Large recall of lettuce from a California farm was issued recently. This recall covers 19 states and Canada. This is the latest recall over listeria contamination of fruits and vegetables. Also recently a recall of cantaloupe has cased deaths in the united states.
The use of ozone for bacteria reduction on fruits and vegetables is gaining popularity due to the ease of application and the non selective nature of ozone when used as an anti-microbial intervention. While it is difficult to know if ozone would have had a role in these applications, it is worth considering the implementation of ozone in food processing application before the recall steps are necessary.
