PDA中写的不需要?
哪份报告 ,第几页 第几行?
PDA写的是不做回收率。
PDA TR29的6.5.5章节中,
Recovery studies to determine percentage recovery from surfaces are not appropriate and are not normallydone for microbiological sampling. One reason for this is the question of enumeration in
microbiologicaltests – “colony forming units” are typically counted as opposed to individual organisms.A second reason for this is that vegetative organisms will die or lose viability when dried on a couponin a standard sampling recovery procedure. A third reason is that it is unclear which species should beused for a recovery study. A fourth reason is that typically the limits set for bioburden are significantlybelow what could possibly cause either product quality issues orprocess performance (e.g., SIP) issues;therefore, even though recovery may be low (<50%), product quality and/or process performanceis not impacted by not including a recovery factor.
佩服PDA!还能扯出来1234,真厉害!
在看PDATR29之前,我也有一个论调,我只有一句话:微生物擦拭回收率做不准,就算做准了也没屁用!后来看了这段PDA,发现跟我的意思没啥本质区别,无非是比我字多。 |
