It was opened in December actually lol. BUT, I had a carton of regular, organic milk that I bought in December too. The sell by date was Dec. 21. I used the last of it a few days ago and it never went bad. Isn’t that crazy? But I never drink coconut milk, so I wasn’t sure if the smell might be deceiving for it. I ended up just throwing it away to make room in the fridge. I forgot about cereal since the coffee cake I made had just come out of the oven lol.
My cousin tosses things out at least a day or two before that date on the carton. Her husband says food makes a brief stop in their frig before being thrown out.
