Is my garden more safe from harmful pathogens?

I am not sure if this is the right place to ask but… I just heard about outs breaks of e coli and salmonella ECT. Because America has pretty bad food safety. But it seems like most outbreaks come from either cow poop run off on the farms or rat poop in the packaging facility. So my garden which does not have poop ( specifically not composted poop) should be much safer right? Also I will still wash my food and stuff obviously.
