We present an annotated bibliography of peer reviewed scientific research highlighting the human health, animal welfare, and environmental risks associated with genetic modification. Risks associated with the expression of the transgenic material include concerns over resistance and non-target effects of crops expressing Bt toxins, consequences of herbicide use associated with genetically modified herbicide-tolerant plants, and transfer of gene expression from genetically modified crops through vertical and horizontal gene transfer. These risks are not connected to the technique of genetic modification as (...) such, but would be present for any conventionally produced crops with the same heritable traits. In contrast, other risks are a direct consequence of the method used in gene manipulation. These come about because of the unstable nature of the transgene and vectors used to insert it, and because of unpredictable interactions between the transgene and the host genome. The debate over the release of genetically modified organisms is not merely a scientific one; it encompasses economics, law, ethics, and policy. Any discussion on these levels does, however, need to be informed by sound science. We hope that the scientific references provided here will provide a useful starting point for further debate.

In common with much of theEnglish-speaking world, New Zealandersgenerally oppose the use of animalexperimentation where there is no demonstrableand immediate benefit for human, animal, orenvironmental health. Intrusive experiments onsheep internal and external parasites publishedbetween 1996 and 2000 are reviewed, anddiscussed in relation to these publicsensibilities. A total of 16 publishedexperiments on sheep parasites involvedsurgical manipulations or other intrusiveprocedures. Some of these experiments had noshort-term application, or the only applicationwas in increasing animal production. Otherscould have been modified at some extra expenseso (...) that they were less intrusive. Still otherswere duplications of previous work. All thesemanipulations would be unacceptable accordingto the orthodox morality of the general public.Breeding programs, rotation of grazing,``low-tech'' vaccination, and in vitromodels of sheep can provide insights intopreventing parasite infestation withoutintrusive experiments. Such research protocolsshould take priority over existing programs.The results also confirm earlier reports thatanimal ethics committees are not fulfillingtheir mandated objective of acting as watchdogsfor the public. Possible changes in New Zealandanimal welfare legislation and itsinterpretation by Animal Ethics Committees arediscussed. (shrink)

Pest control operations andexperimentation on sentient animals such as thebrushtail possum can cause unnecessary andavoidable suffering in the animal subjects.Minimizing animal suffering is an animalwelfare goal and can be used as a guide in thedesign and execution of animal experimentationand pest control operations.The public has little sympathy for the possum,which can cause widespread environmentaldamage, but does believe that control should beas painless as possible. Trapping and poisoningprovide only short-term solutions to the possumproblem and often involve methods that causesuffering. Intrusive experiments (...) connected withthese methods of control and published in thelast 6 years are reviewed. Many of theexperiments do not attain the welfare standardsrequired by members of the public. (shrink)

Fly strike is a painful conditioncaused by live maggots eating at the flesh of sheep.Remedies for this disorder are traumatic, with sheepundergoing painful mulesing and tail dockingoperations to protect against flystrike. In an attemptto find control solutions and to understand thedisorder, Australasian researchers increase sheepsuffering by conducting experiments that artificiallyinduce fly strike. Some of these experiments have noapplication in prevention and control of fly strike.Many others could be modified or replaced with lesspainful techniques.Anecdotal evidence through communication withorganic farmers suggests that (...) fly strike is largelypreventable if farmers keep sheep healthy and inspectthem regularly. Some organic farmers have largelyeliminated fly strike from their farm. Investigationson fly strike control using non-intrusive techniquesare also progressing in Australasia and the UnitedKingdom.
