  The cosmic metals are believed to originate from stellar and supernovae (SNe)
nucleosynthesis, dispersed into the interstellar medium (ISM) through stellar
winds and supernova explosions. In this paper, we present the clear evidence of
metal enrichment by a type Ic SN 2011jm in the galaxy NGC 4809, utilizing high
spatial resolution Integral Field Units (IFU) observations obtained from the
Very Large Telescope (VLT)/Multi Unit Spectroscopic Explorer (MUSE). Despite SN
2011jm being surrounded by metal-deficient ISM ($\sim 0.25 \ Z_\odot$) at a
scale about 100 pc, we clearly detect enriched oxygen abundance ($\sim 0.35 \
Z_\odot$) and a noteworthy nitrogen-to-oxygen ratio at the SN site. Remarkably,
the metal pollution is confined to a smaller scale ( $\leq$ 13 pc). We posit
that the enhanced ionized metal stems from stellar winds emitted by massive
stars or previous SNe explosions. This observation may represent the first
direct detection of chemical pollution by stellar feedback in star-forming
galaxies beyond the Local Volume.
