title: Intra-laboratory validation of the Ridascreen® SET Total kit for detecting staphylococcal enterotoxins SEA to SEE in cheese.
abstract: OBJECTIVE
  To determine the performance of the Ridascreen® SET Total kit, after sample extraction and concentration by dialysis, with regard to its use in official controls for staphylococcal enterotoxins under European Regulation (EC) No. 2073/2005 modified. This study was conducted on naturally contaminated cheese samples and compared with the results of the previously validated Vidas® SET2 kit.
  
  
  RESULTS
  The effectiveness of the Ridascreen® SET Total kit on naturally contaminated cheeses was compared to that of the Vidas® SET2 kit by applying the EN ISO 16140 standard. Sensitivity and specificity were also compared using spiked buffer solutions and cheese samples with SEA to SEE toxins.
  
  
  CONCLUSIONS
  This study showed that the Ridascreen® SET Total kit is as effective as the Vidas® SET2 kit.
  
  
  CONCLUSIONS
  The Ridascreen® SET Total kit was found to specifically detect SEA to SEE in cheeses. The Ridascreen® SET Total can therefore be used to check the staphylococcal enterotoxin content and ensure consumer protection.
