Evaluation of infrared thermography, force platform and filmed locomotion score as non-invasive diagnostic methods for acute laminitis in zebu cattle.

This study aimed to characterize oligofructose-induced laminitis in zebu cattle and comparatively evaluate four different diagnostic methods for laminitis. A total of 29 rumen-cannulated Nelore heifers, weighing 474.5 ± 58.5 kg were used. Laminitis was experimentally induced by intraruminal administration of 0.765 g/kg oligofructose twice daily for three consecutive days, followed by a single dose of 10.71 g/kg oligofructose on the fourth day. The animals were evaluated before administration of the highest dose of oligofructose (basal) and every six hours for up to 24 hours (6, 12, 18, 24 hours) and thereafter, every 12 hours for up to 72 hours (36, 48, 60, 72 hours) post-induction. The following diagnostic methods were used: hoof pain sensitivity test (hoof-testing), locomotion scoring, hoof infrared thermography, and force platform. Diagnosis of laminitis was confirmed after two positive responses to hoof pressure testing. Using a receiver operator characteristic (ROC) curve, we defined the appropriate cut-off for infrared thermography and force plate as 30 °C and < 24%, respectively. From the 29 heifers, 27 developed laminitis (93.1%) which occurred between 24 h to 72 h in the digits from two limbs, with more frequent sensitivity in the lateral digits. Locomotion analysis detected twenty-eight heifers with laminitis and showed that a greater (P = 0.006) number of animals had lameness in two limbs (n = 13; 56%). Using hoof-testing as gold standard for the diagnosis of laminitis the locomotion score displayed 100% sensitivity, 97% specificity and 98% accuracy; infrared thermography showed 96% sensitivity, 63% specificity, and 75% accuracy whilst force plate had 76% sensitivity, 82% specificity and 79% accuracy. This suggests that, for the diagnosis of laminitis in cattle, pain evaluation is more efficient. Considering the difficult to evaluate pain sensitivity in Nelore animals, filmed locomotion score, infrared thermography and force plate methods can be indicated for non-invasive lameness detection in beef farms.

Avaliação das condições higiênico-sanitárias no açougue de um hipermercado em um município da Baixada Santista / Evaluation of hygienic-sanitary conditions in the butcher of a hypermarket in a municipality of Baixada Santista

As boas práticas nos serviços de alimentação são imprescindíveis para a garantia de qualidade e segurança dos alimentos. Objetivou-se nesta pesquisa avaliar as condições higiênico-sanitárias de um açougue em hipermercado no município de Guarujá-SP. O estudo de caráter observacional foi realizado in loco, e teve como ferramenta de pesquisa o check-list baseado nas portarias RDC 275/2002 e RDC 216/2004 da ANVISA, e logo após a avaliação foi coletado dez amostras dos principais pontos críticos do setor para análise microbiológica. Observou-se no estabelecimento que, mesmo atendendo uma grande porcentagem de conformidades em relação às boas práticas, foram detectadas dez amostras positivas para diversas bactérias Gram – e Gram +, o que pode representar risco eminente à segurança dos alimentos.

Good practices in food services are essential for quality assurance and food safety. The objective of this research was to evaluate the hygienic-sanitary conditions of a butcher shop in a hypermarket in Guarujá-SP. The observational study was carried out on site, and had as research tool the checklist based on ANVISA RDC 275/2002 and RDC 216/2004, and shortly after the evaluation was collected ten samples of the main critical points of the sector. for microbiological analysis. It was observed that even meeting a high percentage of compliance with good practices, the establishment presented the ten positive samples for several gram – and gram + bacteria which may represent an imminent risk to food safety.
