RESUMEN

In the aquaculture industry, biocides are routinely used to treat parasitosis in fish, and researchers are continually developing sustainable alternatives that can replace these harsh chemicals. In this context, the objective of this study was to evaluate the effectiveness of a new natural compound, BiokosTM, for the treatment against Epistylis sp. in Carassius auratus fish. The infestation was identified by the presence of whitish plaques on the integument of five animals, and the diagnosis was confirmed through skin scrapings. BiokosTM is a lipopeptide derived from the bacteria Pseudomonas that can destroy the functionality of the cell membrane of ciliated protozoa. The action of BiokosTM does not harm animals and the environment because the compound degrades into amino acids and fatty acids within days. A 0.15 m3 (150 L) aquarium was treated with an Ich-AwayTM water conditioner manufactured by the Danish company Sundew ApS, which has BiokosTM as the active ingredient. Six tablets were added to the water daily for two days, and new skin scrapings were performed. The fish were clinically well and no longer possessed lesions or parasites. The results obtained indicate that BiokosTM can be an innovative and more sustainable alternative for controlling epistyliasis in ornamental fish.

RESUMEN

The objective of this study was to identify the determinants of fish consumption in the population that attends open-air street markets in the city of Santo André, SP, Brazil.We performed a survey, covering approximately 482 people in 49 street markets.It consisted of free-answer questions, half open choice and half multiple-choice options, for the identification and evaluation of socioeconomic factors that facilitate and hinder fish consumption.A descriptive analysis of the data and further tests were used to determine the association between variables and linearity with consumption, with a significance level of 5%. The most commonly cited types of fish consumed were hake, sardine and dogfish. The factors that facilitate the purchase and consumption of fish are listed as follows: a preference for purchasing fish at street markets, appearance, firmness, fresh presentation, frozen presentation, as well as the respondent's education and individual monthly income. Limiting factors were identified as the price and the presence of spines. Perishability, odour, ethnicity, proximity to points of sale of residence and work, gender, age, number of people in the household, presence of children and acquisition supermarket were not characteristics that influenced decisions about fish consumption.

RESUMEN

The genus Dermocystidium infects a wide range of animals. The host infection often occurs through the ingestion of endospores. The diagnosis depends on wet mounts and histopathological analysis of the affected tissue. The aim of this study was to investigate the incidence of Dermocystidium sp. infection on the skin of farmed striped catfish (Pangasianodon hypophthalmus) from a fish farm located in Fortaleza, Ceará state, northeastern Brazil. From these observations, we determined that 100% of the analyzed animals were infected with Dermocystidium sp. The wet mount and histopathology of the fish lesions revealed spore-filled cysts between the dermis and epidermis, encapsulated by connective tissue. Owing to a lack of research on the parasite and its prevalence among different fish species in Brazil and the rest of the world, additional studies are required to understand their endemicity in fish farms of Brazil, and consequently develop better disease prevention methods and increase the overall productivity.

RESUMEN

This study identified the parasitic species in juvenile freshwater finfishes during the fattening stage, from a fish farm located in the Zona da Mata (MG), southeastern Brazil, and revealed both macro and microscopical lesions in fish gills. A total of 172 juvenile fishes of different species (Oreochromis niloticus, Ictalurus punctatus, Ctenopharyngodon idella, Cyprinus carpio, Astyanax bimaculatus and Brycon amazonicus) were transported to a laboratory in São Paulo city. The fish were sedated and then euthanized for parasitological analysis. All fish were infected by at least one parasite species. Ten different species of parasites were identified: Apiosoma sp., Epistylis sp., Ichthyobodo sp., trichodinids, Piscinoodinium pillulare, Ichthyophthirius multifiliis, Tetrahymena sp., monogeneans, Centrocestus formosanus metacercariae, and Dermocystidium sp. The best management practices and lack of sanitary control were also discussed.

RESUMEN

More than 1.450 marine fish species are commercialized as ornamental fish and approximately 90% of these are wild-caught. Rainford's butterflyfish, Chaetodon rainfordi (McCulloch, 1923), is endemic to the western Pacific. This fish species belongs to one of the main ornamental fish families imported into Brazil. Haliotrema is a genus of the family Dactylogyridae. Species of this genus have very interesting host associations and geographic distributions. The aim of this study was to report on occurrences of exotic Haliotrema aurigae in diseased Rainford butterflyfish that were imported to Brazil. One Rainford's butterflyfish with suspected parasitic disease was euthanized and subjected to skin and gill scraping. The parasite specimens were mounted on semi-permanent slides with Hoyer's solution for morphological analysis of sclerotized structures. The hard-sclerotized structures of these specimens were compared and were identified as those of Haliotrema aurigae (Yamaguti, 1968). These results emphasize the importance of implementation of correct control measures at the country's borders, to avoid the introduction of exotic parasites. In addition, it can be emphasized that the easy adaptation of this parasite to new environments is a concern for ornamental fish farmers.

RESUMEN

Scuticociliatosis, caused by an opportunistic ciliate protozoan, is responsible for significant economic losses in marine ornamental fish. This study reports the occurrence of Uronema spp., parasitizing ten species of marine reef fish at an ornamental fish wholesaler: Blue green damselfish (Chromis viridis), Vanderbilt's Chromis (Chromis vanderbilti), Pennant coralfish (Heniochus acuminatus), Threespot angelfish (Apolemichthys trimaculatus), Goldspotted angelfish (Apolemichthys xanthopunctatus), Sea goldie (Pseudanthias squamipinnis), Orchid dottyback (Pseudochromis fridmani), Threadfin butterflyfish (Chaetodon auriga), Vagabond butterflyfish (Chaetodon vagabundus), and Bluecheek butterflyfish (Chaetodon semilarvatus). Diseased fish showed disorders such as hemorrhages and ulcerative lesions on the body surface. Histopathological analysis of the muscle, liver, gut, kidney, spleen, gills, and stomach revealed hemorrhages and degeneration of muscle fiber, vacuolar degeneration of hepatocyte, inflammatory process and granuloma in the liver, atrophy of intestinal villi, inflammatory process and granuloma in the kidney, melanomacrophage centers, as well as inflammatory process in the spleen, epithelial cells hyperplasia and granuloma formation in the gills, and vacuolar degeneration and eosinophils in the stomach. Due to the severity of the disease, it is necessary to implement biosecurity measures with rapid and accurate diagnosis to minimize the risk of economic losses caused by Uronema spp.

RESUMEN

Cryptocaryon irritans is an obligate parasitic ciliate protozoan of wild and cultured marine fish. It causes white spot disease, and infections with this pathogen can cause significant losses for aquarists and commercial marine cultures worldwide. This study reports the occurrence of C. irritans parasitizing the ornamental reef fish, yellowtail tang, Zebrasoma xanthurum. Six days after being introduced to a new environment, 11 yellowtail tangs had white spots scattered across their bodies and fins. Suspicion of infection with C. irritans was evaluated by scraping the skin to confirm clinical diagnosis. After confirmation, the yellowtail tangs were transferred to a hospital aquarium and treated with the therapeutic agent Seachem Cupramine® for 15 days. During the treatment period, the copper concentration was monitored daily. At the end of the treatment, none of the yellowtail tangs showed clinical signs of white spots on their bodies, and skin scraping confirmed the yellowtail tangs were no longer infected. Subsequently, the yellowtail tangs were released for sale.

RESUMEN

The capsalid monogenean Neobenedenia melleni is known as a lethal pathogen for captured marine teleost ornamental fish, if left untreated. This study reports the occurrence of N. melleni parasitizing four species of ornamental reef fish imported into Brazil and maintained in quarantine: Arabian angelfish (Pomacanthus asfur ), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus), and bluecheek butterflyfish (Chaetodon semilarvatus). Ten days after the beginning of quarantine, some fish showed behavioral alterations, such as irritability, and corneal opacity, which were rapidly diagnosed to be caused by monogenean parasites by body surface scraping. The fish from the same batch were treated with two applications of 2 mg L-1 praziquantel each at an interval of four days. Seven days after the first treatment, the mucus surface of the fish was re-examined, which did not reveal the parasites presence being delivered for commercialization.

RESUMEN

Ao longo do tempo foram desenvolvidos controles sobre os alimentos e seus processos a fim de torná-los seguros para o consumo humano. Os esforços para este fim, porém, não foram suficientes, tendo em vista o crescente número de casos de doenças alimentares. Pesquisadores identificaram e adaptaram conceitos derivados das ciências sociais, utilizando-os na segurança dos alimentos, criando assim diversas concepções de Cultura de Segurança dos Alimentos (CSA). Sabe-se atualmente que a CSA influencia a inocuidade dos alimentos e é considerada um importante fator de risco a ser administrado pelas organizações. O presente estudo teve por objetivo apresentar e analisar conceitos de CSA, seus autores e os elementos/fatores que os compõem. Também abordou os processos de desenvolvimento, avaliação e amadurecimento da CSA em estabelecimentos que manipulam alimentos no Brasil ou em todo o mundo. Foram identificados dezoito trabalhos que apresentaram diferentes fatores de CSA e quatro que aplicaram instrumentos de CSA no Brasil. Constatou-se que a utilização de ferramentas para caracterizar a CSA vem se aprimorando ao longo do tempo. Os autores mais recentes utilizam, frequentemente, abordagem mista de métodos de avaliação para tal finalidade. Concluindo, propõe-se neste trabalho um conceito mais refinado de CSA em relação aos já existentes e um novo elemento/fator para caracterizar a CSA nos estabelecimentos que manipulam alimentos no Brasil


Over time, controls on food and its processes have been developed in order to make them safe for human consumption. However, efforts to this end were not sufficient, in view of the growing number of cases of foodborne illnesses. Researchers have identified and adapted concepts derived from the social sciences using them in food safety, thus creating different concepts of Food Safety Culture (FSC). It is currently known that FSC influences food safety and is considered an important risk factor to be managed by organizations. This study aimed to present and analyze FSC concepts, their authors and the elements/factors that compose them. It also addressed FSC development, evaluation and maturation processes in establishments that handle food in Brazil or around the world. Eighteen studies were identified that presented different FSC factors and four that applied FSC instruments in Brazil. It was found that the use of tools to characterize FSC has been improving over time. More recent authors often use a methods mixed approach to assessment for this purpose. In conclusion, this work proposes a more refined concept of FSC in relation to the existing ones and a new element/factor to characterize FSC in establishments that handle food in Brazil

RESUMEN

Scuticociliatosis, which is caused by an opportunistic ciliate protozoan, is responsible for significant economic losses in marine ornamental fish. This study reports the occurrence of Uronema sp., which was found to be parasitizing three species of marine reef fish imported into Brazil and maintained in quarantine: Vanderbilt's Chromis (Chromis vanderbilti), blue-green damselfish (Chromis viridis), and sea goldie (Pseudanthias squamipinnis). During the quarantine period, some fish presented with behavioral disorders and hemorrhages and ulcerative lesions on the body surface. Histopathological analysis showed hemorrhages, inflammation comprising mononuclear and granular cells in the skeletal muscle, and necrosis of the skin and the secondary lamellae of the gills, and parasites were also observed in the renal capsule. The absence of transboundary measures available to prevent the occurrence of ornamental fish diseases is also discussed.

RESUMEN

Aquarium ornamental pet fish constitute a major segment in the pet industry, with the United States, Europe, and Japan dominating the market. There are approximately 1,500 marine fish species and over 4,500 freshwater fish species commercialized as aquarium ornamental pet fish. Fish are the fourth most common pet present in Brazilian homes. In Brazil, aquarium ornamental pet fish can be marketed and distributed from different parts of the Brazilian territory and the world. Commercialization and circulation of living animals without the use of adequate prophylactic management procedures enables dissemination of a number of agents responsible for infectious diseases. Aquarium pet fish can also carry pathogenic agents, of bacterial, viral, fungal, or parasitic etiology, that may have a zoonotic feature endangering the persons handling the animals. This review presents the main pathogenic infectious agents of bacterial, viral, and fungal etiology that affect aquarium pet fish, as well as the prevention and control measures to ensure sanitary excellence in this segment.(AU)


Peixes ornamentais de aquário representam um grande segmento no mercado de animais de estimação, no qual Estados Unidos, Europa e Japão dominam. São aproximadamente 1.500 espécies de peixes marinhos e em torno de 4.500 de espécies de água doce comercializados com fins ornamentais. O peixe é a quarta espécie mais comum nos domicílios brasileiros. Peixes ornamentais de aquário são comercializados e distribuídos em diferentes partes do território nacional e do mundo. O comércio e circulação de animais vivos sem o uso de procedimentos de manejo profilático adequados possibilita a disseminação de inúmeros agentes patogênicos. Peixes ornamentais de aquário carreiam consigo agentes patogênicos de etiologia bacteriana, viral, fúngica e parasitária, sendo alguns de caráter zoonótico colocando em risco pessoas que os manipulam. O objetivo desta revisão é apresentar os principais agentes infeciosos patogênicos - de natureza bacteriana, viral e fúngica - que acometem peixes ornamentais de aquário, bem como os métodos de prevenção e controle que permitam excelência no segmento.(AU)

RESUMEN

This study analyzed the ectoparasitic fauna of freshwater ornamental fish marketed by a wholesaler in the São Paulo city. This study was undertaken from January to December 2016. A total of 268 freshwater ornamental fishes of various species that showed signs of disease after arrival at the establishment were evaluated. From the individuals, ectoparasites were collected by scraping off the skin and gills and visualized using an optical microscope at increasing magnification of 40x, 100x, 200x, and 400x. Parasites were found in 220 animals (82%); 11 different parasites were recorded, which included Ichthyophthirius multifiliis, Monogenes, Metacercariae (Centrocestus formosanus), Epistylis spp., Chilodonella spp., Lernaea spp., Tetrahymena spp., Piscinoodinium spp., Trichodina spp., Ichthyobodo spp. and Argulus spp. The occurrence of the parasites in the establishment studied can indicates that the suppliers' lack of good sanitary and hygiene practices in the management of their facilities, consequently distributing infested animals and putting the whole supply chain at risk.(AU)


O presente trabalho analisou a fauna ectoparasitária de peixes ornamentais de água doce comercializados em um estabelecimento atacadista de peixes ornamentais na grande São Paulo no período de janeiro a dezembro de 2016. Foram avaliados 268 peixes ornamentais de água doce de diversas espécies que apresentaram sinais de doença após a chegada ao estabelecimento. Nos indivíduos foi efetuada a pesquisa de ectoparasitas por meio da raspagem de pele e brânquias e visualização em microscópio óptico em aumento 40x, 100x, 200x e 400x. Foram encontrados parasitos em 220 animais (82%) incluindo 11 parasitos distintos: Ichthyophthirius multifiliis, Monogêneas, Metacercárias (Centrocestus formosanus), Epistylis spp., Chillodonella spp., Lernaea spp., Tetrahymena spp., Piscinoodinium spp., Trichodina spp., Ichthyobodo spp. e Argulus spp. A ocorrência dos parasitas no estabelecimento em estudo pode ser indicativa da falta de boas práticas sanitárias e de higiene dos fornecedores no manejo de suas instalações e, consequentemente, na distribuição de animais infestados, o que coloca em risco toda cadeia.(AU)

RESUMEN

O Brasil possui legislação sanitária rigorosa na produção de alimentos, entretanto questões culturais frequentemente conflitam com as normas, como o abate clandestino de aves. Mesmo com toda a tecnologia empregada e rigor do sistema de inspeção brasileiro ainda verifica-se o consumo de aves provenientes desses abates. O presente estudo objetivou fazer uma análise crítica sobre a existência e funcionamento das "Avícolas" no município de São Paulo, identificar fatores facilitadores e discutir ações para mitigar os riscos sanitários dessa atividade. Utilizou-se abordagem qualitativa para análise de documentos e relatórios gerados nas rotinas de trabalho da Coordenação de Vigilância em Saúde da Prefeitura do Município de São Paulo e legislação vigente acerca do assunto. Estima-se aproximadamente 3900 estabelecimentos com condições estruturais e sanitárias irregulares, porém não há levantamentos e/ou registros. As aves não possuem procedência determinada ou certificações sanitárias. O ambiente é promíscuo e insalubre, situação agravada pela falta de cuidados dos colaboradores. Há eliminação irregular de resíduos do abate, ausência de programas de autocontrole e/ou boas práticas de fabricação. Concluiu-se que as Avícolas são informais, ilegais e clandestinas, impactam negativamente a Saúde Pública pela atividade desenvolvida em desacordo com as normas sanitárias, ambientais e trabalhistas


Brazil has strict sanitary laws in food production. However, cultural issues often conflict with the rules, such as clandestine slaughter of birds. Even with all the technology employed and the rigor of the Brazilian inspection system, we still observe the consumption of poultry from these slaughters. This study aimed to critically analyze the existence and functioning of poultry in the city of São Paulo, to identify facilitating factors and to discuss actions to mitigate the health risks of this activity. A qualitative approach used to analyze documents and reports generated in the work routines of the Health Surveillance Coordination Office of the Municipality of São Paulo and current legislation on the subject. There are approximately 3900 establishments without structural and sanitary conditions are estimated, but there are no surveys and / or records. The birds have no specific provenance or sanitary certifications. The environment is promiscuous and unhealthy, a situation aggravated by the lack of care of employees. There is irregular disposal of slaughter residues, absence of 77 Higiene Alimentar - Vol.32 - nº 285/286 - Novembro/Dezembro de 2018 self-control programs and / or good manufacturing practices. It was concluded that Poultry are informal, illegal and clandestine, negatively impact Public Health by the activity developed in disagreement with sanitary, environmental and labor standards

RESUMEN

Introduction: The most frequent demands on microscopic food analysis are allegations of consumers finding macroscopic foreign matter or suspecting the presence of undeclared ingredients on products labels. The byproducts and foreign matters detection are fundamental practice for indirectly verifying the conditions of food production. Objective: This study reports the processes of microscopic and molecular identification (PCR) of a foreign matter found in a meat pie after a consumer complaint, occurred in the city of Itapira, state of São Paulo, Brazil. Method: Two distinct procedures were used to identify foreign matter: macroscopic examination, following FDA standards, and polymerase chain reaction (PCR) technique to identify DNA extracted from foreign materials. Results: The macroscopic analysis identified animal taste buds composing the pie fillings, and the PCR test confirmed that they were of bovine origin. Conclusions: Macroscopic analysis and the PCR test allowed the identification of the type of foreign matters and confirmed its bovine origin, what was enough to characterize it as a fraud by the improper use of inferior tissues in the preparation of ready-to-eat pastry.


Introdução: Uma das mais frequentes demandas de análise microscópica de alimentos são denúncias de consumidores que encontram matéria estranha macroscópica ou suspeitam da presença de ingredientes não declarados no rótulo do produto. A detecção de subprodutos e matérias estranhas é uma prática fundamental para verificar indiretamente a condição de produção de alimentos. Objetivo: Este estudo relata o processo de identificação microscópica e molecular (PCR) de uma matéria estranha encontrada em um pastel de carne após queixa de um consumidor no município de Itapira, estado de SP, Brasil. Método: Dois procedimentos distintos foram empregados para a identificação da matéria estranha: exame macroscópico seguindo padrões estabelecidos pelo FDA e técnica de reação em cadeia da polimerase (PCR) para identificação do DNA extraído da matéria estranha. Resultados: A análise macroscópica identificou a matéria estranha como sendo papilas gustativas de origem animal, e o teste da PCR confirmou que as mesmas eram de origem bovina. Conclusões: A análise macroscópica e o teste da PCR permitiram a identificação do tipo de matéria estranha e confirmação de sua origem bovina, caracterizando a fraude pelo uso indevido de tecidos inferiores na preparação de pastéis prontos para consumo.

RESUMEN

Abstract The capsalid monogenean Neobenedenia melleni is known as a lethal pathogen for captured marine teleost ornamental fish, if left untreated. This study reports the occurrence of N. melleni parasitizing four species of ornamental reef fish imported into Brazil and maintained in quarantine: Arabian angelfish (Pomacanthus asfur ), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus), and bluecheek butterflyfish (Chaetodon semilarvatus). Ten days after the beginning of quarantine, some fish showed behavioral alterations, such as irritability, and corneal opacity, which were rapidly diagnosed to be caused by monogenean parasites by body surface scraping. The fish from the same batch were treated with two applications of 2 mg L-1 praziquantel each at an interval of four days. Seven days after the first treatment, the mucus surface of the fish was re-examined, which did not reveal the parasites presence being delivered for commercialization.


Resumo Neobenedenia melleni é conhecido como um parasito letal para peixes teleósteos ornamentais marinhos capturados se não tratado. Este estudo relata a ocorrência de N. melleni parasitando quatro espécies de peixes ornamentais importados para o Brazil: Arabian angelfish (Pomacanthus asfur), yellowbar angelfish (Pomacanthus maculosus), regal angelfish (Pygoplites diacanthus) e bluecheek butterflyfish ( Chaetodon semilarvatus). Dez dias depois do início da quarentena, foram observados irritabilidade e opacidade na córnea dos peixes que, foram diagnosticadas com N. melleni na superfície corporal. Todos os peixes foram tratados com duas aplicações de praziquantel 2 mg L-1 em intervalo de quatro dias. Sete dias após o início do tratamento, um novo exame parasitológico foi realizado o qual não revelou a presença dos parasitos, sendo liberados para comercialização.
