Question 52

My ATP/Allergen swabs were shipped without an ice pack or were accidentally frozen. Are they still usable?

Accepted Answer

Hygiena Environmental Monitoring devices such as ATP devices, InSite®, MicroSnap®, and Q-Swab™ can tolerate 28 days at 21°C or 7 days at 37°C without significant loss of activity. However, prolonged exposure to extreme heat or freezing/thawing cycles can affect their performance. Contact Hygiena Support with the lot number and details of exposure for specific advice. It’s best to store them as recommended.

Question 53

I’m getting unexpected results (false positives/negatives) with my ATP swabs. Could sanitizers or product residues interfere?

Accepted Answer

Certain chemicals, sanitizers, or high concentrations of product residue can interfere with ATP or allergen tests. Ensure surfaces are adequately dry before testing. If you suspect sanitizer interference, test after cleaning but before sanitation. If using a one-step cleaning/sanitizing product, rinse and dry the surface prior to testing.

Question 54

Why do I get a different RLU reading when I re-measure the same device again?

Accepted Answer

You will always get a different reading when trying to re-read the same test device. The meter is reading the light given off by a bioluminescence reaction. This light peak and then begins to die off. Always measure your test device at the time recommended in the product instructions. Any result you receive after the first reading may be misleading since that light will continue to die out until eventually no light is emitted.

Question 55

How do I know the correct RLU limits (pass/fail/caution) for my application?

Accepted Answer

We do not have fixed recommendations beyond Hygiena’s default values, which are based on general industry standards. Optimal RLU limits are often site-specific and should be established through a validation process based on your facility’s cleaning standards. Contact Hygiena tech support at techsupport@hygiena.com for resources on setting RLU limits.

Question 56

Can I use UltraSnap swabs for [specific application, e.g., hands, specific bacteria]?

Accepted Answer

UltraSnap is a general ATP test for hygiene monitoring. For specific bacteria or allergens, use dedicated tests like MicroSnap, AllerSnap, or AllerTox Sticks. Consult the Hygiena website or contact your Hygiena Sales Representative for the appropriate product.

Question 57

Can I use MicroSnap™ or InSite™ tests on [specific food/beverage type] or with [specific chemical, e.g., sanitizers]?

Accepted Answer

We recommend checking the product page for AOAC validation studies and/or scrolling to the bottom of the page to access technical bulletins and validation documents, which may include matrix-specific information. Please note that we do not currently have specific interference studies for sanitizers with MicroSnap™ and InSite™. Because of this, it’s essential to validate the use of these tests in your own facility, including your specific matrices, sanitizers, and procedures, before incorporating them into your environmental monitoring program. If you need further assistance, feel free to contact us at techsupport@hygiena.com.

Question 58

My MicroSnap™/InSite™ test is giving unexpected results. What should I do?

Accepted Answer

Ensure you are following the correct procedure, including sample collection, incubation time and temperature, and interpretation. Verify the expiry date of the tests. Factors like improper storage, incorrect sample volume, or interfering substances can affect results. Contact Technical Support with details of your issue, lot numbers, and testing procedure for troubleshooting assistance.

Question 59

How long can I store InSite™ swabs after sampling but before incubation?

Accepted Answer

For optimal results, it’s best to incubate InSite™ swabs as soon as possible after sampling. If immediate incubation isn’t possible, do not snap the valve and store the swabs at 2–8 °C for a maximum hold time of 3 days.

Question 60

What type of microorganisms can MicroSnap detect?

Accepted Answer

MicroSnap Total: Total aerobic bacteria (TVC, TBC, TAC, Mesophilic count, etc.).
MicroSnap Enterobacteriaceae (EB): Enterobacteriaceae.
MicroSnap Coliform and E. coli: Coliforms and Escherichia coli. For full inclusivity/ exclusivity panel, please refer to the AOAC certificate (071302) pages 3-6.

Question 61

Is it possible to collect my sample ahead of time and run the assay later?

Accepted Answer

Yes. But only if you are testing for qualitative results (presence/absence), then it is possible to collect a sample in advance and delay the assay. To do this, collect the sample according to the instructions and put the entire inactivated enrichment device in a refrigerator (2-8 °C). When you are ready to begin the test process, remove the enrichment device from the refrigerator and activate the device according to instructions.

Question 62

What happens if I incubate for longer/shorter than indicated?

Accepted Answer

Shorter incubation time will cause your test to be invalid. Longer incubation can still be used for presence/absence testing.

Question 63

What is the swabbing solution in the enrichment device?

Accepted Answer

Butterfields buffer (Remel Phosphate Buffer).

Question 64

Do MicroSnap Coliform or E. coli detect STECs such as E. coli O157?

Accepted Answer

The enzymatic profiles for some Shiga toxin-producing E. coli (STEC), such as E. coli O157:H7, means that they will be detected and enumerated by MicroSnap Coliform testing, but not MicroSnap E. coli testing.
