Methylmercury is a highly toxic organic compound that bioaccumulates and biomagnifies in the human body when absorbed by the gastrointestinal tract after ingestion.1 Thus, monitoring methylmercury levels in fish is crucial for protecting public health and preventing dramatic scenarios such as the Minamata disease crisis in Japan. In this study, three different species of wild caught fish – Sockeye Salmon (Oncorhynchus nerka) from Alaska, USA; tuna imported from Vietnam; and swordfish (Xiphias gladius) imported from Indonesia – were collected from a Harris Teeter grocery store in Washington D.C. Total mercury concentration was measured by ICP-MS and the analyzed samples’ concentrations were 19.8 ± 2.9 ppb, 2.67 ± 0.01 ppm, and 380 ± 9 ppb for Sockeye Salmon, swordfish, and tuna, respectively.

Mercury (Hg) and its compounds are considered as one of the ten major dangerous groups of chemicals. The content of mercury in the coat was 136 cats and 113 dogs in the territory of the Vologda Region in Cherepovets. The total mercury concentration in the wool samples was measured on a mercury analyzer RA-915 +. The values of the mercury index in cats range from less than 0,001 mg / kg to 13,00 mg / kg, in dogs from less than 0,001 mg / kg to 1,858 mg / kg. Statistical difference in the content of mercury in wool between cats and dogs was revealed. The Hg content in cats is 3,5 times higher than the dogs have. Comparison analysis showed the concentration of mercury in the wool of cats and dogs have no statistically significant differences. The authors noted that cats had 4 times more mercury who ate fish. The average content of Hg in the wool of dogs is slightly different for those who ate fish.

AbstractSalmonella spp. is the leading cause of zoonotic enteric diseases wich represents a public health concern worldwide. The incidence of zoo-associated salmonellosis is rather high due to the high prevalence and shedding of this bacterium from wild animals specially kept in stressful conditions. To determine the potential public health risk presented by zoo animals in Semnan, we investigated the prevalence of Salmonella serovars Enteritidis and Typhimurium among wild animal species kept in the zoo and pet shops. Totally, 152 fecal samples from species in the zoo and pet shops were collected and Salmonella prevalence and identification was assessed via standard bacteriologic culture methods, serotyping, multiplex-PCR and antimicrobial susceptibility testing. Overall, 21% (32/152) of the samples were confirmed positive for Salmonella and serotyping showed 12.5% (19/32) Salmonella serovar Enteritidis and 8.5% (13/32) serovar Typhimurium, respectively. All the Salmonella isolates were sensitive to Chloramphenicole, Flurefenicole, Meropenem, Ceftizoxime, Imipenem and Ampicillin, while resistance was observed in the case of Nalidixic acid (78%) as the highest resistance, Streptomycin (28%), Oxytetracycline, Neomycin, Furazolidone (each one 15%) and Lincospectin (9.3%). The high occurrence of multidrug resistance Salmonella in zoo and pet animals represents a potential threat to public health and requires strict surveillance and application of hygienic criteria.
