https://doi.org/10.31396/Biodiv.Jour.2019.10.4.495.496

ABSTRACT
Anisakiasis is a zoonotical disease provoked by the nematodes belonged to the Anisakidae family. The trend of Anisakiasis cases increases continously, therefore a constant awareness of this topic is essential for the consumers' protection. An application for smartphones was carried out by the National Centre for Anisakiasis for this purpose. This work aimed at evaluate the impact of “Anisakis CReNA” app for consumers by the implementation of a survey. The results obtained revealed that the app developed has reached the goal established giving easy to understand and easy to consult information for the protection of consumers regarding the risks related to these parasites.

Determination of Chlorpyriphos in Sicilian peaches by Gascromatography-MSMS method coupled with quechers sample preparation procedure preparation
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.491.492

ABSTRACT
Chlorpyrifos is an organophosphate pesticide used to kill a number of pests including insects and worms. It is considered moderately hazardous to humans by the World Health Organization and is harmful for these classes of animals. Gas chromatography tandem mass mass spectrometry (GC-MS) was used for the quantification and confirmation of Chlorpyrifos pesticide residues in peaches. The analysis carried out on peach samples confirmed that chlorpyrifos are widely used in Sicilian territory so that 34 percent of the samples were contaminated by the pesticide.

Sulphite’s determination in equine meat and its preparations
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.489.490

ABSTRACT
Sulphites are antimicrobial and antioxidant substances recognized as additives. Furthermore, these chemicals may reduce the nutritional quality of food by interacting with some vitamins such as nicotinamide, folic acid, thiamine and pyridoxal. An ionic chromatography with conductivity suppressor detector, after rapid distillation method was carried out for the quantitative determination of sulfites in food products. On two hundred samples of equine meat, we revealed that 23% of the analyzed samples are above the limit allowed by law. Sulphites are used illegally with the purpose of obtaining and maintaining the aesthetic and commercial characteristics.

New report of Anikasis larvae from Blunthead Puffer, Sphoeroides pachygaster caught off Strait of Sicily
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.475.478

ABSTRACT
Aim of the present paper was to report and identify by morphological and molecular methods the presence of anisakid L3 larvae found in 7 specimens of Sphoeroides pachygaster caught off Strait of Sicily from 2012 and 2015. Nematode larvae (n=9) were collected from three fish samples: the larvae were morphologically identified as belonging to the genus Anisakis Type I and, stored in 70% ethanol, were underwent molecular identification at species level by PCR- RFLP analysis of the rDNA (ITS-1, 5.8S gene, and ITS-2) region. Sequencing of ITS regions and comparison with sequences in GenBank were also performed. The parasites were molecular identified as belonging to A. pegreffii that is the predominant species in Mediterranean Sea. This is a new report of Anisakis sp. in S. pachygaster. The blunthead puffer Sphoeroides pachygaster is a fish species of Atlantic origin: in the last years there are indeed numerous reports of this alien fish species in the Mediterranean included Italian Seas. The presence of the species Anisakis pegreffii may support the hypothesis of complete adaptation of S. pachygaster in the Mediterranean Sea.

Sulphite’s determination of Mediterranean Red Shrimp (Aristaeomorpha foliacea), in ionic chromatografy
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.469.470

ABSTRACT
In the red shrimp (Aristaeomorpha foliacea), sulphites are added because they block the activity of an enzymatic complex responsible of shrimp’s browing and maintain the aesthetic and commercial characteristics. An ionic chromatography after rapid distillation method was carried out for the quantitative determination of sulfites in food products. On 100 samples, only 0.7% were below the detection limit, 12.7% were above the limit allowed by law, 86.6% of samples were below the maximum permitted by law.

Detection of Anisakidae larvae in fish products commercialized in Sicily
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.465.468

ABSTRACT
In this work a total of 1331 fish samples belonging to 15 species (Engraulis encrasicolus, Alaccia aurita, Loligo vulgaris, Trigla lyra, Conger conger, Merluccius merluccius, Zeus faber, Lophius piscatorius, Sardina pilchardus, Lepidopus caudatus, Scorpaena scrofa, Scomber scombrus, Trachurus trachurus, Todarodes sagittatus, Trachinus draco) from Sicilian commercialized in Sicily (FAO 37, FAO 37.1.3, FAO 37.1.1, FAO 37.2.2, FAO 37.3, FAO27, FAO 41, FAO87), were examined for the detection of Anisakidae larvae and molecular identification. The fish samples were examined for the research of nematodes by visual inspection and digestion method according to the EC Regulation 2075/2005. Detected larvae were subjected to morphological identification through the optical microscopy. Subsequently, the DNA was extracted and the molecular identification of the larvae was conducted by RFLP-PCR of the nuclear ITS region (ITS-1, ITS-2 and 5.8 S subunit). The polymerase chain reactions targeting the cytochrome c oxidase subunit II (cox2) was performed and subjected to sequence reaction. A number of 370 larvae have been identified at species level, of which 330 belong to the Anisakis pegreffii, 23 to the Anisakis simplex sensu strictu, 6 to the recombinant genotype Anisakis pegreffii/simplex s. s., 1 to Anisakis physeteris and 10 to Hysterothylacium fabri. The data obtained provide interesting reflections on the presence of parasites belonging to the Anisakidae family in fishery products marketed in the Sicilian territory. These findings are an excellent tool for assessing and preventing possible risks due to the consumption of these products.

Investigation on the presence of Dioxins in the Sicilian Sheep’s milk
https://doi.org/10.31396/Biodiv.Jour.2019.10.4.463.464

ABSTRACT
Our studies were conducted in 2016 and several sicilian sheep farms were involved. The goal of this research was to evaluate the possible use of sheep as a “sentinel” body to be used as a biological indicator for environmental biomonitoring of dioxins. For the determination of dioxins in sheep’s milk was used a method on high-resolution gas chromatography along with a high resolution mass spectrometry (HRGC/HRMS) in order to evaluate the existence of dioxins with concentrations exceeding the limits imposed by the EC Regulation 1881/2006. A total of 200 samples were analyzed, of which 14 samples exceeded the limits imposed by the EC Regulation 1881/2006: 3.0 pg/g fat sum of dioxins (WHO.PCDD/F-TEQ). It is conceivable that the proximity to high anthropization areas and industrialization, may have a positive influence on the propagation of dioxins in the environment having been detected values exceeding the allowed limit. The samples with low dioxin concentrations were analyzed, with values not exceeding the prescribed limit.
