That doesn't sound right. 124ml of olive oil will probably do funny things to your shit and make you feel weird, but I very much doubt it'll kill you unless you inject it straight into your aorta.
To me, this says that they didn’t bother testing any doses higher than that. So, who knows how much you really need to ingest to see an effect. ¯_(ツ)_/¯
That value also seems pretty reasonable, since who would replace the milk of their morning cereal with olive oil.
