Purpose Animal production wastes are promising for use in agricultural production as a plant nutrient or soil conditioner. However, if not properly managed, they can contaminate the soil and plants, resulting in public health risks. Considering that the composting technique is recommended to ensure compost hygiene and agronomic viability, the present study aimed to evaluate the microbiological and parasitic load during the composting of residues from conventional and organic animal productions. Method The presence of Salmonella sp. and/or helminth eggs and the quantification of thermotolerant coliforms were determined in horse bedding and organic and conventional poultry litter during the process of composting. Results The initial load of thermotolerant coliforms was greater than 1017 MPN g-1 in the three raw materials. All of them showed a significant reduction in these bacteria at the end of the composting process, reaching 99.98%, 100.00%, and 99.80% in the horse bedding, organic poultry litter, and conventional poultry litter, respectively. All the fresh residues contained helminth eggs, with the horse bedding exhibiting the highest amount compared to the others. However, they all revealed an absence of helminth eggs at the end of the composting process. Salmonella sp. was absent in both the raw materials and the final compost. Conclusion Composting was effective in eliminating helminth eggs and reducing thermotolerant coliform levels. However, the final composts retained a higher pathogenic microbial load than that required by the current Brazilian legislation for use in agriculture.

Abstract - The aim of this work was to evaluate the effect of single and multiple pre-harvest spray aminoethoxyvinylglycine (AVG) applications with or without ethephon, in ?Baigent? apple trees cultivated under anti-hail screen and harvesting date on fruit quality after storage. The experiment was conducted in a commercial orchard in the municipality of Vacaria/RS, in the 2014/15 and 2015/16 harvests. Treatments consisted of: control (plants sprayed with water); AVG (125 mg L-1, 30 days before the predicted harvest date; BPHD); ethephon (120 mg L-1, seven BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD) + ethephon (120 mg L-1, seven BPHD). Fruits of all treatments were harvested at commercial harvest (harvest 1) and after 14 days (harvest 2). Fruits were evaluated after four months of cold storage (0.5 °C ± 0.2 °C and RH 92 ± 5%). The use of AVG, regardless of single or multiple applications, reduced ethylene production rate, skin yellowing, farinaceous pulp and senescent degeneration incidence and maintained higher pulp firmness values and pulp penetration and skin rupture strength. Ethephon provided fruits with higher farinaceous pulp incidence. Fruit treated with AVG, regardless of single or multiple application and combination with ethephon, presents better quality after cold storage.Index terms: Malus domestica, growth regulators, ethylene, cold storage Qualidade pós-colheita de maçãs ?Baigent? em função da formade aplicação de aminoetoxivinilglicina e etefomResumo - O objetivo deste trabalho foi avaliar os efeitos da aplicação pré-colheita de aminoetoxivinilglicina (AVG), em dose única ou parcelada, combinado ou não com etefom, em macieiras ?Baigent?, e da data de colheita, sobre a qualidade dos frutos, após o armazenamento. O experimento foi conduzido em pomar comercial, no município de Vacaria-RS, nas safras de 2014/2015 e 2015/2016. Os tratamentos constituíram-se em: controle (plantas pulverizadas com água); AVG (125 mg L-1, 30 dias antes da previsão de colheita; DAPC); etefom (120 mg L-1, sete DAPC); AVG parcelado (62,5 mg L-1 + 62,5 mg L-1, 30 e 20 DAPC); AVG parcelado (62,5 mg L-1+ 62,5 mg L-1, 30 e 20 DAPC) + etefom (120 mg L-1, sete DAPC). Frutos de todos os tratamentos foram colhidos na colheita comercial (colheita 1) e após 14 dias (colheita 2). Os frutos foram avaliados após quatro meses de armazenamento refrigerado (0,5 °C±0,2 °C e UR 92±5%). O uso do AVG, independentemente da forma de aplicação, reduziu a taxa de produção de etileno, o amarelecimento da epiderme, a incidência de polpa farinácea e a degenerescência senescente, e manteve maiores valores de firmeza de polpa e de forças para a ruptura da casca e a penetração da polpa. A aplicação de etefom proporcionou frutos com maior incidência de polpa farinácea. Os frutos tratados com AVG, independentemente da forma de aplicação e da combinação com o etefom, apresentam melhor qualidade após o armazenamento refrigerado.Termos para indexação:Malus domestica, reguladores de crescimento, etileno, armazenamento refrigerado.
