Cows will shit in the milking shed with the same frequency as they will shit anywhere else they stand. Probably a higher freqency because they are often agitated by the loud noises, and hairless apes fondling them.
The machines used to milk them are very simple pneumatic massagers hooked up to a vacuum hose. If those machines fall off, or get kicked off by an agitated cow, they will suck up whatever else they come in contact with until someone notices and comes to pick them up again or shut them off.
It is an absolutely regular occurence that cow shit gets sucked up into the lines and pumped into the milk vat. Filter socks(think a coffee filter, but the size of a poster-tube) are installed in the line before the milk vat to reduce the amount of solids that make it through, but there is always some amount of liquefied cow shit ending up in the milk.
A not-insignificant amount.
