Consumer Affairs Minister Renate Künast opened the 5th International Congress on Alternatives to Animal Experimentation in Berlin on Monday, where some 850 experts are set to discuss the way forward.
Legislation protects lab animals from cruelty or mistreatment
"We have to ask ourselves in what ways animal experimentation is really necessary to making our lives safer," said Künast at the opening of the congress. Presenting the case for greater investment in alternatives, she said that Germany was still a long way off the Green party's target of being Europe's leader in developing animal-free testing methods.
"The number of experiments conducted on animals in 2003 is slightly lower than in 2001," Künast said. "But the figures are still too high."
In an interview with the daily Der Tagesspiegel, the minister said she even expected the number to rise once the EU's new directive REACH (Registration, Evaluation and Authorisation of Chemicals) is implemented. Its proposals regulate the use of some 30,000 toxic synthetic chemicals in everyday manufactured objects, largely based on animal testing strategies.
But Künast conceded the issue was a complex one.
"There is a conflict of interests," she said. "Efforts to protect our health and environment cannot be wholly exempt from animal experimentation."
The scientists at the Berlin congress will be examining efforts made by industry to replace animal experimentation in obligatory toxicity tests. Proposed alternatives include applications of modern bio-technology that allow, for example, scientists to simulate human skin and thereby test potentially adverse reactions without resorting to the use of animals.
Another field heavily dependent on animal testing is pain research, with almost every medical treatment available first tested on animals. Animals are also used to develop anaesthetics to prevent pain during surgery.
Speaking in Berlin on Monday, Künast singled out the cosmetics industry as exemplary in its development of alternative methods of product testing, while Horst Spielmann, director of the Central Office for Collecting and Assessing Altrnatives to Animal Experimentation (ZEBET), said progress has definitely been made.
"Using animals in teaching curricula is already superfluous," he told German broadcaster ARD. "In many countries, one can become a doctor, vet or biologist without ever having performed an experiment on an animal."
German household-scale battery maker Sonnenbatterie will soon enable buyers of its systems to trade energy with each other over the grid. It'll save clients money, and it's another step toward a clean energy future.

Germany's vehicle safety regulator KBA has accepted Volkswagen's proposed repairs for its emissions-cheating EA189 diesel engines in Europe, allowing the carmaker to apply an inexpensive refit to lower emissions.
