  We explore the cosmological implications at effective level of matter
creation effects in a dissipative fluid for a FLRW geometry; we also perform a
statistical analysis for this kind of model. By considering an inhomogeneous
Ansatz for the particle production rate we obtain that for created matter of
dark matter type we can have a quintessence scenario or a future singularity
known as little rip; in dependence of the value of a constant parameter,
$\eta$, which characterizes the matter production effects. The dimensionless
age of this kind of Universe is computed, showing that this number is greater
than the standard cosmology value, this is typical of universes with presence
of dark energy. The inclusion of baryonic matter is studied. By implementing
the construction of the particle production rate for a dissipative fluid by
considering two approaches for the expression of the bulk viscous pressure; we
find that in Eckart model we have a big rip singularity leading to a
catastrophic matter production and in the truncated version of the
Israel-Stewart model such rate remains bounded leading to a quintessence
scenario. For a non adiabatic dissipative fluid, we obtain a positive
temperature and the cosmic expansion obeys the second law of thermodynamics.
