Hello Forum,

I am trying to document the safety of shelled walnuts specifically.  As a benchmark, the California Almond Board has vast resources and has achieved a high degree of consistency in log reduction in shelled almonds across the trade group.  It is easy to make the case for 4 log reduction.

 

It seems intuitive that the process of husking and shelling Walnuts is inherently removing layers of contamination and raw walnuts have been consumed for a long time with few documented outbreaks (all of which were packaged retail goods according to my search of the FDA enforcement records since 2006).

 

Fightbac.org also describes nuts that have had the shell removed as a RTE food.

I would like to justify in my risk analysis that the likelihood is low enough to consider shelled walnuts to not be a hazard that needs supply chain notice.

 

Any comments or suggestions are welcome.

Thank you.

Your fightBac reference only defines ready-to-eat as "foods that do not need further preparation before eating". That's not a characterization of risk that's a description of intended use.

 

Walnuts were implicated in an E. coli 0157 outbreak in canada in 2011 (14 cases): http://ucfoodsafety....iles/169530.pdf

 

Husking and shelling will provide a reduction of gross contaminants...just like it would for peanuts. IDC who you are, nuts are high risk until roasted or otherwise put though a validated kill step.

 

Don't have readily available data for outbreaks,  but recalls are certainly common for salmonella based on an enforcement report search.

Thanks for the data.

I will base the supplier approvals in part on their capacity to implement lethality steps and ability to provide a COA to back it up.
