The dose makes the poison inferred

A reported mouse other LD50 for Linoleic acid is 280 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:

19.6 g
a median lethal dose scaled to 154 lb (19,600 mg)

“The dose makes the poison” is a cross-species estimate shown as neutral science, not a threshold anyone should act on. Real toxicity depends on the person, not body mass alone.
