Situation of laboratories in the UK when accidentally creating a

A laboratory in the UK has accidentally let mice breed too much, in the same amount as a whole city.

According to a recent report by the British Ministry of the Interior, an anonymous laboratory in the United Kingdom accidentally created a huge number of mice - equivalent to the population in York City. In other words, the scientific community accidentally created a "rat city".

Specifically, this laboratory has propagated up to 180,000 mice to do the experiment - larger than the number included in the license, and performed unlicensed experiments on them. Yet, what they received was just a reprimand of the managers.

In fact, mice are the most popular experimental objects.

According to experts, this incident is a warning bell for a similar situation in many laboratories around the UK.

It is known that the laboratory is responsible for the "mouse city" which is only licensed to control about 127,600 mice. However, the actual number reached 179,546, much larger.

Scientists working here say that errors occur when the number of mice is stored in too many different databases. However, another issue in the report needs more attention, which is the fate of the experimental mice.

Accordingly, the post-experimental individuals were left in recovery cages without food or water. Many children die from not eating properly, or suffocating because of a broken vent.

Jan Creamer, president of the National Society of Physiological Anatomy, said: "It's impossible to bring basic care to experimental organisms, and make us question the nature. of those experiments ".

"If we can use more advanced methods without animals, we can eliminate those questions and bring better results."

Mice are being carried out for experiments, but in worrying conditions.

In fact, rats are the most common experimental object, accounting for 60% of the total 2 million animals used by science every year. They are used in research projects for human medicines - including serious diseases such as cancer, diabetes and Alzheimer's.

The reason why rats are used so much is because they are small, but have good adaptability. They also reproduce very quickly, when a mouse mother can produce up to 40 pups each year. At the same time, rats are also genetically closely related to humans.

But of course, animal experiments prevent social activists from watching. PETA (Animal Protection Organization) has called on the government and the scientific community "to stop investing in inhuman experiments with animals" - especially with mice.

Interior Minister Baroness William agrees: "The use of animals plays an important role in the development of science. But to do it, we must keep it all in control, and only use it. use animals when there are no alternatives available. "

"When using animals, we must thoroughly apply 3R - replacement rules, reduction, and refine - while ensuring animal welfare standards. matches should be met ".

"I am committed to maintaining strict regulations on the use of animals in science."
