The rapeseed oil isn't considered toxic anymore, since they take steps to remove the erucic acid from it, by growing canola bred to contain very little of it. https://en.wikipedia.org/wiki/Rapeseed_oil#Erucic_acid https://en.wikipedia.org/wiki/Rapeseed_oil#Erucic_acid While it says it's "generally considered safe", I prefer not to take any chances, just like I prefer to avoid plastic containers for my food, especially if hot (even though some plastics are "microwave safe"). --- I realize wikipedia isn't the greates of sources. Here are two more NIH https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9962393/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9962393/ Says it doesn't seem to be toxic in low quantities, but should be investigated more. To me, that means "rather avoid if possible". -- European Food Safety Authority says roughly the same: https://www.efsa.europa.eu/en/efsajournal/pub/4593 https://www.efsa.europa.eu/en/efsajournal/pub/4593
