Life Saving Animal Research at HLS



We have many examples of pointless experiments carried out at HLS, but the ones we feature here are amongst the most striking. Remember every drug or product that is withdrawn because of serious side effects, every pesticide that proves to be carcinogenic, every stupid 'new and improved' household product that we don't need, Huntingdon will have forced that product down the throats of thousands of animals and then passed it safe just for it later to go on to maim, harm and kill humans.


In 2009, a Japanese company paid HLS to use and kill 4-week-old rats in a study to test the effects of suguki (a traditional, fermented Japenese vegetable) on the body of humans. This is despite the vegetable having been consumed safely by the Japanese population for well over 1,000 years - something they point out in their own research paper!

The rats were force fed a strain of the vegetable by 'oral gavage' - the scientific way of saying a tube was forced down the animals' throat and the substance pumped directly into their stomachs. Later, the rats were killed and dissected to see what effect it had on the body. Naturally, and unsurprisingly, there was "no clear treatment-related effect and no significant toxicological effect" from the vegetable.

"The strain was isolated from a Japanese traditional fermented vegetable (suguki) that has been consumed for over 1000 years. Because of this history, L. brevis can be considered generally safe.”

Yet despite its obvious safety, HLS felt the need to kill animals to test it anyway, of course finding it "safe for consumption in humans". As a Contract Research Organization (CRO), this is one of the many examples available that demonstrate how HLS will literally test anything - and everything - on animals if they are paid to do it!


HLS conducted yet another ‘life saving’ experiment in 2004 on pregnant rats; this time, testing the chemical n-Propyl bromide. What HLS fail to mention in their experiments is that this chemical is a “solvent used for the cleaning of metal surfaces, removal of soldering residues from electronic circuit boards, and as an adhesive solvent”.

This chemical has been under dispute for many years and a vast array of experiments have already been conducted on rats in an attempt to establish whether it has an effect upon the health of adult humans and unborn babies.

During this experiment, HLS forced pregnant and lactating female rats to inhale the chemical in varying doses by placing them in tube-shaped inhalation devices not much bigger than their bodies. This was not only to see the effect on the mother rats but the unborn and already weaning babies. The rats, numbering over 50 adult females and numerous babies, were forced to inhale this substance for a total of 31 days. Once the experiment was completed, the rats were all killed and dissected to have their internal organs weighed and examined.

This chemical has been in use for many years, with large amounts of workers having already been exposed to it. Debate still remains in both scientific and industry arenas over the safe level of exposure; while one paper clearly shows that rats have fertility problems when exposed to the chemical, others prove it to be entirely safe.
In effect, groups and health protection bodies are arguing over which toxicity category to place the chemical, pointing out continuously that there is “insufficient evidence”.

Finally, the Health and Safety Executive of the UK (UK HSE) sum up this problem by pointing out: “ is not possible to judge which studies provide the most relevant model for humans.”
