  The paper deals with a family of jump Markov process defined in a medium with
a periodic or locally periodic microstructure. We assume that the generator of
the process is a zero order convolution type operator with rapidly oscillating
locally periodic coefficient and, under natural ellipticity and localization
conditions, show that the family satisfies the large deviation principle in the
path space equipped with Skorokhod topology. The corresponding rate function is
defined in terms of a family of auxiliary periodic spectral problems.
