SCP-### in human host blood.

Item #: SCP-XXX

Object Class: Euclid

Special Containment Procedures: No less than four(4) Mustelus antarcticus infected with SCP-XXX are to be kept in a locked, reinforced plexiglass tank measuring 3m x 3m x 2m. Tank specifications and maintenance, feeding schedule and general care are otherwise standard for keeping large, salt water fish.

Biopsies are to be taken weekly and monitored for presence and possible mutation of SCP-XXX.

Upon death of a host or lack of SCP-XXX in a biopsy, host is to be immediately incinerated and a new Mustelus antarcticus is to be introduced to the tank after being infected with SCP-XXX.

Isolated samples of SCP-XXX are also to be kept in locked frozen storage.

Description: SCP-XXX is a species of parasitic protazoa that uses Humans as an intermediate host. SCP-XXX is suspected to have mutated from ██████████-█████, a parasite found in sharks and other carnivorous fish farmed for human consumption.

SCP-XXX's life cycle, when transferred from fish host to fish host acts indistinguishably from ██████████-█████, however, when infected, uncooked tissue is ingested by a human, the life cycle is described below:

Stage one: Infected cyst is ingested by human host. Cyst releases parasite cells into digestive system.
Stage two: Parasite cells penetrate gut lining and infest bloodstream, invading blood cells and multiplying.
Stage three: Parasite cells form cysts in brain, liver and muscle tissue.

When infection progresses to stage three, human host displays mild paranoia, irritability and slight, various personality changes as well as severe aversion to fresh water. Stage three outward symptoms will last for approximately one week before subsiding, at which point the cysts break down and the parasite is considered benign.

If the host comes within close proximity to a large body of salt water (proximity is estimated at average range from which the host can smell the salt water) during stage three of infection, host is compelled to enter the water. Compulsion is described as "mild, but persistent". When coming in contact with salt water, host will begin to bleed from mouth, nose, ears, eyes and anus. Host will continue to swim until exsanguination.

SCP-XXX was first brought to the Foundation's attention after a series of incidents in █████, a small coastal fishing town in Australia. Within a space of 3 weeks in September 19██, 6 individuals were reported missing after strange behaviour. Finally a local fisheries worker was seen, fully clothed, deliberately running into the waves at a popular surf beach. Only minutes later he was spotted by a surfer, floating face down more than half a mile from shore. When lifeguards were dispatched, the victim was found in a section of the water richly mixed with his blood, although no trauma was evident.

An SCP Team was dispatched, retrieving the body. Upon performing an autopsy, Drs █████ and ████████ found the victim had be drained of almost exactly half of his blood supply. They also discovered several cysts in the victim's brain and liver. When studied, the cysts revealed SCP-XXX, which Dr ████████, having a background in parasitology, identified as ██████████-█████. The team then traced the infection from the local Japanese restaurant to [REDACTED] Fish Farm. After finding sharks infested with SCP-XXX at the facility and acquiring several samples for study, all existing fish were incinerated and employees [DATA EXPUNGED].

Since these events, no other cases of SCP-XXX infection have been recorded.

An unopened pack of SCP-XXX.

Item #: SCP-XXX

Object Class: Euclid

Special Containment Procedures:
SCP-XXX is to be kept in Standard, climate controlled Security Storage within Site-██. All separate packages of SCP-XXX are to be kept within the outer carton. With clearance from at least one Level 05, researchers are permitted to remove a single piece of SCP-XXX for research. Unless retaining it is a part of the research, the used piece of SCP-XXX is to be incinerated immediately after testing. Only one piece is to be released for research at a time. Once a package of SCP-XXX is depleted, packaging is to be retained along with outer carton.
