Northern bonito labeling fraud found out (EN)
A team of researchers from the CEU San Pablo University proved the existence of fraud because of the substitution of northern bonito or albacore tuna (Thunnus alalunga) with species of lower commercial value.
With the help of an immunoenzymatic technique known as ELISA, the scientists determined that yellowfin tuna (Thunnus albacares), little tunny (Euthynnus alletteratus), bullet tuna (Auxis rochei), skipjack (Katsuwonus pelamis), bigeye (Thunnus obesus) and bonito (Sarda sarda) are being sold with albacore tuna label.
The Basque Country Government predicts a good bonito campaign (ES)
Bittor Oroz, representative of the regional ministry of Agriculture, Fisheries and Food, has stated today that the bonito campaign will be satisfactory this year. He has participated in a summer course in the Basque Country University where he has assured that the first data received are positive, what makes think that the campaign will be good.
Multicriteria-based ranking for risk management of food-born parasites (EN)
FAO, together with the World Health Organization, has recently published the book entitled Multicriteria-based ranking for risk management of food-born parasites.
Infectious diseases caused by food-borne parasites have not received the same level of attention as other food-borne biological and chemical hazards. Nevertheless, they cause a high burden of disease in humans, may have prolonged, severe, and sometimes fatal outcomes, and result in considerable hardship in terms of food safety, security, quality of life, and negative impacts on livelihoods. The transmission routes for food-borne parasites are diverse. They can be transmitted by ingesting fresh or processed foods that have been contaminated via the environment, by animals or people.
Anisakidae and anisakiasis is one of the cases addressed.

Agreeing frozen fish dates sparks hot debate (EN)
Consumers could be put off eating fish, if new EU rules governing the labelling dates of frozen fish are not better defined, the British Frozen Food Federation (BFFF) has warned.

PARASITE project addresses the antigenicity of Anisakis after heating conditions used in canning process (EN)
Industrial conditions used in fish canning are, by far, enough to kill parasite larvae in terms of temperature and time. However, some Anisakis simplex allergens are very stable to high temperature.
To assess the antigenicity of Anisakis allergens after heating conditions used in canning process, PARASITE project researchers from the Institute of Food Science, Technology and Nutrition (ICTAN-CSIC), Madrid Health System-SERMAS and the National Museum of Natural Sciences (MNCN-CSIC), have conducted an experimental trial. In the study, two tuna species, which are free of Anisakis infection in nature, have been artificially infected and subjected to temperature conditions similar to those used by the canning industry.After the experiment, it was found that samples had lost most of antigens, although some residual allergens remained after the heating conditions that could represent a health risk for those patients previously sensitized to thermally stable A. simplex allergens. Authors consider that further investigation is needed to assess the clinical relevance of these findings.
