  The role that quasiparticles play in a strong interaction system with
spontaneous symmetry breaking is examined. We find, using a non- perturbative
cluster decomposition method, that the quasiparticles do not saturate the
physical local observables at small distances. The fermion number density
serves as a clearcut example. A component due to localized random quantum
fluctuations of the order parameter(s) in the vacuum state and the
contributions of ``quasiparticles'' corresponding to other local minima of the
effective potential is needed. At large distances, the ordinary quasiparticle
picture emerges in the response of the system to classical background fields
but the above mentioned component acts as a source for them.
