Stop putting open cans back in the fridge with foil on top 🥫🧊 Once a can is open, air reaches the metal and acidic food like tomatoes pulls tin and iron out of it, even in the fridge: in one study, tomato sauce and crushed pineapple left open in their cans in the fridge for 7 days hit 670 and 540 mg/kg of tin, over double Australia's 250 mg/kg limit, a level WHO food experts say can upset some people's stomachs. Lined cans pick up far less, but food safety authorities still say to tip leftovers into a clean plastic or glass container with a lid. Treat it like leftovers: eat or freeze it within 3 days of opening, and if it's been open longer, bin the food and recycle the can.
