- Background: The traditional meat inspection system is often found to be inefficient. Meat inspection in European countries is in a phase of modernisation to reflect improvements in livestock health and advances in understanding meat safety. The key point of progress is to replace the traditional meat inspection with risk-based meat inspection, including the elements of a meat safety assurance system (MSAS). Scope and approach: Modernisation of meat inspection was launched by the European Food Safety Authority's (EFSA) opinions and recommendations in the period 2011-2013 and consequent amendments to the EU meat inspection legislation in the period 2014-2019. For this study, the EU-funded RIBMINS COST Action conducted a comprehensive survey using an in-depth questionnaire to estimate the level of implementation of new risk-based meat inspection systems in Europe, stakeholders' confidence in the new systems and the main identified obstacles. Key findings and conclusions: The implementation of new meat inspection systems is still ongoing, as they have been fully implemented in just 61%, 42% and 38% of the surveyed countries in the pig, bovine, and poultry sectors, respectively. The main identified obstacles are existing trade agreements with 3rd countries, costs of implementation, inadequate food chain information and resistance from meat inspectors. Improvement of all components of the current meat inspection systems is a prerequisite for further modernisation.

Scientific Opinion on the assessment of studies on the use of carbon dioxide for stunning rabbits
- 2015
-
Ingår i: EFSA Journal. - : Wiley. - 1831-4732. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- The EFSA Panel on Animal Health and Welfare (AHAW Panel) was asked by the European Commission to deliver a scientific opinion on two studies concerned with the use of carbon dioxide for stunning rabbits. The European Commission had received from the Spanish authorities a report of a study entitled ‘Carbon dioxide stunning of rabbits' and another study entitled ‘Stunning of rabbits with carbon dioxide', provided as a complement to the first study. The latter was undertaken in a commercial abattoir where a commercial carbon dioxide stunner was installed. The results of electrocardiography and animal-based measures (nasal discomfort and vocalisation) produced in the experimental slaughterhouse study clearly indicated that the rabbits were subjected to pain and suffering prior to the loss of consciousness. The data presented do not describe stable, controlled or repeatable experimental conditions. The statistical tests used to analyse the data were not appropriate. The study in the commercial abattoir was not based on sound scientific conclusions resulting from the experimental slaughterhouse study. For all of these reasons, the submitted studies did not meet the minimum criteria for eligibility in the EFSA guidance on the assessment criteria for studies evaluating the effectiveness of stunning interventions. Therefore, they were not further assessed.

Scientific Opinion on the scientific assessment of studies on electrical parameters for stunning of small ruminants (ovine and caprine species)
- 2015

Ingår i: EFSA Journal. - : Wiley. - 1831-4732. ; 13

Tidskriftsartikel (refereegranskat)abstract
- The EFSA Panel on Animal Health and Welfare (AHAW Panel) was asked by the European Commission to deliver a scientific opinion on three studies evaluating electrical parameters for the stunning of lambs and kid goats. The Commission received the studies from the Spanish authorities. One study was in the form of a manuscript entitled ‘Electrical stunning effectiveness with current levels lower than 1 A in lambs and kid goats'. The second study consisted of a summary in English entitled ‘Effect of the electrical stunning with inferior intensities of current to 1 Ampere on the carcass quality in Pascuales lambs', and the third study consisted of a summary in English entitled ‘Effect of electrical stunning with inferior intensities to 1 Ampere on the induction to the unconsciousness in lambs'. Reported outcomes for different animal categories were inconsistent and contradictory, indicating a need to validate if the stunning equipment delivered the intended current levels to the animals. The head-only stunning and slaughter intervention failed to achieve and/or maintain unconsciousness during bleeding and the head-to-body stunning and slaughter intervention failed to achieve cardiac ventricular fibrillation in all of the animals, as evidenced by the presence of corneal reflex and rhythmic breathing. No evidence of absence of pain and suffering is presented in the studies. The submitted studies are not considered adequate for a full welfare assessment of the alternative stunning method because they do not fulfil the eligibility criteria and the reporting quality criteria defined in the EFSA guidance on the assessment criteria for studies evaluating the effectiveness of stunning interventions or the EFSA opinion on monitoring welfare at slaughter of small ruminants.

Non-Structural Proteins of Arthropod-Borne Bunyaviruses: Roles and Functions
- 2013
-
Ingår i: Viruses. - : MDPI AG. - 1999-4915. ; 5, s. 2447-2468

Forskningsöversikt (refereegranskat)abstract
- Viruses within the Bunyaviridae family are tri-segmented, negative-stranded RNA viruses. The family includes several emerging and re-emerging viruses of humans, animals and plants, such as Rift Valley fever virus, Crimean-Congo hemorrhagic fever virus, La Crosse virus, Schmallenberg virus and tomato spotted wilt virus. Many bunyaviruses are arthropod-borne, so-called arboviruses. Depending on the genus, bunyaviruses encode, in addition to the RNA-dependent RNA polymerase and the different structural proteins, one or several non-structural proteins. These non-structural proteins are not always essential for virus growth and replication but can play an important role in viral pathogenesis through their interaction with the host innate immune system. In this review, we will summarize current knowledge and understanding of insect-borne bunyavirus non-structural protein function(s) in vertebrate, plant and arthropod.

Freemartinism in cattle
- 2012

Ingår i: Ruminants: Anatomy, behavior and diseases. - 9781620810644 ; , s. 99-120

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Freemartinism is one of the most commonly found intersex conditions in cattle, although it may also occur in small ruminants. The freemartin phenotype appears in a dizygotic twin pregnancy where one twin is a male and the other is a female. Due to precocious anastomoses between the placental vascular systems of the two fetuses, masculinising molecules reach the female twin and disrupt the normal sexual differentiation, whilst in the male the effects of this association are usually minimal. In cattle, this condition is observed in 90 to 97% of twin pregnancies. A freemartin is, by definition, a genetically female fetus masculinised in the presence of a male co-twin, giving rise to a sterile heifer. Genital tract defects with varying severity can be observed in freemartin animals, which often present suppression and disorganization of the ovary, originating a rudimentary or a testis-like gonad depleted of germ cells. The uterine horns may be hypoplastic or instead may be reduced to a cord-like structure suspended in the broad ligament. Anatomic continuity between the uterus and the vagina is frequently absent, and the existence of rudimentary vesicular glands is typical. The external genitalia commonly presents enlarged clitoris, small vulva and a prominent, male-like tuft of hair. As a rule, heifers born twin to a bull have to be considered sterile and should be identified as early as possible to cull them from replacement stock. Despite its limitations, freemartinism is currently diagnosed by physical examination, as karyotyping or blood typing is often considered an unnecessary expense. In cattle, twinning trend has a genetic background that has been associated to hormonal regulation in favor of double ovulations. However, the genetic determinant on the basis of twinning seems to have small importance when compared to environmental or management-associated factors, particularly in dairy cows. In fact, in dairy animals, in particular in high milk producing cows, it has long been proven that the increase of twin calvings occurs due to the hormonal and metabolic disturbances in the energy balance early in the post-partum period. With increased incidence of twin births in cow it is reasonably expectable a small increase in the occurrence of freemartins at the farm levels. In this paper it is the intent to describe the gross and histopathological findings of freemartinism in cattle, using data gathered from a study at an abattoir (17 cases) and from 3 cases diagnosed in living animals, supported by a review of the pathophysiology of the process, and to discuss the available methods for identification of freemartin animals at farm level.

Tidskriftsartikel (refereegranskat)abstract
- Pain treatment of lactating bitches is a clinically relevant, but complicated issue. Published scientific studies regarding the excretion of drugs in canine milk are scarce. When considering the risk of side effects in their offspring, lactating bitches have traditionally received very restricted analgesic and anti-inflammatory therapy. Our aim was to quantify the concentrations of carprofen in milk from lactating bitches and relate those to potential risks for the puppies. A second aim was to evaluate the impact mastitis may have on the concentration of carprofen in milk. A population of 100 bitches was enrolled in the study, among which 88 were bitches treated with carprofen after cesarean section (Group CS), eight were bitches with painful inflammatory conditions (Group I) and four were bitches with mastitis (Group M). The patients enrolled in the study received carprofen 4 mg/kg sc at day 1 followed by 2 mg/kg po every 12 h for the following 2-5 days. Owners were instructed to collect milk once a day for five days. The concentration of carprofen in the milk was quantified with ultra-performance liquid chromatography-tandem mass spectrometry. The data obtained were statistically analyzed as repeated-measures data with a mixed-model approach. Data were used to calculate the theoretical maximum total daily intake of carprofen by the puppies in order to perform a computerized simulation of the plasma concentration of carprofen in the puppies. Follow-up telephone interviews to check the status of the enrolled bitches and their litters occurred at one week and three-six months after treatment with car-profen. The major finding of the study was that the concentration of carprofen in the milk was <700 ng/ mL from bitches undergoing CS or suffering painful conditions other than mastitis. In comparison, administration of 2 mg/kg of carprofen sc or po to adult dogs, results in mean maximal plasma con-centrations of 19480 +/- 5420 ng/mL (mean +/- SD). Moreover, data suggests that inflammation of the mammary gland results in a higher concentration of carprofen in milk (up to 1300 ng/mL). In the computerized simulation, the plasma concentrations of carprofen in puppies in group CS and in group I are one tenth of the concentration in adult dogs receiving carprofen at standard doses. Considering the low excretion into milk, carprofen provides an analgesic alternative to lactating bitches without mastitis.(c) 2022 Published by Elsevier Inc.
