Implication

In vitro study demonstrates enterotoxin production despite predominant non-enterotoxigenic staphylococci in milk and ham, highlighting challenges in diagnosing food poisoning outbreaks.

Key Points

To evaluate staphylococcal enterotoxin production when enterotoxigenic Staphylococcus aureus strains are co-cultured with non-enterotoxigenic strains in food products.
Co-cultured enterotoxigenic and non-enterotoxigenic Staphylococcus aureus strains in laboratory growth medium, milk, and ham.
Differentiated enterotoxigenic strains from non-enterotoxigenic strains using differential colony pigmentation.
Enterotoxin was detectable in milk when non-enterotoxigenic strains outnumbered enterotoxigenic strains by 15:1 to 20:1, with enterotoxigenic counts reaching 10^7 colony-forming units per ml.
Enterotoxin was detectable in ham when the ratio of non-enterotoxigenic to enterotoxigenic strains reached 60:1 to 77:1, corresponding to 10^8 colony-forming units per ml of enterotoxigenic cells.
Diagnostic detection in food poisoning investigations may require screening up to 50 or 60 isolates to identify the enterotoxigenic population.
