Shocking Experiments At HLS Revealed

Posted 22 February 2011

Previously unseen research papers have revealed details of shocking experiments carried out by the animal testing laboratory Huntingdon Life Sciences. The papers, which were sent anonymously to the Stop Huntingdon Animal Cruelty (SHAC) campaign, describe invasive experiments that took place on rats, mice, rabbits and rhesus monkeys between 2001 and 2010.

The substances tested in these experiments include unleaded gas, grape seed extract, Botox, soybean fibre and paraffin wax. SHAC’s report states that all the substances tested had already been tested on animals in previous years, and are all already circulating on the market. Botox testing is particularly controversial, as it is used both clinically and as a cosmetic. Cosmetics testing is illegal in the UK, but laboratories use a loophole in which they can test Botox for clinical use even though it may later be used for cosmetic purposes.

In one experiment, two different species of rats were made to eat paraffin wax for either 30, 60 or 90 days before being killed and dissected. The study concluded that results from this and previous studies cannot be relied upon to evaluate whether paraffin wax is safe for humans due to the large discrepancies between different breeds of rats used. This is not a surprising result, as substances can even affect male and female animals of the same breed differently, and shows once again that results from animal experiments cannot be reliably extrapolated to humans.

Huntingdon Life Sciences was famously exposed by Channel 4 in 1997, when workers were filmed punching beagle puppies in the face. The laboratory has been exposed several times since then, and has been the subject of an intensive campaign of opposition since 1999 when SHAC was formed.
