The strain was earlier identified as belonging to H. faecalis species, showed no toxigenic potential, and harboured no acquired antimicrobial resistance genes. Therefore, based on previous assessments, the additive was considered safe for the target species, consumers and the environment. Regarding the user safety, the additive is not a skin\/eye irritant but a skin and respiratory sensitizer. Inhalation and dermal exposure were considered a risk. The Panel concluded that the additive has the potential to be efficacious as a zootechnical feed additive for calves for fattening\/rearing, other bovines, ovines, caprines, cervids and camelids at the corresponding developmental stage at 1\u2009\u00d7\u2009109\u2009colony forming unit (CFU)\/kg complete feed and 5\u2009\u00d7\u2009108\u2009CFU\/L water for drinking.<\/jats:p>","DOI":"10.2903\/j.efsa.2026.10353","type":"journal-article","created":{"date-parts":[[2026,10,12]],"date-time":"2026-10-12T09:02:11Z","timestamp":1791795731000},"source":"Crossref","is-referenced-by-count":0,"title":["Safety and efficacy of a feed additive consisting of Heyndrickxia faecalis DSM 32016 (TechnoSpore50\u00ae) for calves for fattening\/rearing, and other bovines, ovines, caprines, cervids and camelids at the corresponding developmental stage (Biochem Zusatzstoffe Handels\u2010 und Produktionsgesellschaft mbH)"],"prefix":"10.2903","volume":"24","author":[{"name":"EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP)","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto Edoardo","family":"Villa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanna","family":"Azimonti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleftherios","family":"Bonos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrik","family":"Christensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mojca","family":"Durjava","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birgit","family":"Dusemund","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronette","family":"Gehring","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boet","family":"Glandorf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryline","family":"Kouba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"L\u00f3pez\u2010Alonso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Marcon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanna","family":"Martelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Nebbia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alena","family":"Pechov\u00e1","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Prieto\u2010Maradona","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katerina","family":"Theodoridou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasileios","family":"Bampidis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Montserrat","family":"Anguita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo Lorenzo","family":"Innocenti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordi","family":"Ortu\u00f1o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Mountricha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"10.2903\/j.efsa.2026.10353_ref1","doi-asserted-by":"crossref","unstructured":"EFSA (European Food Safety Authority) .
