Microbial limit test

How much sample required for MLT testing ?Is this 10gm Or 20gm which are correct for MLT ?

I use 3 different batches of product to prove the consistency of the results for each microorganism’s trial. 10 grams for each batch and microorganisms would be enough. If you’re using 5 microorganisms you’ll need 50 grams of each batch of product should cover it.
