Tick-bite that can cause meat allergy

Ticks of a certain species, from the southeast US, cause a painful and lasting allergy to mammal meat and dairy, in humans they bite. Due to global heating, the ticks are spreading north and have been seen in New York and Maine, close to the northern border of the US.

One could imagine that the spread of this allergy could reduce consumption of red meat and dairy thus curb global heating, but I don't think it would be enough to save civilization.
