Most research now says it’s transmitted almost exclusively thru the air, breathing it in & surface transmission is very unlikely. At the beginning of the COVID crisis, no one was sure by what routes it caused infection, so just to be safe they recommended sanitizing surfaces & frequent hand-washing, but they’re not saying that now.
The article I read quoted the health authority who said, it was hard to know for sure where a lot of the 52 got it because many people were so careless that they had multiple potential sources of infections from the many infected similarly careless residents - which ties in with the resident's comment indicating when getting tested they couldn't even be bothered with caution while standing near others who were likely infected.
The research is beginning to come around to a tentative conclusion that people most likely get Covid-19 by transmission through the air. It sounds like you're likely OK, except that you shouldn't be eating with hands that aren't clean for other reasons besides Covid-19. :)
No one knows how easy it is to get from touching because it is invisible and hard to know how much viral load is needed to infect someone. Everyone has been infected accidentally so no scientist is able to know the viral load that hit the infected person's airway to create transmission. You don't know that the "germs" weren't old and all dead anyway, or that a Covid person coughed on the surface you touched either, so there are too many unknowns for you to know if you even had a risk. The only thing for you to do is check for symptoms and sd from others for a few weeks, which is what you sb doing anyway.
