POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) IN SEAFOOD CAUGHT OFF IN NAPOLI GULF (ITALY)
R. Marrone,R. Mercogliano,G. Palma,C. Chirollo
Italian Journal of Food Safety , 2011, DOI: 10.4081/ijfs.2011.1s.61
Abstract: Benzo(a)pyrene and other 12 polycyclic aromatic hydrocarbons (PAHs) were determined by high performance liquid chromatography (HPLC) with fluorescence detection in different seafoods (Merluccius merluccius, Arnoglossus laterna, Scomber japonicus, Eledone moschata and Penaeus kerathurus) collected along the coast of Napoli gulf (Italy). The results showed that Bap levels exceeded the limit fixed by EU Regulation 1881/2006 in several species and the concentrations of PAHs were higher in winter than in summer season. The presence of carcinogenic PAH in fish is dangerous to human health and should be seriously considered.
POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) IN SEAFOODS CAUGHT IN CORIGLIANO CALABRO GULF (CS,ITALY)
R. Marrone,G. Smaldone,T. Pepe,R. Mercogliano
Italian Journal of Food Safety , 2012, DOI: 10.4081/ijfs.2012.3.41
Abstract: Polycyclic aromatic hydrocarbons (PAHs) were determined by high performance liquid chromatography (HPLC) with fluorescence detection in seafoods (Merluccius merluccius, Arnoglossus laterna, Scomber japonicus, Penaeus kerathurus, Eledone cirrhosa) collected along coasts of Corigliano Calabro gulf (Calabria Region - Italy). The results showed that Bap levels exceeded the limit fixed by EU Regulation 1881/2006 in only four samples of Merluccius merluccius, Arnoglossus laterna and Scomber japonicus particularly. PAH concentrations detected in samples caught in winter were higher than those found in summer.
ENVIROMENTAL HYDROCARBON CONTAMINATION IN RICOTTA AND MOZZARELLA DI BUFALA CHEESE
R Mercogliano,A De Felice,C Chirollo,R Marrone
Italian Journal of Food Safety , 2010, DOI: 10.4081/ijfs.2010.8.45
Abstract: Polycyclic aromatic hydrocarbons (PAHs), mainly formed by anthropogenic activities, are ubiquitous environmental contaminants. Due to environmental contamination and their chemical properties they migrate through the human food chain. Aim of this study was the evaluation of PAHs in ricotta and mozzarella di bufala cheese, produced by milk of buffalo collected in three farms, located in a high contaminated area in Campania because of a waste treatment plant and illegal waste incineration. 11 PAHs were identified both in milk and dairy products. Carcinogenic hydrocarbon benzo(a)pyrene were found in a range including 0.42- 12.96 μg/kg and dibenzo(ah)anthracene 0.21-10.08 μg/kg. Anthracene showed higher concentrations than the other PAHs (45.23-436.85 μg/kg).
“COLATURA DI ALICI “ CETARESE: EVALUATION OF AMINIC PROFILE
R. Mercogliano,R. D’Ambrosio,A. De Felice,C. Chirollo
Italian Journal of Food Safety , 2008, DOI: 10.4081/ijfs.2008.2.45
Abstract: “Colatura d’alici”is a speciality made in Cetara, a clear ,amber-coloured liquid that has sharp taste, prepared with the juice coming from the anchovy salting process. The anchovies are caught in the Gulf of Salerno between the mounths of March and July. The colatura is ready at the beginning of December. Histamine poisoning, a food-borne chemical intoxication caused by the consumption of food containing toxic levels of histamine, is a syndrome commonly associated with the consumption of seafood beloging to the Engraulidae and some fish families. Histamine and biogenic amine levels were determined in “colatura di alici di Cetara”. The amine was separated in a HPLC/FL system. Histamine level were lower than the law limits only in one of the examinated products. A reduction of the histamine and amine levels in colatura cetarese can be obtained using a determinate salt concentrations and changing way of seasoning.
HYDROCARBON CONTAMINATION IN BREAST MILK: PRELIMINARY STUDY
R. Mercogliano,A. De Felice,G. Pezone,V. Raffone
Italian Journal of Food Safety , 2011, DOI: 10.4081/ijfs.2011.1s.67
Abstract: Polycyclic aromatic hydrocarbons (PAHs), mainly formed by anthropogenic activities, are ubiquitous environmental contaminants. Due to environmental contamination and their chemical properties they migrate through the human food chain, and can be transferred from mother to infant via breastfeeding. The presence of PAHs in breast milk collected from 16 lactating women living in urban and rural areas of Campania (Italy) was investigated. Results showed the presence of 14 hydrocabons. Carcinogenic benzo(a)pyrene and potential carcinogenic dibenzo(ah)anthracene were found at concentrations rancing from 0.3 to 37.6 μg/kg and from 0.5 to 47.0, respectively.
ANTILISTERIAL ACTYVITY OF LACTIC ACID BACTERIA ISOLATED FROM GILTHEAD BREAMS AND SEA BASSES FILLETS PACKAGED MAP AGAINST PRIMITIVE STRAINS OF LISTERIA MONOCYTOGENES
M. Barile,A. Mormile,R. Mercogliano,N. Murru
Italian Journal of Food Safety , 2011, DOI: 10.4081/ijfs.2011.1.23
Abstract: Listeria monocytogenes is the causative agent of listeriosis typically caused by ready-to-eat processed food that have a refrigerated shelf-life, but lightly preserved fish products also belong to a high-risk category. Aim of the work was to evaluate antimicrobial activity linked bacteriocin-producing of LAB isolated from gilthead breams and sea basses fillets packaged in modified atmospheres. Fifty-five LAB strains were screened against 21 strains of Listeria monocytogenes, 1 Listeria innocua held in the culture collection of Department of Zootechnical Sciences and Food Ispection (SIA) and submitted to antagonistic activity using the spot on lawn and the agar well diffusion assay. Lactococcus lactis sub. lactis Sa31 was able to produce bacteriocin in agar and different broth medium. The bacteriocin man31 showed sensitivity to trypsin, pronase E and papain, inactivation at temperatures ≥ 100°C, bactericidal mode of action and antilisterial act, rapidly. The bacteriocin man31 caused a reduction of L. monocytogenes c growth about log10 > 3 UFC/ml, when was applied on indicator strain at 20,480 AU/ml concentration, in vitro.
