Hygiena SpotCheck Plus is a rapid swab test that detects glucose and lactose residue on surfaces as a quick indicator of surface hygiene. These sugars are common in food residue, so finding them after cleaning means the surface wasn't cleaned properly. Swab the surface, snap to release the reagent, and read the colour after 60 seconds. If it stays clear, the surface passes. If it turns green, it's not clean.
SpotCheck Plus needs no instrument and no incubator, so anyone on the sanitation team can use it at the line. It's sold in boxes of 100 single-use tests. Hygiena SpotCheck Plus is available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
Read the result after 1 minute and re-clean straight away if the surface fails. Staff don't have to wait for lab results before starting production.
The colour change is read by eye against the chart on the tube label. There's no luminometer, reader or incubator to buy, calibrate or maintain.
Hygiena states SpotCheck Plus detects down to 2.5 µM D-glucose and 5.0 µM lactose within 1 minute. The more sugar present, the faster and darker the colour change.
The swab and reagent are in one self-contained device, with no pipetting or mixing. Hygiena describes the devices as 100% recyclable.
| Colour | Result | Action |
|---|---|---|
| Clear | Pass | Surface is clean. No action needed. |
| Light green | Caution | Small amount of residue. Re-clean, rinse or re-test according to your protocol. |
| Dark green | Fail | Not clean. Re-clean and re-test. |
Steps and interpretation are from the Hygiena SpotCheck Plus instructions for use. Hygiena recommends running positive and negative controls as part of good laboratory practice.

Glucose and lactose residue on surfaces. These sugars are common in food residue, so detecting them shows a surface hasn't been cleaned properly.
1 minute. If there's no colour change after 2 minutes, the test is negative.
No. The result is read by eye against the chart on the tube label, at room temperature.
Clear means pass, light green means caution, and dark green means fail.
Yes. Lactose is the main sugar in milk, so the test is a direct check for milk residue on dairy equipment.
Refrigerate at 2–8 °C and don't freeze. Devices can be kept at 9–22 °C for up to 4 weeks. Let them reach room temperature before use.
Yes. Cambridge Environmental Products supplies Hygiena SpotCheck Plus across Canada with CAD pricing.
