3M MDA 2 Listeria species and L. monocytogenes Collaborative Study OMA-2016-MONTH-XXX

4.1.10 Raw chicken fillet (25 g): 28-32 hours of enrichment in Demi Fraser broth at 37°C 4.1.11 Stainless steel : sponge in 225 mL with 24-30 hours of enrichment in Demi Fraser broth at 37°C 4.1.12 Concrete : sponge in 100 mL and 225 mL and sponge in 225 mL with24- 30 hours of enrichment in Demi Fraser broth at 37°C 4.1.13 Plastic : Enviroswab in 10 mL 24-30 hours of enrichment in Demi Fraser broth at 37°C Caution : The 3M MDA2 - Listeria is intended for use in a laboratory environment by professionals trained in laboratory techniques. The user should read, understand and follow all safety information in the instructions for the 3M MDS and the 3M MDA2 - Listeria and retain the safety instructions for future reference. The 3M MDA 2 - Listeria method may generate Listeria monocytogenes to levels sufficient to cause stillbirths and fatalities in pregnant women and the immuno compromised, if exposed. The user must train its personnel in current proper testing techniques: for example, Good Laboratory Practices, ISO 17025, or ISO 7218. Follow all instructions carefully. Failure to do so may lead to inaccurate results. The 3M Molecular Detection Instrument is intended for use with samples that have undergone heat treatment during the assay lysis step, which is designed to destroy organisms present in the sample. Samples that have not been properly heat treated during the assay lysis step may be considered a potential biohazard and should NOT be inserted into the 3M MDS (instrument). Store the 3M MDA2 - Listeria at 2-8°C. Do not freeze. Keep kit away from light during storage. After opening the kit, check that the foil pouch is undamaged. If the pouch is damaged, do not use. After opening, unused reagent tubes should always be stored in the resealable pouch with the desiccant inside to maintain stability of the lyophilized reagents. Store resealed pouches at 2-8°C for no longer than 1 month. Do not use 3M MDA2 - Listeria past the expiration date. Expiration date and lot number are noted on the outside label of the box. After use, the enrichment medium and the 3M MDA2 - Listeria tubes can potentially contain pathogenic materials. When testing is complete, follow current industry standards for the disposal of contaminated waste. Consult the local regulations for disposal. 4.2 Test Kit Reagents - 3M MDA 2 - Listeria - 96 tests
