Sponge swab and Stomacher technique proved to be highly effective sampling combination for assessing large surface areas
Seward Ltd., manufacturers of the world leading range of Stomacher® paddle blenders and Stomacher® accessories used in sample preparation for microbiological analyses, have highlighted the highly effective use of its Stomacher technology in combination with sponge swabs for hygiene monitoring and biosecurity applications.
The Seward Stomacher® 400 Circulator
Hygiene monitoring in food and pharmaceutical production facilities and clinical environments requires simple sampling techniques with excellent microbial recovery rates across a spectrum of different species. A recent study has confirmed the effectiveness of the combined sponge swab and Stomacher sampling methodology for sampling a large surface area.
This popular sampling method utilises sponge swabs pre-dosed with buffer to swab a surface and then, to recover the micro flora, the sponge swabs are processed in the Stomacher® 400 Circulator. A number of suppliers offer pre-manufactured devices such as 3M® and Technical Services Consultants Ltd, which work very effectively in Stomacher products. Various different approaches can be applied, processing either pooled samples in the Stomacher® 400 or individual swabs in the Stomacher® 80 Biomaster.
