Halal certification in Europe bodies. According to the Halal Food Authority (HFA) in the UK, poultry (chickens, turkeys and ducks) can only be "immobilised" prior to slaughter using electric water baths, while ovine animals (lamb, sheep and goat) can only be stunned using electric tongs. The majority of bovine animals (cattle, bull, cow and ox) in the UK are stunned with a captive-bolt pistol, but this is not permitted by the HFA because of the risk that it may kill the animal. The second position, which emerges from a derogation of the above legislation, allows EU member states to grant slaughterhouses that supply Muslim
Alternatives to animal testing test dummies, complete with internal sensors and video, have replaced live animal trauma testing for automobile crash testing. The first of these was "Sierra Sam" built in 1949 by Alderson Research Labs (ARL) Sierra Engineering. These dummies continue to be refined. Prior to this, live pigs were used as test subjects for crash testing. Computer models have been constructed to model human metabolism, to study plaque build-up and cardiovascular risk, and to evaluate toxicity of drugs, tasks for which animals are also used. In 2007, US researchers using the world's fastest computer at the time, BlueGene L, modeled half a
