A report I heard on the radio stated that the e-coli comes from the manure that the spinach was grown in.
E-coli is apparently an animal by-product, meaning it comes from the intestines of the animal which the manure is used to grow the crops.
Gross!
Where I work we use horse manure all the time but it is steilized at extreme temperatures for many weeks to kill all bacteria.
Perhaps these food companies weren't taking that extra step

It's interesting to me thjat we haven't heard the name of the producer of these bagged spinach products yet.

I am guess it's a big manufacturer and they are being protected so far by the media
