<br><br>This is actually a common fallacy that most people believe but is not true. Although the pasuk says "umazeh mei hanida yechabes begadav" seemingly saying that the Kohen who sprinkles becomes Tamei, Rashi there quotes the Gemara in Nidda that the Kohen who is Mazeh is actually tahor and only the nosey (the one who carries it) becomes tamei. In other words, the Kohen who performs the Tahara process on the person who is tamei does NOT himself become tamei.
