However, its presence in animal source food products sold in the Guangdong Province (GD) of China, and the resultant dietary exposure have not been elucidated. To address this gap, 3,100 samples from seven food categories, including beef, pork, mutton, offals, broilers, hen eggs, and farmed freshwater fish, marketed throughout four geographical regions of GD, were collected from 2015 to 2018. Gas chromatography coupled with mass spectrometry was employed to detect PCP levels in these food matrices. PCP was found in all food categories, but the average contamination levels were low, ranging from 0.40\u00a0\u00b5g\/kg wet weight (ww) (hen eggs) to 5.85\u00a0\u00b5g\/kg ww (offals). However, higher concentrations of PCP were detected (\n                      <jats:italic>P<\/jats:italic>\n                      &lt;\u00a00.05) in animal source food from the North region. Additionally, a temporal declining trend was observed in this four\u2010year consecutive survey. The estimated human dietary exposure of PCP to population groups, including the general population and subgroups (male and female, children, and adults), was found to be far below the permissible daily intake (3\u00a0\u00b5g\/kg body weight). Therefore, the health impacts of PCP should be correspondingly low for local residents, based on current toxicological knowledge. Regional exposure patterns varied due to different extents of contamination in the four areas, and pork, broilers, and freshwater fish were the major sources of dietary PCP exposure.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practical Application<\/jats:title>\n                    <jats:p>As a persistent organic pollutant, pentachlorophenol (PCP) has serious impacts on human health.
