It depends on the kind of Tuna
Canned light tuna has about .118 PPM, Albacore is .353 PPM of Mercury
If you weigh 120 lbs, one-4 ounce can puts you at about 40% of the daily recommended limit, if you weigh in at 170 lbs, you are at about half that.
It takes several months for Mercury to leave your system so it accumulates if you eat the tuna every day or so.
The limits are set by the EPA
The EPA reference dose (RfD) is defined as the amount of mercury a person, including sensitive subpopulations, can be exposed to on a daily basis over a lifetime without appreciable risk of effects.
The EPA RfD is 0.1 µg mercury per kg body weight per day. When using the mercury calculator at GotMercury.Org, this value (adjusted for a week of exposure) is the value to which your mercury levels are being compared.
This level corresponds to a blood mercury level of 5.8 ug/L or 5.8 parts per billion (ppb) mercury. Blood mercury levels below this value are considered to be without appreciable risk by the EPA.
There is a calculator for most fish at the following website:

Tuna fish is good for humans but fresh tuna is better than canned tuna. But you shouldn't eat to much tuna because you can get mercury off them.
Maybe, it depends if Jesus loves you
nobody knows
tuna is a type of fish and fish is bad for dogs beacause the fur starts to falll off and the dog gets sick -ana silva15
no it is not good it could choke them
Fish with high levels of mercury, like tuna and swordfish.
There are 2 good ways to do this. One is the smell. Fish smells fishy, yes, but bad fish smells really bad. There is a difference in the smell if it is bad. Second, the color. It will have a greenish color if it is really bad.
Tuna fish, IF you're planning to buy cat food that day or the next. Cats like it but it's kinda bad for them as human grade canned tuna has a high level of phosphorous, which can be dangerous to a cat if fed long-term.
Animals are neither good nor bad. They obey their instincts, unlike humans, who know what is right and wrong but still choose to do the wrong thing.
Assuming the tuna is fresh to begin with, probably a few hours to a day or so. Also, it will last longer sitting out if it is not in direct sunlight or by a window, stove, microwave, or heater, too.
It has a chemical that is bad for plants, animals, fish, and also humans. Eventually plants, animals, fish, and humans will be affected in some ways.
Yes, ozone molecules can be good and bad for humans. Good as in at ozone layer and bad at ground level.
tuna is very good scientists say that it increases brain power very fast and it contains omega 3 and a funny word called phuritombus which is in the juice which is good for the brain and relieves stress Important Addendum:The smaller the species, the better; large tuna have high concentrations of Mercury, which is extremely toxic. If you're buying canned tuna, "chunk light" has less mercury than "solid white".NAY
Its bad
