I’m surprised whenever an outbreak of foodborne illness is picked up in the U.S., except the most egregious violations of sanitation and safety, where large numbers of people are sickened.
Those investigations with people scattered across states, like the current E. coli O145 outbreak that has sickened over 50, are a testament to the skill, dedication of training of public and environmental health types.
Yet across the U.S., public health is taking budgetary hits as the trickle down of housing and financial collapse makes its way to the local level -- states and counties are looking everywhere to balance the books.
