Not as inexpensive as home made (perhaps) and smooth rather than chunky (but you can add your own favorite bits and pieces), Alvalle gaspacho is flash pasteurized. Sold in the cold case in just about every market. We keep a carton in our hotel room for in-room picnics or just a fast pick-me-up. I was surprised to hear from many French acquaintances that, yes, push-come-to -shove, they, too use Alvalle. Comes in several green versions also.
We bought and ate French cucumbers this week (peeled, but I always peel them if the skin is a little tough, which it was)
I've seen no reduction in the amount of fresh produce I've seen being bought, sold, or consumed in enormous salades composees anywhere.
It appears to be localized to north/northwest Germany, with the cases in other countries occurring in people who have recently returned from northern Germany.
