Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Bakgrunden till ämnet vetenskapsteorins införande vid Göteborgs universitet och dess utveckling såsom en del av "forskning om forskning" och senare koppling till vetenskapsstudier (STS) tas upp på basis av en genomgång av skrifter och dokument fram till 1995. Kapitlet innehåller en tabell med 25 nyckelhändelser mellan 1975-1995. Analogin med "drömman om en elefant" anspelar på titeln på en bok red. av J. Bärmark 1984, Forskning om forskning, eller konsten att beskriva en elefant. Framställningen i kapitlet inkluderar ett avsnitt om det antika indiska ämnet "Elefantologi" och antyder att "Forskning om forskning" blev en "vit elefant".

Freemartinism in cattle

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.

Case studies on food safety control of fresh poultry meat: effective control of Salmonella in Sweden

- The starting point was the huge Alvesta outbreak in 1953, which was unprecedented in Sweden, with more than 9000 cases reported. Approximately 4000 persons required hospital care and 90 persons died. The outbreak lasted from June to December 1953, affecting major regions of Sweden. Consequently, several measures were enacted. The Public Health Institute of Sweden created a department of epidemiology to investigate outbreaks; doctors were recommended when seeing patients with diarrhoea to take faecal samples for bacteriological investigations. In 1961, offi cial control of all Salmonella serovars of public health importance on the animal side commenced. Moreover, Salmonella infection in animals became a notifi able disease. One unique feature of the Swedish Salmonella control is the aim to deliver Salmonella - free food to consumers. Therefore, all broilers sent for slaughter should be without Salmonella . This was achieved by the following strategies: (1) preventing contamination of the breeding pyramid (grandparent and parent fl ocks including hatcheries); (2) preventing and eliminating Salmonella contamination in feed given to broiler fl ocks; (3) surveillance of the production chain at critical control points to detect Salmonella contamination; (4) biosecurity on the production site; and (5) whenever Salmonella is found, taking action to remove it from the food chain. The Salmonella control of poultry has been successful, with rare fi ndings of Salmonella in meat and almost no human cases linked to Swedish poultry meat. The baseline studies organized by EFSA (2007 and 2010) found Salmonella in 0% of the broiler fl ocks and 0.3% of the broiler carcasses.

Control, Monitoring and Surveillance of Animal Health and Animal Infectious Diseases at the Slaughterhouse
- 2014

Ingår i: Meat Inspection and Control in the Slaughterhouse. - : Wiley. - 9781118525869 ; :1, s. 249-276

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Meat inspection, meat hygiene and official control tasks in the slaughterhouse have always been of major importance in the meat industry, and are intimately related with animal diseases and animal welfare. The history of meat inspection has largely been a success story. Huge steps have been taken over more than a century to prevent the transmission of pathogenic organisms and contagious diseases from animals to humans. Various factors influence the quality and safety of meat including public health hazards (zoonotic pathogens, chemical substances and veterinary drugs), animal health and welfare issues during transport and slaughter. Meat inspection is one of the most important programs in improving food safety, and its scope has enlarged considerably over the last decades. Globalization has affected the complexity of the modern meat chain and has provided possibilities for food fraud and unfair competition. During the last two decades many food fraud cases have been reported, which have caused concern among consumers and the industry. Subsequently meat inspection is faced with new challenges. Meat Inspection and Control in the Slaughterhouse is an up-to-date reference book that responds to these changes and reflects the continued importance of meat inspection for the food industry. The contributors to this book are all international experts in the areas of meat inspection and the official controls limited to slaughterhouses, providing a rare insight into the international meat trade. This book will be of importance to students, professionals and members of the research community worldwide who aim to improve standards of meat inspection procedures and food safety.
