You're gonna get it in your yoghurt and food packed in tupperware though, as metal utensils can and will scrape some of the plastic off.

Anyway, they're already present in tap water, so your lettuce is also already infused with microplastics.

that's a good point about the tap water, and you're probably right about polystyrene yogurt cups and tupperware, though i still think you won't find any evidence of it unless you do the experiment yourself
