In third tested sample, day, species found, 41.6 With weak intensity microflora 31 CFU/cm3, products, namely parts liver, sent disposal, non-affected carcass subjected heat treatment released sale without restrictions. Following current normative documents DSTU 4831:2006, 7444:2013, ISO 6888-1:2003, high infestation, as well including detection more than 30 such product considered fresh subject disposal.
