Depends: There are certain fish which are more risky depending on your gender and age because of mercury; others because they are poisonous unless properly handled (fugu, or pufferfish). In general, eating raw food is riskier than properly cooked. That being said, if the sushi is properly prepared, your risk of illness is generally low.

Tuna Tales: Likely never, unless you consumed enormous quantities of this fish. While tuna and several other large game fish tend to concentrate mercury and several other heavy metals in their tissues, much of this can be controlled by choosing the source of your fish. Purchasing tuna from reputable countries can ensure more quality in the fish you consume. This is also true of farmed fish like tilapia.

Mercury in fish: Some fish, however, contain high amounts of mercury -- enough to damage a fetus or newborn. That is why pregnant and nursing mothers must be very careful about the amounts and types of fish they eat. Young children should also avoid eating fish high in mercury. According to the fda, pregnant women and small children (under 6) should not eat more than 2 servings of fish each week.

Mercury in tuna: Mercury in canned tuna is higher in white than in light tuna. Pregnant women shouldn't eat any, and potentially pregnant women and young children should eat white tuna once a week or less, light tuna twice a week or less. http://www.consumerreports.org/cro/magazine-archive/2011/january/food/mercury-in-tuna/overview/index.htm no swordfish either: http://seafood.Ucdavis.Edu/pubs/mercury.Htm.

Blood test can tell: Since one does not know how much mercury is in the body without a blood test, getting the test is the easiest thing to do. If the level is in the normal range, then it doesn't matter how much fish was eaten earlier.
