“…The findings of the necropsy were due to the decubitus period and respiratory agony before the death of the animal. It is known that the more acute the intoxication, the fewer post-mortem findings will be identified [2,8].…”

Background:Botulism is a non-febrile intoxication resulting from the ingestion of Clostridium botulinum neurotoxins manifested by partial or complete flaccid paralysis of the musculature of locomotion, swallowing and respiration. The objective of this study was to report the first case of botulinum intoxication associated with osteopathy in the state of Acre, as well as to alert breeders and veterinarians to the incidence of this disease in cattle farming. Case: The present report is an outbreak of botulism in the municipality of Acrelândia, in the state of Acre, which resulted in the death of 16 Nelore beef cattle in approximately 30 days. The affected animals were females in reproductive phase maintained under extensive breeding system. The main clinical signs presented were weakness in the pelvic limbs, prostration, recumbency and death in less than 48 h. Only one animal, with similar symptomatology, was found alive and submitted to emergency therapeutic measures, but without success. During the necropsy of this bovine, no significant changes were found, only related to the decubitus and agony time, except for fragments of long bones visualized in the reticulum. Samples of bone particles, ruminal contents, reticulum, rumen and intestine fragments were collected for the detection of botulinum toxins by the mouse bioassay method, as well as brain and brain stem for differential diagnosis of rabies and bovine spongiform encephalopathy by direct immunofluorescence and immunohistochemistry, respectively. The samples were sent to the Laboratory of General Bacteriology of the Biological Institute, São Paulo, Brazil, and all the analyzes presented negative results. Discussion: One of the main risk factors for the occurrence of botulinum toxin is the presence of carcasses in the pastures, added to the deficiency of phosphorus and other minerals. The cattle develop the habit of gnawing bones and tissues from dead animals in the field. With this exercise, animals can ingest pre-formed toxins in corpses, as decomposing remains offer an anaerobic environment conducive to spore development and toxin production. Bovine females, in breeding, present greater nutritional need than adult males and younger animals. This is because the reproductive phase increases the demands of minerals, vitamins and organic compounds that participate in the female's reproductive physiological process. In this case, the inadequate supply of minerals may stimulate the osteopagic practice of cadaveric remains in the pastures, making the bovids susceptible to botulism. Diagnosis is established by means of clinical signs, epidemiological characteristics and absence of specific anatomopathological findings. Confirmation is given by the isolation of the toxin in the body of the diseased animal. However, the lack of detection of this does not rule out the possibility of occurrence of the disease, in view of the rapid passage of the neurotoxin through the hematogenous route and through the tissues before reaching the neuromuscular junctions. In suspect c...

“…Um alimento acidificado é um alimento de baixa acidez, onde se adiciona um ácido para que o pH final de equilíbrio seja menor que 4,5 e uma atividade de água acima de 0,85. Isto deve ser controlado até o produto não apresentar riscos de desenvolvimento do Clostridium botulinum (CERESER et al, 2008) e é comumente utilizado para produção de conservas. Como nestes ensaios o pH mostrou-se acima de 4,5, o crescimento de C. botulinum pode ser inibido pela embalagem permeável a gases, não possibilitando a formação de condições de anaerobiose durante o período de armazenamento.…”

O consumo de palmito minimamente processado tem aumentado devido à praticidade e atributos de frescor para o consumidor. A utilização de pupunha é interessante pela variedade não apresentar grande potencial de oxidação, mantendo a cor natural durante todo o período de armazenamento. O objetivo deste trabalho foi avaliar a qualidade do palmito minimamente processado em diferentes tratamentos com ácido cítrico e combinação de ácido cítrico e cloreto de cálcio através de análises microbiológicas, químicas e sensorial. Os palmitos foram descascados, lavados em água corrente e detergente neutro, sanificados com hipoclorito de sódio 50 ppm por 15 minutos, cortados no formato de rodelas e submetidos aos seguintes tratamentos: (1) controle, (2) imersão em solução de ácido cítrico 1 % e (3) imersão em soluções de ácido cítrico 1 % e cloreto de cálcio 1 %. Posteriormente, os palmitos foram acondicionados em bandejas de isopor e envoltas por filme PVC e saco plástico de polietileno, armazenados por 6 dias a < 10ºC. Os resultados obtidos foram satisfatórios quanto à contagem microbiológica e mostraram que ela pode ser diminuída pela ação de refrigeração, sanitização, embalagens e acidificação. Além disso, a qualidade sensorial do palmito foi preservada durante o período de armazenamento pela aplicação dos tratamentos. Palavras-chave: Palmito Pupunha. Processamento Mínimo.

The use of pupunha is interesting because this variety does not present great potential of oxidation, keeping the natural color during the storage period. The objective of this work was to evaluate the quality of the palmito minimally processed in different treatments with citric acid and the combination of citric acid and calcium chloride through microbiological, chemical and sensorial analyzes. peeled, washed, cut into slices and sanitized with hypochlorite solution. The palm hearts, washed in running water and neutral detergent, sanitized with sodium hypochlorite 50 ppm for 15 minutes, processed in slices, and subjected to the following treatments: control, immersion in 1% citric acid solution and immersion in 1% citric acid solutions and 1% calcium chloride. Afterwards, they were packed in styrofoam trays wrapped in PVC film and polyethylene plastic bag, stored for 6 days at <10 ºC. The results obtained were satisfactory in terms of microbiological counting and showed that it can be reduced by the action of refrigeration, sanitization, packaging and acidification. In addition, the sensorial quality of the heart of palm was preserved during the storage period by the application of the treatments. Keywords: Heart-of-Palm. Minimally Processed. Food Safety.

“…Las toxinas botulínicas son consideradas las más potentes, presentando una DL50 de 1 a 5 ng/kg 66 . Las esporas de C.botulinum son las formas más resistentes dentro de los agentes bacterianos, pudiendo sobrevivir por más de 30 años en medio líquido y, probablemente, más tiempo en estado seco 15 . Para la germinación de las esporas y la división celular se requieren condiciones anaeróbicas y un ambiente con nutrientes apropiados (altas cantidades de material orgánico) 7 .…”
