No. If contamination happens they re-run the test, or call it inconclusive. They don't just randomly contaminate tests and ignore it.
IF the contamination happens (89 times out of 50K) and IF there is no more sample to test and IF the contamination is not of the actual evidence and IF the source of the contamination of the control is easily identified (in this case the lab tech doing the test) - THEN they can apply for a deviation from protocol.
All those conditions rarely happen but these are human beings doing the testing, and the tests are exceedingly sensitive, so yes it can happen. They are not infallible.
LOL at saying you can't trust any of the DNA results from this lab because contamination happened some tiny percentage of the time, just ridiculous. You may as well say courts can no longer use DNA evidence - the contamination happens in every lab some small percentage of the time.
