BTW, this is a picture of a Spanish cucumber field, published today in El Pais. I had never seen having to reach up to pick a cucumber.
These appear to be the “Armenian cucumber,” a long, ridged, thin-skinned variety that is supposedly burpless (for persons sensitive to cukes). Personally, I think it’s also flavorless...
Many of the pickers, particularly in El Ejido, are actually not Spaniards but come from various benighted and disease-ridden parts of the ME.
However, the contamination could have come from anywhere. Who knows?
The cucumbers are trellised, which is a much cleaner way to grow them.
