Anisakis infection in fish: An ecoparasitological study in different fishing grounds of the central-southern
Adriatic Sea

A
nisakis parasites arewidely detected inmarine organisms
and are responsible to cause a fish-borne zoonosis
through the consumption of larvae in raw seafood. Due to
either ancient or new trends in eating habits, a significant
increase of Anisakiasis has occurred, including Italy. Because
of its fame for being one of themost important fisherymarket
worldwide, the need to create the “
Anisakis
risk’s map”, as
suggested by EFSA, has become vital in order to guarantee
an high food security for customers. Main aim of this study
was to determine the distribution of
Anisakis
parasites in
fish caught in different central-southern fishing grounds of
the Adriatic Sea. Out of 2332 fish examined, composed of
several commercial species, an overall prevalence of 8.1%
for Anisakis larvae was detected. The results obtained were
compared with data available for the northern Adriatic
areas, which showed a total prevalence of 0.2%, in order
to find possible correlations with environmental and
ecological factors. As a result, the survey displayed notable
differences among fishing grounds, with more parasites
when moving southward. The differences were linked with
the hydrological, morphological and ecological features that
distinguish the different parts of the Adriatic Sea and divide
it into two ecosystems. The northern portion is defined as a
coastal and eutrophic area, both for its shallow waters and
for the Italian rivers that enter freshwater rich in nutrients.
The central-southern portion, instead, is considered as an
oceanic and oligotrophic ecosystem characterized by higher
depth and salinity, as well as reduced nutrient loads from
rivers. Consequently, these features strongly influence the
distribution and abundance of
Anisakis
’ hosts involved in
its biological cycle, leading to significant differences also in
the distribution of larval stages of the parasite in marine fish
populations.
