The aims of this study were to study the occurrence of S. aureus in bulk tank milk samples and to test their potential to produce staphylococcal enterotoxins (SEs). A total of 511 bulk tank milk samples were collected from 305 farms in 9 different regions of the Czech Republic. S. aureus was detected in 199 (38.9%) samples. The S. aureus positivity rates varied with sample origin (farm) and ranged from 0 to 67%. The potential to produce enterotoxins A–J was confirmed in 89 (44.7%) of 199 S. aureus isolates. The most commonly detected genes were seg (35.2%) and sei (31.7%). Both genes were detected in 23% of the isolates. Other genes detected were seb (in 5.0% of enterotoxin-positive isolates), seh (5.0%), sed (4.0%), sec (2.5%) and sej (0.5%). The variation in the rates of toxigenic isolates can be attributed primarily to the colonization of farms by specific clones of S. aureus.
