  We investigate multiple Charlier polynomials and in particular we will use
the (nearest neighbor) recurrence relation to find the asymptotic behavior of
the ratio of two multiple Charlier polynomials. This result is then used to
obtain the asymptotic distribution of the zeros, which is uniform on an
interval. We also deal with the case where one of the parameters of the various
Poisson distributions depend on the degree of the polynomial, in which case we
obtain another asymptotic distribution of the zeros.
