contents The recent paper [Science 382, 907 (2023)] reports on the measurements of shot noise in the heavy fermion strange metal YbRh2Si2 patterned into the nanowire shape. The authors claim that the observed shot noise suppression can not be attributed to the electron-phonon energy relaxation in a standard Fermi liquid model but rather indicates the failure of quasiparticle concept. In this comment, we discuss the inconsistency in the resistivity extracted from nanowire devices of different length which may turn out crucial in the analysis of shot noise suppression due to the possible contribution of spreading resistance.
