TYMC

Total combined yeasts and moulds count, determined on Sabouraud Dextrose Agar at 20–25 °C for 5–7 days, as described in USP <61>. Any bacteria that grow on SDA are included in the count, and SDA with antibiotics may be used if justified. TYMC is reported as CFU per gram or mL and compared with the acceptance criterion, for example 10² CFU/g for non-aqueous oral products, allowing a maximum of 200.
