The bar chart below shows consumption of antibiotics by food-producing animals including horses, in 29 European countries (Source: EMA, 2014), as well as New Zealand and Australia in 2014 (Source: R. Condron, IDF Summit Rotterdam, 2016). For Norway, consumption is shown both with and without fish.

In Norway, only 10% of all antibiotics are used for animals, while 90% are used for humans. The low antibiotic use results in a favorable situation when it comes to the presence of resistant bacteria in animal husbandry. The pet industry wants to preserve this situation and prevent the development of resistance, therefore effective measures have been put in place to ensure that the prevalence of antibiotic resistance in the livestock population remains as low as possible.
