Food products are generally well controlled and manufactured to a consistency where microbial specifications are established. S80 3JJ, About Us The normal expected variation from plate counts is typically 0.2 to 0.5 Log units, so for a target 1,000 CFU (Log 3.0), an actual result can be anywhere between 300 to 3,000 CFU and still be considered microbiologically equivalent. The unit of measurement for the enumeration of microbes is a colony forming unit (CFU) derived from plate count methods. Such variation is well known and regularly examined among accredited testing laboratories. Looking at my recent lab results for sliced yellow onions I see Total staph-ND, S aureus-ND, Kassy, Your email address will not be published. By reporting <1cfu/g, the lab are saying that there is an inaccuracy of 1 in that test, but essentially that the result was 0, because they couldn’t find anything on the plate. No we not manufacture this product Into the Lab.awe are s manufacturer of this product and all is done through the HACCP and is been validated. How to Interpret Microbiology Results - Bacteriology There are methods to systematically read chest X-rays and a similar approach should be taken to laboratory results. 2. However, as you can see from the table below the pre-examination / pre-analytical phase also plays a part in the cause of spurious results produced by the laboratory. The interviewees describe the processing of specimens in three steps: pre-analytical, analytical and post-analytical.
