Monkeys are strapped into metal harnesses, while cats and dogs are left bleeding and dying in footage which animal rights activists claim was filmed at a German toxicology laboratory.
The German animal activist organisation Soko Tierschutz together with Cruelty Free International say the alleged abuse took place at LPT Laboratory of Pharmacology and Toxicology in Mienenbuttel, on the outskirts of Hamburg.
Photos show macaques strapped to metal brackets in rows on the wall, others have their heads in restraints and are shown desperately trying to escape, while a beagle appears to bleed profusely in cramped cells.
An undercover activist got a job at the research facility from December 2018 to March 2019, and says he witnessed testing on beagles, monkeys, cats and rabbits, carried out for companies throughout the world.

The undercover worker said the animals were kept in horrific conditions.
Beagles reportedly had pipes forced down their throats and were given capsules, and left suffering and often bleeding following the experiments.

He claimed the animals were treated with violence by the workers, who are not trained animal carers.
Friedrich Mullen from Soko Tierschutz said: ‘The animals were even still waggling their tails when they were being taken to be killed, the dogs were desperate for human contact.’
He added: ‘The worst treatment was kept for the monkeys. The macaques breed of monkeys are small, relatively light primates, which are often used for animal experiments at LPT.
‘They are kept in cramped conditions in small cages. Many of the animals have developed compulsive tendencies and are seen going round in circles.’
The cats are said to be given up to 13 injections per day by untrained professionals and left to suffer.
The animal activists have reported the case to police who are investigating.
They also claim the laws in Germany protecting animals from experiments are not strict enough and call for the laws to be tightened.

LPT is a family-owned contract-testing laboratory carrying out toxicity testing for pharmaceutical, industrial and agro-chemical companies from all over the world in order to meet the requirements of governments and regulatory authorities.
According to the organisation Cruelty Free International: ‘Toxicity testing involves poisoning animals to see how much of a chemical or drug it takes to cause serious harm, in an attempt to measure what a “safe” dose for humans might be.
‘Animals are injected with or made to eat or inhale increasing amounts of a substance to measure the toxic effects which can be severe and include vomiting, internal bleeding, respiratory distress, fever, weight loss, lethargy, skin problems, organ failure and even death. No anaesthetics or pain relief are provided.’

Michelle Thew, Chief Executive of Cruelty Free International stated: ‘Our investigation has uncovered appalling animal suffering, inadequate care, poor practices and breaches of European and German law.
‘We are calling for the Laboratory of Pharmacology and Toxicology (LPT) to be closed. We are also calling for a comprehensive review into the use of animals in regulatory toxicity testing in Europe, including the UK.
‘Every investigation, without fail, shows a similar tale of misery and disregard of the law.’
