Goats milk was examined for total viable bacteria and staphylococci (Baird‐Parker medium, Schleifer & Kramer's (SK) medium, SK medium with a reduced sodium azide content (SKR) and SK and SKR with 5% added sheep blood). Staphylococcus aureus, Staph. epidermidis and Staph. simulans were the predominant species isolated overall. SK medium proved inhibitory with respect to the isolation of Staph. caprae and Staph. chromogenes. This was reduced by plating on the modified SK media. Representative strains of each species isolated were examined for production of enterotoxins A‐E. Enterotoxin C alone was produced by 35% of the Staph. aureus strains tested. None of the other staphylococcal species examined produced any of the known enterotoxins.
