Abstract

Pepitona or turkey wing, Arca zebra check for this species in other resources (Mollusca: Bivalvia: Arcidae), is a product of massive consumption in eastern Venezuela. Monthly samples (march to september 2004) of pepitona meat were taken from vending places in the Cumana Municipal Market, in order to determine their hygienic conditions. Plate cultures of Staphylococcus aureus check for this species in other resources and enterobacteriae, and detection of Vibrio check for this species in other resources spp. were made. The identification was made using differential biochemical tests based upon the metabolic activity of each isolated strain. The analyses showed a high degree of contamination by S. aureus and enterobacteria in samples of pepitona meat, with average values 1.8 x 102 to 6.4 x 103, and 2.5 x 102 to 5.4 x 103 CFU/g, respectively. A total number of 61 strains of S. aureus were isolated, of which 39.1% yielded positive to the coagulase test and 41.7% to the DNAse test. Ten species of the family Enterobacteriaceae were identified, being Escherichia coli check for this species in other resources the most predominant with 25% prevalence. The following Vibrio species were identified: V. alginolyticus, V. parahaemolyticus, V. metchinikovii, V. fluvialis and V. mimicus. The presence of pathogens in pepitona meat freely sold to the public in the Municipal Market of Cumaná was demonstrated.

Resumen

La pepitona, Arca zebra check for this species in other resources , (Mollusca: Bivalvia: Arcidae) es un producto de consumo masivo en el oriente de Venezuela. Se recolectaron mensualmente (marzo a septiembre 2004), muestras de pepitonas provenientes de expendios del Mercado Municipal de Cumaná, con el fin de determinar su condición higiénico-sanitaria. Se efectuaron recuentos en placa de Staphylococcus aureus check for this species in other resources , enterobacterias y detección de Vibrio check for this species in other resources spp. La identificación se realizó utilizando pruebas bioquímicas diferenciales basadas en la actividad metabólica de cada cepa aislada. Los análisis revelaron contaminación por S. aureus y enterobacterias en las muestras de carne de pepitonas, con valores promedio de 1,8 x 102 a 6,4 x 103 y 2,5 x 102 a 5,4 x 103UFC/g, respectivamente. Se aislaron 61 cepas de S. aureus, de las cuales 37,7% resultaron ser positivas a la prueba de coagulasa y 42,6% a la DNAsa. Se identificaron diez especies pertenecientes a la familia Enterobacteriaceae, siendo la predominante Escherichia coli check for this species in other resources con 25% de prevalencia. También fueron identificadas las siguientes especies de VibrioV. alginolyticus, V. parahaemolyticus, V. metchinikovii, V. fluvialis y V. mimicus. Se demostró la presencia de patógenos en carne de pepitona libremente expendida en el Mercado Municipal de Cumaná.
