Not disgusting, just a potential acquired taste to develop. I tried a worm spread for bread, was ok, but needs to be mixed very well into a paste in order to stomach it first.
But it's all in the mind. For example there's a delicacy here in Europe called wullocks that are boiled very slimy sea snails or mussels and oysters. I don't see much difference between that and a worm breadspread or a cricket burger actually.
I am from greece, yeah I know, snails are also a delicacy here. Never touched this shit and I hope I never will ^__^
