I am betting one million internet points that there will be some field with salad, bamboo shoots or similiar produce were they used sewage or manure to fertilize and then didn’t keep the minimum time till harvest and the processing plant didn’t wash them properly before putting them in the sandwiches.
This is the most common way of getting fecal E.coli bacteria outbreaks. Given the amount of people infected it is rather unlikely that it comes from a single employee not washing hands after shitting.
Either way this screams lack of proper hygiene inspections.
I’ve been in the facilities where they make these. Had to wash my hands like 5 times at separate stations before being allowed on the floor.
Turns out that the “green” in Greencore wasn’t about sustainability but rather the color your face turns an hour after eating one of their literal shit sandwiches!
Why would anyone buy prepacked sandwiches anyway? They’re expensive and you obviously never know what you get.
What’s the issue with buying some bread and preparing some at home? Cheaper, healthier and really doesn’t cost much time at all. Plus, this doesn’t use as much plastic.
Meal deals are a British staple. Many office workers will grab a sandwich, a snack, and a drink during a lunch break. That’s probably why this has made the news here, because if you wanted to poison the most people at the same time this is probably the best way.
As you already implied: when you’re not at home but travelling.
