As to ingestion, the rat LD-50 dose for sodium chloride is 3 grams per kilogram of body weight. ("LD-50" stands for "lethal dose 50%", the dose which kills 50% of rats.) For a 220 pound man (100 kg) that would be 300 grams, which is just shy of 12 ounces. The lowest published lethal dose (LDlo) for humans is one third of that.
