A single meal containing phytosterols does not affect the uptake or tissue distribution of cholesterol in zebrafish (Danio rerio)

Aquaculture - Cholesterol - Cholesterol uptake - Phytosterols - Zebrafish

Increased plant oil inclusion in aquaculture feeds has led to higher dietary phytosterol concentrations and speculation about whether this affects the metabolism and health of the fish. The mechanisms of cholesterol absorption and how phytosterols may affect this is unknown in fish. Zebrafish (Danio rerio) were used to study the effects of phytosterols on the uptake and organ distribution of dietary cholesterol in fish. One meal of diets containing a constant addition of cholesterol (cold and [4- 14 C] cholesterol) and varying types and concentrations of phytosterols were fed to fish in individual compartments. The fish were not previously conditioned on the experimental diets. Activity of 14 C was then measured in water and fish tissues to quantify the tissue distribution and excretion of cholesterol. There were no effects of the moderate dietary concentrations of phytosterols on the excretion or tissue distribution of dietary cholesterol 24 h after the meal.

Recommendations and requirements for the management of foodstuffs including drinking water and
feedstuffs (but not other commodities) contaminated after a nuclear accident or a radiological event have been developed by
international bodies such as Codex Alimentarius Commission or European Union as well as by individual countries.
However, the experience fromsevere nuclear accidents (Chernobyl,Fukushima) and less serious radiological events, shows
that the implementation of such systems (based on criteria expressed in activity concentration) seems to be not fully suitable
to prevent several difficulties such as, for instance, stigmatization and even rejection attitudes from consumers or retailers
(anticipating the fears of consumers). Tofurther investigate the possible strategies and stakeholder expectations to deal with
this sensitive issue, a study has been launchedwithin the European research projectPREPARE-WP3. The overall objective
of this work, coordinated is to contribute to the development of strategies, guidance and tools for the management of the
contaminated products, taking into account the views of producers, processing and retail industries and consumers. For this
purpose, 10 stakeholder panels from different European countries have been set up. In addition, feedback experience from
the management of contaminated goods following the Fukushima accident has been provided by Japanese stakeholders.
This paper highlights the key topics tackled by the different European stakeholders’ panels
