The sylvatic Trichinella cycle and its implications for Trichinella control in Germany

Trichinellosis is a food-borne, zoonotic disease caused by a parasitic organism. Pork containing muscle larvae represents the most important source of human trichinellosis. In Germany, each slaughtered domestic swine is systematically sampled and examined for Trichinella spp. European Union legislation (EC (No.) 2075/2005) condones the approach of a risk-oriented meat inspection for Trichinella in pigs which is accompanied by monitoring programmes for pig holdings and reservoir animals. Here we discuss the current epidemiological situation of Trichinella in the sylvatic cycle in Germany and the implications for the implementation of risk-based sampling.     

Molecular diagnostics for the food animal practitioner.

Molecular diagnostics are becoming widely used as routine diagnostic tests performed by food animal practitioners. This article discusses the variations of several commonly performed molecular assays with regard to their molecular basis and the appropriate interpretation of the results. Applications of these methods are discussed in the context of infectious disease testing and genetic testing of food animal species.     

Veterinarians and food safety

Since the early days of veterinary science, vets have played an important part in protecting public health through controls over the safety of food of animal origin. Traditionally, public health has been treated as a topic separate from the mainstream veterinary subjects of diagnosis and treatment of animal disease. However, there is now increasing awareness of the interconnection between animal and human health, and between the work of vets in production animal practice and those in food safety and other disciplines, as Kenneth Clarke explains.

Pet food safety: dietary protein

The goal of this article was to review the evidence surrounding the risks posed by insufficient or excessive dietary protein. Dietary protein is required to provide essential amino acids and replenish protein reserves. When intake is deficient, protein turnover slows and lean body mass is gradually depleted. These changes lead to increased morbidity and mortality. Dogs can maintain nitrogen balance (typically used to define minimum requirements in adults), yet be in a protein-depleted state due to physiologic adaptations. Preservation of protein turnover and lean body mass requires about threefold more protein than nitrogen balance. The ability of excess dietary protein to induce renal pathology was studied in both dogs with chronic kidney failure and older dogs without kidney failure. Numerous studies have confirmed that protein does not adversely affect the kidneys. However, phosphorus- and protein-restricted diets are clinically beneficial in dogs with existing chronic kidney failure. Protein restriction for healthy older dogs is not only unnecessary, it can be detrimental. Protein requirements actually increase by about 50% in older dogs, while their energy requirements tend to decrease. When insufficient protein is provided, it can aggravate the age-associated loss of lean body mass and may contribute to earlier mortality. Older dogs should receive at least 25% of their calories from protein, typically provided by diets containing at least 7 g protein/100 Kcal ME.     

借食品安全之名行贸易保护之实--日本高筑农业贸易壁垒我国农产品对日出口前景堪忧

近年来,日本借口存在食品安全问题不开放农产品市场,相继出台了一系列保护措施。这些措施名义上是为了食品安全,实质上是借食品安全之名行贸易保护之实——高筑农业贸易壁垒。这在国际上是一致公认的,如2002年5月,日本前农水相官员访问欧洲与世贸组织总干事穆尔会谈时,穆尔就敦促日本开放农产品市场,日     

Consumer expectations for livestock farming and food safety

Food safety optimization measures neglect the consumers' psychological requirements. To avoid guilt--delight-discords, problems of livestock farming are not registered in the first place. Food checks at the purchase are felt to be a matter of the consumer's own competence, using his five senses and primarily seen as a tasting test. Market mechanisms supply additional safety in the background. Consumer behavior in acute crises must be seen from the point of protective magie. Governmental pre-tests raise doubts on the consumer's shopping competence, they are felt to be insulting and unreliable. Certificates and quality seals only stand a chance as complimentary service to the consumer's own competence.     

ASAS Centennial Paper: Developments and future outlook for preharvest food safety

The last century of food animal agriculture is a remarkable triumph of scientific research. Knowledge derived through research has resulted in the development and use of new technologies that have increased the efficiency of food production and created a huge animal production and food manufacturing industry capable of feeding the US population while also providing significant quantities of high-quality food for export to other countries. Although the US food supply is among the safest in the world, the US Center for Disease Prevention and Control estimates that 76 million people get sick, more than 300,000 are hospitalized, and 5,000 die each year from foodborne illness. Consequently, preventing foodborne illness and death remains a major public health concern. Challenges to providing a safe, abundant, and nutritious food supply are complex because all aspects of food production, from farm to fork, must be considered. Given the national and international demand and expectations for food safety as well as the formidable challenges of producing and maintaining a safe food supply, food safety research and educational programs have taken on a new urgency. Remarkable progress has been made during the last century. Wisdom from a century of animal agriculture research now includes the realization that on-farm pathogens are intricately associated with animal health and well-being, the production of high-quality food, and profitability. In this review, some of the developments that have occurred over the last few decades are summarized, including types, sources, and concentrations of disease-causing pathogens encountered in food-producing animal environments and their association with food safety; current and future methods to control or reduce foodborne pathogens on the farm; and present and future preharvest food safety research directions. Future scientific breakthroughs will no doubt have a profound impact on animal agriculture and the production of high-quality food, but we will also be faced with moral, ethical, and societal dilemmas that must be reconciled. A strong, science-based approach that addresses all the complex issues involved in continuing to improve food safety and public health is necessary to prevent foodborne illnesses. Not only must research be conducted to solve complex food safety issues, but results of that research must also be communicated effectively to producers and consumers.     

Epidemiology of Trichinella infection in the horse: the risk from animal product feeding practices

A discovery in 2002 of a Trichinella spiralis-infected horse in Serbia offered an opportunity to conduct needed epidemiological studies on how horses, considered herbivores, acquire a meat-borne parasite. This enigma has persisted since the first human outbreaks from infected horse meat occurred in then 1970s. The trace back of the infected horse to a farm owner was carried out. Interviews and investigations on the farm led to the conclusion that the owner had fed the horse food waste in order to condition the horse prior to sale. Further investigations were then carried out to determine the frequency of such practices among horse owners. Based on interviews of horse producers at local horse markets, it was revealed that the feeding of animal products to horses was a common practice. Further, it was alleged that many horses, particularly those in poor nutritional condition would readily consume meat. A subsequent series of trials involving the experimental feeding of 219 horses demonstrated that 32% would consume meat patties. To confirm that horses would eat infected meat under normal farm conditions, three horses were offered infected ground pork balls containing 1100 larvae. All three became infected, and at necropsy at 32 weeks later, were still positive by indirect IFA testing, but not by ELISA using an excretory-secretory (ES) antigen. This result indicates that further study is needed on the nature of the antigen(s) used for potential serological monitoring and surveillance of horse trichinellosis, especially the importance of antigenic diversity. The experimentally-infected horses also had very low infection levels (larvae per gram of muscle) at 32 weeks of infection, and although the public health consequences are unknown, the question of whether current recommended inspection procedures based on pepsin digestion of selected muscle samples require sufficient quantities of muscle should be addressed. It is concluded that horses are more willing to consume meat than realized and that the intentional feeding of animal products and kitchen waste is a common occurrence among horse owners in Serbia (and elsewhere?). This is a high risk practice which demands closer scrutiny by veterinary and food safety authorities, including the implementation of rules and procedures to ensure that such feeds are rendered safe for horses, as is now required for feeding to swine.
