Scaring people with chemistry is easy to do, in this case by people who likely don't understand the first thing about the field. 
If you compare ethylene oxide (ethene oxide) with other chemicals in our environment, like ammonia and formaldehyde, it isn't as bad. I will show you this. 
The other question would be how much of the gas is left on testing swabs after packaging. That I cannot answer, although I'm not worried.
