Latest news this morning was not to purchase loose bulk fresh spinach either, because many if not most retailers purchase it in large bags before binning it. It's probably all been pulled & not available anyway.
This whole thing just keeps getting worse & worse, & the $$$$ & harvesting jobs endangered or lost in California is mindboggling. And let's face it - even when/if they pinpoint the reason behind this & resolve it, it's going to be a long, long time before people begin to trust the fresh & fresh bagged spinach & salad products again. Yesterday when I was at the supermarket, the bagged salad section was jampacked with produce & no one was even walking near it, let alone buying it. I did see lots of people with heads of lettuce & other greeens though - just nothing bagged.
Shpj4 - you live in California where all this is happening & haven't heard anything at all about this yet? California is one of, if not "the", largest producer of fresh spinach, & this is a huge blow to the industry. Even the BBCAmerica (from England) news has had it headlined. You need to get out more; that or get more news shipped in.
