[Presence of total coliforms, Escherichia coli and Listeria sp. in enteral formulas].
Archivos latinoamericanos de nutricion, 1999 The presence of total coliforms, Escherichia coli and Listeria sp. was evaluated in 65 samples of enteral nutrition formulas. In more than the 75% of the samples made up from cooked vegetables, fruits or meat broth, the score level of total coliforms was of 10(4) UFC/g. In 12-31% of the different enteral food formula, E.
