hető. Ha azonban az atkás takarmány a megengedettnél nagyobb mennyiségben tartalmaz baktériumokat és gombákat, közvetlenül az etetés előtt csirátlanitani kell. Large quantities of meal-mites Acarus siro and Tyrophagus putrescentiae isolated from mite cultures were fed to poultry

, guinea pigs,rabbits and sheep for 6-21 days, without causing any adverse effect.As in this way it was proved that disease conditions reported in foreign literature as a consequence of feeding mite invaded food are not caused by the mites themselves, the invaded food was further investigated. Bactériologie investigations proved that food samples invaded heavily with meal-mites have a total germ count exceeding several times tolerable levels. As the growth of bacteria and moulds is promoted by the same environmental factors (humidity, high temperature) advantageous also for the mites, food samples invaded with mites should be tested bacteriologically before use. In case of advantageous bacteriological results the food containing meal-mites can be used without risk for the animal species used in this experiment. However, if the food

'contains bacteria and moulds in numbers exceeding fixed levels, it has to be sterilized immediately before use. Autoref
