  This paper investigates how the nonzero temperature affects the differential
cross-section for mesons scattering in a Lorentz-violating extension of the
scalar electrodynamics. We initially discuss some features of the model and
extract the zero temperature Feynman rules. Temperature effects are introduced
using the Thermo Field Dynamics (TFD) formalism. It is shown that the
corrections induced on the meson scattering are very large in the
high-temperature regime. Furthermore, our results also suggest that temperature
effects may contribute to new constraints on the Lorentz-violating parameters.
