Safari 5.1.7 randomly zooms on my mid 2011 27 inch iMac and will not return to normal until I quit theapplication.
From your Safari menu bar top of your screen, click Safari > Preferences then select the Extensions tab.
If you have any extensions installed, turn that OFF, quit then relaunch Safari to test.
And check System Preferences > Universal Access > Zoom
Make sure it's off.
