Drain and rinse the tuna. The number of times you drain and rinse it is up to you, but draining and rinsing it at least once is recommended.
Use a can opener to open the can, but don’t remove the lid.
Holding the lid in place, flip the can over and hold it over the sink until all the liquid has drained.
Remove the top of the can, and be careful not to cut yourself.
Take the tuna out of the can and place it in a strainer or colander.
Rinse the tuna thoroughly with water, then press the water out using a clean hand or a paper towel.
