Salmon Poisoning Disease
What is Salmon
Poisoning Disease (SPD)?
SPD is a disease that makes dogs severely ill. Symptoms can
include fever, vomiting, diarrhea, bloody
diarrhea, lethargy, enlarged lymph nodes,
physical collapse and death. Dogs with SPD need to be
treated by a veterinarian. Illness usually
starts about 5-7 days after the dog eats or
SPD is not caused by a poison, it is caused by
infection from a bacteria and a parasite
together. SPD causes no harm to fish. The
parasite (called Nanophyetus) infects
trout at a fish farm. Inside these parasites
are bacteria (called Neorickettsia).
Dogs can catch the illness very easily when they
eat raw or undercooked trout. One dog caught the
disease after licking the ground where water had
dripped off of a trout. This disease is most
common in the Pacific Northwest area of the
Do Dogs in Los
Angeles County Get Sick with SPD?
Since 2006, at least 15 dogs in Los Angeles
County became severely ill after eating or
licking parts of raw trout. Two of them died.
The others received intensive treatment and
survived. The trout had been transported to LA
County from the Pacific Northwest for sport
Do People get
Salmon Poisoning Disease?
Humans can get infected with the parasite (Nanophyetus)
only if they eat raw fish, or if they do not
practice good sanitation in preparing fish. When
humans are infected, they experience mostly mild
diarrhea. Safe and sanitary fish handling
prevents this problem.
What Should I
NEVER ALLOW DOGS TO EAT ANY RAW FISH OR
REMEMBER – Dogs can smell fish that have
been buried to use as fertilizer! Keep dogs
away from buried fish!
Fisherman should always use excellent
sanitation when cleaning and preparing fish.
If your dog has eaten raw fish caught
from a local lake and becomes ill, mention
the fish to your veterinarian.
