The Netherlands publishes 2015 animal research statistics

There were 479,580 procedures on animals in the Netherlands for scientific purposes in 2015, down almost 15% from the previous year. This was according to the latest report by the Food and Consumer Product Safety Authority (Nederlandse Voedsel- en Warenautoriteit, NVWA).

There were falls in the number of most species used, with the exception of rats (up by under 0.5%) and other non-mammals (up 62%), of which most of the rise were frogs. Larger falls came from cows (down 56%), chickens (down 40%) and pigs (36%).

Mice, rats, birds and fish are the most commonly used animals, together accounting for over 90% of all procedures – this is similar to previous years and the figures found in many other EU countries. Dogs, cats and primates together account for less than 0.3% of all procedures in the Netherlands.

In 2014 the Netherlands began to produce a set of statistics in accordance with the EU’s method of counting (though they included 2013 figures for comparison). There is a minor difference between how the EU and Netherlands count animal procedures. Primarily in that the Dutch system includes animals killed without a prior procedure (for example, the killing of a mouse for tissue samples that has had no other intervention).

According to the report:

The EU system [is] based on:

The total number of animal studies registered in 2015 (528,159 procedures) minus the number of animals killed without preceding procedure (48,579 procedures) is the number of animal studies for the European registration (479,580 procedures).

We have chosen to use statistics according the EU method of counting for our entire analysis as it makes for an easier comparison with other EU countries. As we can see, both methods tend to reflect the same rises and falls in animal numbers. While the EU counting statistics do not go far back enough to see a trend, we can notice a downwards direction in the Dutch counting methods of number of procedures.

Severity of animal experiments in Holland

2015 was the second year for which the Netherlands has included statistics on the retrospective assessment of severity (i.e. reporting how much an animal actually suffered rather than how much it was predicted to suffer prior to the study). The report showed that 72.2% of procedures were classed as mild (78% in 2014), 19.3% as moderate (17% in 2014), 3.6% as severe (2.7% in 2014), and 4.9% as non-recovery (2% in 2014), where an animal is anaesthetised for surgery, and then not woken up afterwards. As this is the second year of retrospective assessment, the methods used are continuing to be developed (such grimace scales).

Most animals used in the Netherlands were mice.

Here is some other interesting information provided by the annual statistical release.

  • 7%  animals were genetically modified, 95.8% of which were mice.
  • Anaesthesia was not used in 66.5% of procedures because it was unnecessary, it was used in 31.1% of procedures where it was needed, and the remaining 2.37% was procedures where anaesthesia was not applied because it would disrupt the study. They record analgesia separately, that’s 83.9% (not used, not needed) – 9.24% (used) – 6.89% (not used, disruptive
  • The main purpose of research was applied research (29.7%), followed by toxicology testing (28.6%), fundamental scientific research (26.4%), breeding (10.7%) and finally education (4.09%)

The Netherlands publishes their 2014 animal research statistics

The Netherlands Food and Consumer Product Safety Authority (Nederlandse Voedsel- en Warenautoriteit, NVWA) have produced statistics showing the number of procedures carried out on animals in 2014.

The total number of procedures carried out on animals in 2014 was 563,769 procedures, up 25% from 2013.

This year was also the first year where there was retrospective assessment and reporting of severity (i.e. reporting how much an animal actually suffered rather than how much it was predicted to suffer prior to the study). The report showed that 78% of procedures were classed as mild, 17% as moderate, 2.7% as severe, and 2% as non-recovery, where an animal is anaesthetised for surgery, and then not woken up afterwards.

Here is some other interesting information provided by the annual statistical release.

  • The Dutch statistics include animals which have been harvested for organs/tissues/etc, but not otherwise used in a procedure. This accounted for 57,258 animals, of which over 97% were mice, rats or fish.
  • A little over 25% of the animals were genetically modified, most of which were mice.
  • Anaesthesia was not used in 67.3% of procedures because it was unnecessary, it was used in 30.9% of procedures where it was needed, and the remaining 1.9% was procedures where anaesthesia was not applied because it would disrupt the study.
  • The main purpose of research was applied research (32.1%), followed by fundamental scientific research (27.6%), toxicology and safety testing (25.8%), breeding (10.5%) and finally education (3.2%).

It is important to note that this year the Dutch authorities have changed their statistical reporting to fit with new EU regulations. According to the report:

The change of registration methodology is a big adjustment for both the NVWA and the licence holders. The licence holders have adjusted their registration systems or in some cases have even completely replaced them with new systems. The institutes have cleaned up their systems, which made a few licence holders conclude of some animal research dossiers that these data had not been correctly reported in previous years. They have reported these experiments in 2014, which has led to an increase in experiments that were counted in this reporting year. This has resulted in approximately 25,000 extra experiments.

Speaking of Research seek to be the best source of information on the internet on animal research and testing statistics. Unfortunately language barriers mean that we often find it hard to get statistics from non-English speaking countries. If you speak multiple languages and are able to help us out finding the statistics from other countries we would be very grateful. See more here.
