I would be cautious though. Make sure you clean the trash can out with a bleach/water solution, rinse it out, and then let it air dry for a day or two. Just to make sure there aren't any leftover chemicals or organics in the bucket. Still, if it were me, i wouldn't buy anything that wasn't food grade rated. But on the contrary, i do store water in 5G paint buckets. But i did clean it out with a bleach/water solution first off like i mentioned above.
