European Food Safety Authority — Safety and efficacy of Panaferd-AX (red carotenoid-rich bacterium Paracoccus carotinifaciens) as feed additive for salmon and trout

Safety and efficacy of Panaferd-AX (red carotenoid-rich bacterium
Paracoccus carotinifaciens) as feed additive for salmon and trout1
Scientific Opinion of the Panel on Additives and Products or Substances used in Animal Feed

(Question No EFSA-Q-2006-173)
Adopted on 18 September 2007

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Panaferd-AX. The product is a feed additive consisting of dried sterilised cells of a red carotenoid-rich bacterium (Paracoccus carotinifaciens) intended to provide farmed Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) with a source
of astaxanthin which confers the characteristic red colour to the flesh. Panaferd-AX contains around 4 % total red carotenoids, predominantly astaxanthin (2.2 %), adonirubin (1.3 %) and
canthaxanthin (0.4 %).

In salmon and rainbow trout astaxanthin, deposition in flesh from Panaferd-AX was less efficient than that from synthetic astaxanthin. However, equal astaxanthin doses from both sources resulted in a comparable flesh pigmentation in the dose range of 20 to 100 mg astaxanthin kg-1 feed, due to the contribution of the other red carotenoids, mainly adonirubin and canthaxanthin, which are also demonstrated to be deposited in fish flesh. The technological
and organoleptic properties of flesh from Panaferd-AX-treated fish were not different from those treated with synthetic astaxanthin.
Panaferd-AX, at dietary incorporation rate of 12.5-fold greater than the proposed maximum incorporation rate (0.4 %) is safe for salmonids (trout and salmon). Paracoccus carotinifaciens is not a known pathogen, and no other concerns have been identified either in the limited literature available or in the data submitted in the dossier.

Ornamental Fish International article – Genetically Modified Organisms In the Aquatic Trade?

Svein A. Fosså, Vice-Chairman, OFI

Science has long since brought us to the point where transferral of genes from one species to another is becoming everyday practice in many areas. The construction of GMO’s (Genetically Modified Organisms) has become a welcomed tool in medical production (various medicines, antibiotics, human spare parts, etc.), and it finds increasingly more uses in agriculture and food production. We get faster-growing crops, plants with integrated biological pest controls and disease resistance, plants with reduced need for fertilisers, as well as extended environmental tolerance and increased nutrient values in plants, as well as animals. Soon, GMO’s – fluorescent Zebra Fishes and Medakas for a start – will be ready also for introduction to the aquatic trade. Are we prepared for this?

Through the study of tropical fish, Scientists learned of the genetic basis of some cancers

In the 1920s, the American biologist Dr. Myron Gordon and German biologists Haussler and Kosswig independently discovered that inter-species hybrids of a particular strain of the platyfish, Xiphophorus maculatus, and the swordtail, Xiphophorus helleri, developed cancers virtually identical to malignant melanomas in man (reviewed here). They traced the origin of these tumors to pigment cells of a platyfish color pattern consisting of black spots on the dorsal fin. Genetic studies demonstrated that melanomas developed only in hybrids that had replaced both copies of a platyfish regulatory gene with swordtail forms that could not control proliferation of the platyfish pigment cells (reviewed here). This animal model was one of the first to prove that some cancers were inherited diseases; after 65 years, these fish still are used in cancer research in the United States, Germany, Canada and Japan.
