I haven't had any problems with infections from fresh/frozen strawberries, but once the beer warms up a bit you will get more fermentation from the added sugars. You could put campden tabs in there or pasteurize the beer or do something else to kill off the yeast completely, THEN add the strawberries, and then force carb. But if there's yeast in there, they will find and eat the sugar.
