Resumen
El pescado constituye uno de los pilares básicos de la alimentación debido a sus propiedades
nutricionales. Los peces se encuentran íntimamente ligados a ambientes con niveles relativamente ricos
en microorganismos, y a su vez en bacterias. En este estudio, por un lado se ha analizado la carga y
diversidad bacteriana de 10 alimentos. En la segunda parte del estudio, se han testado tres antibióticos,
que han sido ampicilina, gentamicina y eritromicina en cepas bacterianas seleccionadas, para observar su
resistencia. Según nuestros resultados, los mesofilos totales se encuentran dentro de los límites
establecidos por la FAO y por el Reglamento (CE) n. º 2073/2005 de la Comisión del 15 de noviembre del
2005, a excepción de la bacaladilla que sobrepasa los niveles límites del reglamento citado en cuanto a
carga microbiana. Respecto a las resistencias a antibióticos, el porcentaje de cepas resistentes que se han
obtenido ha sido de 100%.
Seafood products play an important role in human diet due to their nutritional properties. They are closely linked to environments with relatively rich micoorganisms levels. In this research, on the one hand, bacterial load and diversity have been analyzed for 10 foods. On the other hand of the study three antibiotics have been tested: ampicilin, gentamicin and erythromycin in selected bacterial strains to analyze their resistance. According to our results, the total mesophiles are within the limits established by FAO and (CE) n. º 2073/2005 law, excluding blue whiting which exceeds the limits of the strain in its microbial load. Regarding antibiotic resistance the percentage of resistant strains that have been obtained is 100%.
