It could just be me, but a skull and cross bones "poisonous" type icon seems more effective. I don't see the problem with using a symbol already associated with death/harm. I remember seeing a skull/bones icon as a kid and the message was clear. You could paint this in pink - or use in on a bike helmet - and the meaning isn't lost when labeled on a hazardous substance.
I don't think the same is true for the logo they chose.
I can also understand a skull/bones symbol rotated by any angle. Might it offend someone? Probably...what doesn't.
