Accordingly, their global consumption has increased. To meet this demand, finfish are now imported across large geographic distances. This poses several challenges, including the potential contamination of finfish with pathogenic bacteria, which can cause food-borne illnesses. Gamma irradiation is a potential solution with a history of reducing bacterial density in foods without compromising nutrients or taste. While some previous work has suggested that vitamin D is stable during irradiation, others have suggested that irradiation may reduce vitamin D. Importantly, these studies have not been completed in finfish tissue of commercialized species, which may offer cross-protection against any reduction in vitamin D. However, this has yet to be evaluated. In this study, three filets each of salmon and trout were dissected into multiple sections and each section was exposed to a different dose of gamma irradiation under both chilled (4\u00b0C) or frozen condition (\u221217\u00b0C). Here, we show that the stability of vitamin D during irradiation depends on finfish species and temperature in a dose-dependent manner. Specifically, we found that there was no significant change in vitamin D when trout was irradiated in the chilled or frozen state. Conversely, salmon showed a significant decrease in vitamin D when radiation doses exceeded 0.5 kGy in the chilled state and 2 kGy in the frozen state. Overall, our results indicate that irradiation of finfish may not reduce vitamin D concentration when applied at dosages of 0.5 kGy and 2 kGy or less in chilled and frozen conditions, respectively. Consequently, irradiation may represent a mechanism to increase the safety of consuming finfish while not impacting an important source of dietary vitamin D.<\/jats:p>","DOI":"10.1371\/journal.pone.0332867","type":"journal-article","created":{"date-parts":[[2025,9,26]],"date-time":"2025-09-26T17:39:20Z","timestamp":1758908360000},"page":"e0332867","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["The effect of gamma irradiation on the stability of vitamin D in select finfish species"],"prefix":"10.1371","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4152-5124","authenticated-orcid":true,"given":"Jessica S.","family":"Brown","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia R.","family":"Calvo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pujita","family":"Julakanti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fatima","family":"Mohiuddin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdullah Basir","family":"Khan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kemly","family":"Julien","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Varun","family":"Natarajan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonardo B.","family":"Maya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaylyn A.","family":"Keith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony P.","family":"DeCaprio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan","family":"Hollingsworth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Benso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2744-7390","authenticated-orcid":true,"given":"Robert P.","family":"Smith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2025,9,26]]},"reference":[{"key":"pone.0332867.ref001","unstructured":"USDA.
