Although psicrotrophic bacteria are not thought as health risk indicators, the presence of this group of microorganisms has been investigated in ice-creamm as they are important in determining the quality of frozen food.
Forty four (44) samples of ice cream have been analyzed. Most of them (40 samples) came from bulk containers, that were open and manipulated during selling.
The results showed that 37 out of 40 samples were contaminated, with different number of countings. Several different species have been isolated, being Enterobacter and Pseudomonas the more frequent. Another microorganisms considered psicrotrophic such as Klebsiella, Flavobacterium, Chromobacterium, Acinetobacter, Aeromona, Moraxella, Alcaligenes and Serratia, have been also encountered.
