  We discuss the possibility that some recently measured anisotropic cosmic ray
components in the TeV-PeV energy range may be an indication of the ejection of
a peculiar type of matter. We present a model where a neutron star internal
transition with nuclear deconfinement of the quark content takes place. This
catastrophic event may cause a mass ejection process seeding the insterstelar
medium with droplets of quark matter, so called nuclearites. Neutralization of
these droplets in molecular clouds may drive the anisotropy since
quasi-rectilinear trajectories are allowed. Complementary information from
current experimental settings on earth or magnetic spectrometers on the ISS may
shed light on this exotic form of matter.
