Some Sleuth-Ramblings On The Topic Of Prepared Fresh Vegetables...
It would be tough to dispute that most of us would benefit from eating more fresh fruits and vegetables.  To this end there are many produce companies marketing pre-trimmed-cleaned and ready to plop on the table products.  But; are they good for you?

On the Upside
Perhaps a scantily washed fresh vegetable is better than none?  I think in many cases, yes.  While some might poo-poo how much time it takes to trim up a bunch of fresh carrots, there are many of us that say, 10 minutes here, 10 minutes there and now you're talking about spare time for a real life. 

Another perhaps flimsy" plus is the pre-measured package makes for easier portion evaluation and control.  Many of us appreciate pre-packaged measurements that help us to easily provide proper serving sizes.

And Now For The Bad
We've seen a significant increase in bacteriological illnesses from fresh packaged foods.  The problem seems to be with the "wash water" and the washing equipment 

Is it really Fresh?  I often wonder how long ago this produce was plucked from the earth.  I mean, It does have go through additional processing steps of washing, packaging, sealing etc.  This processing step is another potential delay in getting fresh produce from the farm to your table.

And Now.. My Take On the Topic
I don't like buying pre-packaged vegetables.  I want to select them myself from the pickings at my farmer's market or grocery store.  I'm not enamoured with having to wash and prep them but somehow I feel like the food I put on the table is the freshest, and cleanest it can be.

I suppose as an option you can wash the pre-washed vegetables and somehow reap the other convenience benefits.

I'd write more on this topic but I have to go wash out tonight's spinach...........................
