“…Based on laboratory experiments, HPAI viruses do not persist in the environment as long as LPAI viruses [ 122 ]. Conversely, HPAI viruses were found to persist longer than LPAI viruses in poultry litter material [ 123 , 124 ]. Thus, virus persistence in the environment is likely to vary among different H5 lineages and habitats and affects the likelihood of virus maintenance within and among wild bird and domestic bird populations.…”

Highly pathogenic avian influenza (HPAI) outbreaks in wild birds and poultry are no longer a rare phenomenon in Europe. In the past 15 years, HPAI outbreaks—in particular those caused by H5 viruses derived from the A/Goose/Guangdong/1/1996 lineage that emerged in southeast Asia in 1996—have been occuring with increasing frequency in Europe. Between 2005 and 2020, at least ten HPAI H5 incursions were identified in Europe resulting in mass mortalities among poultry and wild birds. Until 2009, the HPAI H5 virus outbreaks in Europe were caused by HPAI H5N1 clade 2.2 viruses, while from 2014 onwards HPAI H5 clade 2.3.4.4 viruses dominated outbreaks, with abundant genetic reassortments yielding subtypes H5N1, H5N2, H5N3, H5N4, H5N5, H5N6 and H5N8. The majority of HPAI H5 virus detections in wild and domestic birds within Europe coincide with southwest/westward fall migration and large local waterbird aggregations during wintering. In this review we provide an overview of HPAI H5 virus epidemiology, ecology and evolution at the interface between poultry and wild birds based on 15 years of avian influenza virus surveillance in Europe, and assess future directions for HPAI virus research and surveillance, including the integration of whole genome sequencing, host identification and avian ecology into risk-based surveillance and analyses.

“…Dentro del estudio de los diferentes tipos de cama se evidenció una marcada significancia del residuo de caña frente a los demás tipos de cama analizados; lo cual generó que los animales presenten una mayor temperatura frente a los diferentes grupos, lo cual se asume al grado de humedad más alto que posee el residuo de caña que sumado al calor ambiental genera que la humedad relativa aumente, causando la elevación corporal de la temperatura. De similar forma un estudio realizado por Figueroa et al (2021); (Toscano Miranda et al, 2021) evidencian las propiedades del residuo de caña en la generación de calor cuando se encuentra en grandes cantidades. En estudios previos, se comprobó que este tipo de residuo industrial puede favorecer el crecimiento de agentes microbianos (Crippen et al, 2021;Mthiyane et al, 2001), lo cual sumado al estrés de los animales en el momento del transporte favorece para la aparición del complejo respiratorio bovino (Timsit et al, 2017;Timsit et al, 2018).…”

La presente investigación tuvo como objetivo dilucidar los factores relacionados al transporte que tienen influencia sobre el pH y la temperatura del músculo post mortem, en la canal de los animales faenados en el camal frigorífico Nobol (GAI) de la provincia del Guayas, Ecuador. Se muestrearon 605 bovinos; las variables independientes como mezcla de categorías, tipos de categorías, sexo, tiempo de viaje y tipo de cama usado para el transporte fueron evaluados como posibles causas de variaciones del pH y temperatura. Se identificó que la temperatura de los bovinos sometidos a más de 3 horas de viaje y camas a base de residuo de caña generan una elevación de la temperatura corporal, afectando en la calidad de la carne y produciendo carnes de tipo pálidas, blandas y exudativas (PSE); corroborando que los factores relacionados al transporte son precursores de estrés en los semovientes.

“…In many instances, however, pathogens such as E. coli O157:H7, Salmonella spp., and L. monocytogenes were present in composted organic waste [29][30][31][32][33] and animal-waste amended soil [34]. One possible reason for this could be that the composting process did not attain a high enough temperature for a sufficient duration [35,36]. In addition to this, cross contaminations are also known to cause pathogen contamination in cross products [37,38].…”

Assessment Impacts of Ozone on Salmonella Typhimurium and Escherichia coli O157:H7 in Liquid Dairy Waste

et al. 2022

Liquid dairy manure, which is produced in enormous quantities in flush dairy manure management systems, is commonly used as an alternative to chemical fertilizers. It provides nutrient benefits to crops and soils. While dairy waste is a well-accepted and widely used fertilizer, the presence of indicator organisms and human pathogens in manure may lead to pathogen contamination in crops and soils. This study is focused on the examination of ozone gas-based sterilization. In the past, ozone (O3) has been used for sanitizing various foods and solid surfaces, but the potential of O3 for eliminating human pathogens in liquid dairy waste is not studied yet. Pathogens such as Salmonella Typhimurium and Escherichia coli O157:H7 are reported to be present in liquid dairy manure, and this research evaluated the effects of various levels of ozone on the survival of these two pathogens. We designed a continuous type O3 treatment system that has four major components: (1) ozone generator using oxygen; (2) ozone concentration control by mixing with pure air; (3) continuous monitoring of ozone concentrations; and (4) ozone experiment chambers. Various levels of ozone (43.26, 87.40, and 132.46 mg·L−1) were produced in the ozone system, and subsequently, ozone was diffused through liquid manure. Liquid manure was exposed to ozone for multiple durations (30, 60, and 120 min). To determine the effectiveness of O3 in eliminating pathogens, time-series samples were collected and analyzed for determining the levels of S. typhimurium and E. coli O157:H7. Preliminary results showed that ozone concentrations of 132.46 mg/L, and exposure time of 120 min resulted in the reduced levels of E. coli and Salmonella. Low levels of ozone and limited exposure time were found to be less effective in pathogen removal potentially due to high solid contents. Additional studies carrying out experiments to evaluate the impacts of solids in combination with ozone concentrations will provide further insights into developing full-scale ozone-based treatment systems.
