“…Meat is among the main sources of nutrients, such as vitamins and fats, and is an important food for human health. However, the amount of nutrients that make up it depends, among other factors, on the animal (age, weight and genetic factors), rearing system, well-being, transport logistics, climate, pre-slaughter process, supplementation, type of pasture and diet formulation (1)(2)(3)(4)(5)(6)(7)(8). Thus, there is a direct relationship between the producer's planning, animal husbandry, and the composition of meat, a vital source for humans.…”

IntroductionThe quality of meat, with a focus on compounds important for human health, is directly related to the rearing systems in which the animals are produced. The search for a balanced diet, with an emphasis on low cholesterol and adequate levels of vitamins, aligns with society’s emphasis on healthy eating, directly correlated with the importance of the offer made by producers for the cattle’s diet.Objective and methodologyThe objective was to verify the impact of different rearing systems, in the Eastern Amazon, during the rainy season, on the concentrations of vitamins (A, E) and cholesterol in the muscle (Longissimus lumborum) of crossbred Nelore cattle, castrated, aged between 24 and 36 months, and weighing between 410 and 628 kg. Twelve animals, from each of the three pasture rearing systems: native pasture in flooded areas of Monte Alegre; native pasture in a flooded area of Santa Cruz do Arari; and pasture cultivated on dry land in São Miguel do Guamá, all located in Pará, Brazil—were sampled in commercial slaughterhouses.ResultsA notable influence was observed in the concentrations of β-carotene (p < 0.01), α-Tocopherol (p = 0.02), β-Tocopherol (p < 0.01) and the combined sum of β-Tocotrienol and γ-Tocopherol (p < 0.01), as well as δ-Tocopherol (p < 0.01) when contrasting extensive with intensive systems (confinement). However, there was a difference in the content of vitamins and cholesterol between the isolated extensive systems, or between the four rearing systems (p > 0.05). Extensive systems, mainly in Monte Alegre, demonstrated greater amounts of α-Tocopherol and δ-Tocopherol.ConclusionOn the other hand, the intensive system exhibited higher levels of other investigated compounds, clarifying the nutritional variations generated by different livestock rearing practices in the region. Therefore, the results obtained are innovative in the Eastern Amazon, Brazil, in addition to inspiring the development of new research to meet other demands in this field, and achieve additional results, such as determining which meat, coming from cattle in production systems in the country, presents the better compositional quality of vitamins and lipids.

“…Mas além de seu papel histórico-cultural e características nutricionais o alimento cárneo por ser um alimento altamente perecível demanda muito cuidado sobre o processo higiênico-sanitário durante todas as fases de processamento, devido a alterações físicas, químicas e microbiológicas sofridas (Santos, Palma & Santana 2017). Por isso garantir a higiene no manejo, local de produção e distribuição destes produtos é imprescindível para se obter um alimento seguro de substâncias e micro-organismos nocivos à saúde de todos (Santos et al, 2021).…”

O consumo de carne bovina e bubalina está presente em vários lugares e culturas no mundo, principalmente por ser uma fonte importante de nutrientes de alto valor biológico, no entanto faz-se necessário que este alimento seja seguro, sem contaminações biológicas, físicas ou químicas. Desta forma o objetivo deste trabalho é avaliar as condições microbiológicas e físico-químicas das carcaças de bovinos e bubalinos dos dois abatedouros legalizados de Macapá, Amapá. Ao todo 50 amostras foram coletadas através de swabs e amostras de partes das carnes, juntamente a fiscalização da Agência de Defesa e Inspeção Agropecuária do Estado, posteriormente encaminhadas e analisadas nos laboratórios do Núcleo de Ciência e Tecnologia de Alimentos do Instituto de Pesquisas Científicas e Tecnológicas do Estado do Amapá (NUCTAL/IEPA) através dos métodos Adolfo Lutz (2008) A.O.A.C (2006) e MAPA (1999) seguindo os protocolos do referido núcleo que consiste na Instrução Normativa N°62, do Ministério da Agricultura. Para as análises microbiológicas, as amostras apresentaram percentuais totais de 6% para E. coli e 2% para Samonella spp. No entanto, as maiores contaminações foram para Staphyloccocus aureus que chegaram a 50% do total das amostras. Com relação a composição centesimal, apesar de ambas as carnes apresentarem similaridades, notou-se grandes variações em proporção de gordura, que podem sofrer influência diante do seu conteúdo em aminoácidos essenciais e sua digestão.

The increased demand for meat from wild animals for human consumption, as an alternative protein source, brings with it the need for research that demonstrates the quality of such product. The technical information about the meat from collared peccaries still needs studies and aiming to collaborate with the already existing knowledge, this research had as its objective to provide subsidies for evaluation of the sanitary quality of the meat from collared peccaries. Twelve animals were used, six males and six females, aged four to five months, from the breeding stock of the Federal Rural University of the Semi-Arid and, after euthanasia by a slaughter technique used in goats, the meat samples were collected through sterile swabs at the locations of the hind leg, loin, belly and axilla of each animal, totaling 48 samples. The maximum mesophilic count found was 1.9 x 103 CFU/ml, the total coliform and thermotolerant coliform counts were below the one determined in the legislation for meat from domestic animals, however, through biochemical tests, the presence of E. coli from the biotype 1 and biotype 2 was found, in seven and six samples, respectively. Search results for Salmonella spp. were negative in all samples and, as for Staphylococcus spp., only one sample had the count above the level allowed by law. The contamination load related to the bacteria E. coli proved to be high, making 13 samples unfit for consumption. Regarding the other data, the meat from young collared peccaries showed a low contamination load.
