US: Ice cream as a catalyst for change in the produce industry? By Dr Bob Whitaker

Dr Bob Whitaker, PMA: You are probably thinking that is an odd title unless you have been monitoring the Blue Bell ice cream recall in recent weeks. Blue Bell hit the news back in mid-March when they recalled ice cream products from one of their production lines owing to contamination with Listeria monocytogenes (Lm). Flashing forward to the end of April, Blue Bell has recalled all of its products currently in the market made at all of its facilities due to potential contamination with Lm. It turns out that arriving at where this case is today has been the result of a long and complex, multi-state outbreak investigation that may reach back as far as 2010. There are currently 10 people sickened by this incident across four states (Arizona, Kansas, Oklahoma, and Texas) with three deaths (all in Kansas). All of the victims were elderly and had other underlying health issues and were hospitalized before developing listeriosis.

While this is a tragedy that we can all relate to, you may still be asking, what does this have to do with produce?

US: Seeking alternatives for reducing bacteria in fresh produce

Farm and Dairy: A team of researchers at Wayne State University have been exploring natural, safe and alternative antimicrobials to reduce bacterial contamination.
