Microbial limit test (MLT)
Tests for the number of micro-organisms, TAMC and TYMC, and for the absence of specified organisms such as E. coli, Salmonella, P. aeruginosa and S. aureus in non-sterile products. MLT follows USP <61> and <62>, with acceptance criteria by dosage form from USP <1111>. It is performed on raw materials, intermediates and finished products such as tablets, syrups and creams, after method suitability has been shown for each product.
