Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

RNA interference targets arbovirus replication in Culicoides cells [PDF]

, 2013
Arboviruses are transmitted to vertebrate hosts by biting arthropod vectors such as mosquitoes, ticks and midges. These viruses replicate in both arthropods and vertebrates and are thus exposed to different antiviral responses in these organisms.

Faunistic inventory of the genus Culicoides (Diptera: Ceratopogonidae) in Mauritius Island, Indian Ocean: Diversity and spatial distribution of species of veterinary interest Inventaire faunistique du genre Culicoides (Diptera: Ceratopogonidae) sur l'île Maurice dans l'océan Indien: diversité et répartition spatiale des espèces présentant un intérêt vétérinaire

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 282-293, June 2026.
Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species
