While I'm talking about it, probability is very important. There is, of course, the potential for high levels of infestation or very low-level prevalence. What we seek to do is, of course, detect. However, it is important to understand that detecting a low-probability event will be difficult to replicate. This committee is very familiar with low-probability events, such as in the case of BSE and the challenges that individual positives present in that regard. It doesn't mean those positives aren't real, but it is a very low-probability event that's being responded to.
