Bought groceries around 4pm. Steak (Angus Ny Strips and Salad were in the cart) Placed in the fridge for later consumption. When I took 1 piece of the raw steak, the one underneath had a grey color under it, but the one I went to cook was all pink. 9pm rolls around, and I cook up the steak until brown all the way through, using salt and pepper to taste. Cut it up, mixed it into my salad. Used Italian dressing (olive garden). 1 hour later, I threw it all up. (I drank Ice Mountain water with it)
Bought steak last week, (exact type) cooked it, and ate it without any issues, but neither pieces of steak had any discoloration at all, so that could mean something.
Conclusion: Steak or the Salad caused me to get sick.
