You can wash it off a steak or chicken. That crunchy stuck in your teeth from a hot dog or sausage just might be a rat turd. I'm not a germ freak, I just don't like the taste.
Again, you seem not to understand the numbers and realities of measurement. The standard is far below anything you might encounter as "crunchy." Something large enough to be "crunchy" or noticeable at all in your mouth would be larger than the standard.
This type of ignorance is a shame.
