Augmented use of irradiation technology, used in conjunction with other handling and processing safeguards, would go a long way to preventing future contamination of our food by E. coli, salmonella, and listeria bacteria.
Here's a really strange solution: stop feeding cattle grains as feed suppliments:
http://www.sciencedaily.com/releases/2008/01/080122102428.htm Although the article cites 'used distillation grain' as a source of E-coli contamination in cattle, it has been known by veternarians for sometime that any grain or grain-byproduct can increase the likelihood and severity of E-coli infections in cattle. Eliminating the grain and letting cattle feed on grasses instead tends to reduce and efficitively eliminate the threat of E-coli contamination from feed. No irradiation needed...
By reducing cattle bourn E-coli, we can efficively reduce the incidents of contamination of other human food sources such as greens (lettuce, etc.) which are typically grown in fields either adjacent to or within 10 kilometers of cattle fields (flies landing on cow patties can spread E-coli by subsequently landing on lettuce and other greens in nearby fields...) This is a totaly disgusting but completely natural and uncontrollable side effect of nature!
But in all honesty, E-coli can be effecitively controlled if silly humans would only wash their produce thoroughly before eating, and cooking their beef patties so that they are completely done through and through...
The first step in avoiding contamination is simply assuming that it is always there...then apply appropriate and fairly simple cross contamination rules to safe gaurd your family. Common sense really!

Obviously you have direct experience in the food prep and distribution of food.
I was a corpsman in the USN on ship long ago (ship had no desalination plant). As one of my duties I was responsible with monitoring, conditioning, purity and sanitation of water coming abroad our ship's water tanks. Without any safeguards in potable water onboard it's obvious what could happen to a ship's crew.
I also tend to subscribe the Earl Butz supply idea: quality, safe, 'plenty of cheap' food to the grocer.
As a ranch hand I have noticed the arguments with cattle raising and safe meat production.
I look at food as maintaining quality safe food and above all insuring the price of food is plentiful and affordable for all.
I also look at the public health issue of food production on insuring standards that are bullet proof. The public must have absolute confidence for example, deli meats are safe for all including elderly and infant sectors of the population.
It's unrealistic to expect adherence to suggested absolute safe agriculture practises 24/7 or the reasoning of 'free ranging' grass fed cattle. Depending on location this is practical and in others not. The problem come where the food producer is locked into a market and food production mechanisms are tied to that market.
It is the responsibility of food safety and public health officials to insure food safety at all levels and to use all the tools at their disposal to insure the consumption, production, delivery and presentation of food to the public no matter how its delivered, how its produced, how its presented, and how its consumed.
