Compact Dry X-SA plates let quality teams verify Staphylococcus aureus levels—a critical check of personnel hygiene and sanitation. Each pre-sterilized dish contains selective agents and a chromogenic substrate. Target colonies develop as light-blue to blue circles, while background flora are suppressed for clear, accurate counts.

Compact Dry X-SA streamlines S. aureus monitoring, delivering clear, next-day results that keep hygiene programs on track and products safe.

Key Benefits

AOAC Performance Tested Method – validated for regulatory confidence.
True “open → inoculate → incubate” workflow – no agar prep, spreading, or autoclaving.
Distinct chromogenic read-out – blue colonies stand out against a pale background, making enumeration fast and photo-documentation effortless.
Hygiene sentinel – ideal for detecting post-process contamination in dairy, meat, confectionery, ready-to-eat meals, and environmental swabs.
Ambient-stable & stackable – store at 1 – 30 °C; slim plates fit densely in incubators to maximise capacity.
Supports HACCP & personnel monitoring – high counts flag inadequate hand-washing, glove changes, or cleaning procedures.
