a. Dilakukan setiap bets media siap pakai dan setiap bets media baru yang dibuat. Biasanya pada pengujian mikrobiologi dalam membuat media uji disiapkan media untuk beberapa kali pengujian beberapa hari ke depan, pembuatan media tersebut adalah satu bets media dan perlu dilakukan uji
Begitu juga sebalikanya apabila dari media yang ditanam bakteri yang jumlahnya misalkan 75 cfu dan ternyata here jumlah bakteri yang tumbuh lebih dari 50% dari jumlah bakteri yang ditanam dapat disimpulkan bahwa pengujian jumlah bakteri dan jamur pada sampel produk sudah legitimate.
