitute a reservoir of pathogenic microorganisms. This study
aimed to evaluate the microbiological quality of sands from Santos beaches
throughout the quantification of bacteria colonies from the groups of fecal
coliforms (Escherichia coli) and Enterococcus, using the membrane filter
technique. The analyses were executed monthly during 8 months and the
results, expressed in bacteria colony forming units (CFU) per 100 grams
of sand, vary from 40,000 to 2,700,000 for E. coli and from not detected
to 95,000 for Enterococcus, being above the currently guideline values in
national (3,800 CFU.100g-1) and international (100,000 CFU.100g-1) levels. It’s
important to mention that these guideline values were based on results from
microbiological analyses of sands collected from beaches that are distant from
large urban areas. The contact with contaminated sand may cause diseases,
provoking impacts on the population’s life quality. There is a need for further
studies based on epidemiological evidences of exposure and risk analysis, in
order to establish quality standards and public policies aimed to monitoring
and managing the sanitary quality of sands from São Paulo’s coast beaches.
