With healthy kidneys the half life of salt in the body is about half a day, maybe less. Even with destroyed kidneys, excess will be emitted in sweat, assuming the patient exercises enough to sweat... The chronic high blood pressure problem comes from destroyed kidneys being unable to excrete the salt fast enough. Bacon being a rather low carb food (as long as you don't maple glaze it or whatever, which admittedly is delicious...) the problem kind of takes care of itself in that lower carb foods tend to be higher sodium but the lower carb levels result in less damage to the kidneys, and healthy kidneys are not bothered by sodium ... The worst case scenario would be "foods" that are both salty and high carb, which is mostly junk food and fast food.
