Studies on the Microbiology of Fresh Goats' Milk

Abstract

A microbiological investigation for hygiene and types of contamination of fresh goats' milk was conducted. The results indicated very high viable bacterial count. The bacteria isolated and identified were coliform bacteria, Staphylococcus aureus, Streptococcus faecalis, S. bovis, S. thermophilus, Streptococcus group E, Lactobacillus casei, L. bulgaricus, Bacillus sp., but Salmonella sp. and Shigella sp. were not detected. Yeast's species isolated were Saccharomyces exeguus, Klnyveromyces marxiemes and Brettanomyces sp. Different types of moulds were present. The results are discussed according to the standards of milk and the importance of lactic acid bacteria and yeast isolated.
