I ate a potato from a hot cholent. Would it be muttar for me to eat a piece of bread which has gone through a conveyor toaster which has been used with bread and cheese and there are still remnants of cheese on the conveyor?
It is permitted to eat the bread even though it was on a milky conveyor as long as there isn’t any cheese on the bread itself. If there is cheese on the bread itself then you are eating cheese within 6 hours of eating meat. If however there is no meat on the bread and it was only heated in a dairy oven then it may be eaten.
