Provided are methods and devices used for determining the presence or absence of a contaminant in the sample of oral fluid. The method involves contacting a substrate having a detectable reporter with a sample of oral fluid and, based on determining a signal from the detectable reporter determining the presence or absence of a contaminant in the sample of oral fluid. The invention is useful for detecting lactose, milk, colostrum, blood, hemoglobin, whole cells, and combinations thereof. The method can be used for detecting oral contaminants in oral fluid samples obtained from any mammal, including neonatal ungulates.
