SS-L04

Description:

A direct chromogenic test for the presumptive detection of faecal indicator organism E. coli and Lactose positive Coliforms from food contact/preparation areas or manufacturing environments where regular disinfecting/sanitising is performed. Results are easily visualised using the inbuilt colour change system giving clear results. Kit includes Pre-moistened (in TSC Neutralising Buffer) 45mm Breakpoint Swab for simple sample transfer. ISO18593:2018 compliant when used a template - see TS/15-T40

The presence of E. coli in SS-L04 media is Turquoise/green (alone) to blue-purple (with coliforms). Coliforms alone are pink/mauve. Formulation inhibits/suppresses other background microorganisms such as Staphylococci, Bacillus spp., Enterococcus spp., Micrococcus spp. and E. coli confirmation is possible with 2-3drops of Kovacs or Ehrlich Reagent within the tube completing the test (see IFU for details). Neutralising Swabs are included in the kit but also sold separately – see TS/6-61BP250.

Recommended For: food contact, equipment or environmental surfaces sampling only.

Ideal For: Detecting E. coli and Coliforms from food preparation areas, associated equipment or the environment. Routine Sampling for Pathogens is a fundamental part of Good Manufacturing Practice (GMP)and essential for adhering to a HACCP (Hazard Analysis Critical Control Points) plan. This product can be used to complement (or in conjunction with) the ISO 16649-3 testing/detection methodology.

Known Limitations:
1. SwabSURE is intended as a screening test. Positive results should be confirmed by standard bacteriological or molecular methods. 

2. It is recommended that after sampling food contact areas are wiped to remove any residual traces of neutralising solution. If used for direct food contact the item must be removed/discarded after use (so not sold).

3. Has not been validated for uncleaned food surfaces. The use of SwabSURE for these purposes may result in false positives or spurious/unreadable results.

4. The absence of a colour change does not necessarily imply the absence of target bacteria. Reasons for this may include:

a. Inadequate neutralisation of sanitising agents.

b. Numbers of target organisms are below the detection level of the test.

c. The target organisms, although present may be severely damaged and unable to be resuscitated.

5. The organism Shigella spp. can colour like E. coli, but is quickly distinguished using Kovac/Ehrlich as indole negative (so no red ring produced), see infosheet. However, presence of Shigella spp. should still considered significant and be investigated/evaluated to find contamination source.

Shelf Life: 12 months - Components should not be used after the expiry date printed on them or the carton label.

Storage: Store at 2-8°C when not in use. The pre-moistened swabs should be stored at 4-25°C.

Sterilisation Method: Terminally Sterilised (detection media autoclaved, swab gamma irradiated)
