It isn't that cut and dry. Iceberg gets recalls as well.
When farmers/pickers have to poop, where do you think they go?
Where the products are stored after being picked, the processing plants...the entire supply chain is absolutely filthy.
Bag/clamshell greens give a lot of people a false sense of that their lettuce/salad/veggies being "clean" because they see "prewashed" on the package and don't wash the veggies...GROSS! Rinsing isn't cleaning.
Use a solution of vinegar and cold water to clean bag and fresh lettuce/veggies...soak for 2-5 minutes and rinse thoroughly.
P.S. Remember, too, we're in a pandemic so, there are very few inspections taking place. The regularity of inspections and how they were conducted were already on the decline and kinda unreliable in the best of circumstances. Now...well, yeah. SMH
