  We consider an implementation of the Elitzur-Vaidman bomb experiment in a
DC-biased electronic Mach-Zehnder interferometer with a leakage port on one of
its arms playing the role of a "lousy bom". Many-body correlations tend to
screen out manifestations of interaction-free measurement. Analyzing the
correlations between the current at the interformeter's drains and at the
leakage port, we identify the limit where the originally proposed
single-particle effect is recovered. Specifically, we find that in the regime
of sufficiently diluted injected electron beam and short measurement times,
effects of quantum mechanical wave-particle duality emerge in the cross-current
correlations.
