But the hunt for substitutes continues, and last weekend the Middle European Society for Alternative Methods to Animal Testing met in Linz, Austria, to review progress.A good place to start finding alternatives for toxicity tests is the liver the organ responsible for breaking toxic chemicals down into safer molecules that can then be excreted.
It is toxic to the stomach lining, and it is this toxicity that provokes the ulcers and cancers for which H. pylori is notorious.The obvious medical temptation and, indeed, what has happened in practice is to annihilate the bacterium with antibiotics.

The number of animals used for toxicity testing in Europe will thus, experts reckon, quintuple from just over 1m a year to about 5m, unless they are saved by some dramatic advances in non-animal testing technology.
