Eggs and Salmonella

The most recent outbreak of Salmonella in eggs doesn't worry me considering I have switched to buying eggs from a local farmer.  But it does scare me and is just another reason on the list of why factory farms are awful.  I keep wondering with all the different outbreaks of issues in spinach, peanut butter, eggs, meat, etc. why practices haven't drastically changed.  We will continue to support local, humane farmers who follow respectable practices.  Hopefully the rest of the world will join the bandwagon.
