Microbial checking courses for managed environments really should assess the usefulness of cleansing and sanitization techniques by and of staff that can have an impact around the bioburden of your controlled setting.

Microbiological sampling has the possible to contribute to microbial contamination due to inappropriate sampling strategies. A formal personnel education method is necessary to attenuate this danger. This formal training must be documented for all personnel getting into controlled environments.

Pada saat penimbangan bahan diharapkan tepat sesuai kebutuhan tidak boleh kurang, dikarenakan pada saat penimbangan misalkan bobotnya sedikit dibawah kebutuhan akibat kelalaian personil maupun karena personil tidak mengetahui nilai koreksi timbangan media tersebut konsentrasinya dibawah yang dipersyaratkan dan akan berpengaruh terhadap nilai nutrisi media untuk pertumbuhan mikro organisme.
