Excessive use of antibiotics can result in antibiotic resistance in some areas, a major risk factor for health and for fighting diseases, particularly for humans.
In general, food production from animals require the use of medicines to treat diseases, not least with a view to animal welfare. If not controlled, the use of antibiotics and other medicines in conventional fish farms could contribute to an undesired and negative affect on humans and the environment.
Our ambitions in this area
Lerøy aims to avoid unnecessary use of antimicrobial agents and other medicines. The use of antimicrobial agents is seen as a last line of defence and only applied in situations where deemed necessary to protect fish welfare, and when factors relating to food safety, the environment, resistance and effect have been clarified. Lerøy emphasises the importance of a preventive operating practice, aiming to reduce the number of incidences of disease, thereby reducing the need to medicate fish.
How we work in the area
All medicines used must be prescribed by authorised fish health personnel. Before starting medication, a risk analysis is carried out to assess measures not involving medicines, and the impact on any vulnerable habitats and species close to the facility.
How we measure our impact
All use of medicines is logged in our own production management system. Details such as the name of the person who prescribed the medicine, approved assistant, active substances, quantity, treatment period and retention period for the fish are all registered each time treatment is administered.
Environmental surveys are conducted at least once a year in the zone surrounding each facility. These surveys are conducted by an independent company. The analyses are in three parts: fauna, chemical and sensory. The analyses result in a score from 1 to 4, where 1 is the best result. If the score is 3 or 4, action must be taken to improve conditions at the facility. Similar and more extensive surveys are conducted outside the immediate surroundings at least every five years.
Targets per KPI and Results per KPI
Target 2021: Annual use of antibiotics in the Group: 0 kg
Result 2021: 0 kg
Result 2020: 18,99 kg One treatment with 18.99 kilo total, which is 0,08mg Florfenikol/kg produced fish.
This was treatment administered to small, newly released fish, for a bacterial infection, Tenacibaculum sp. and Moritella viscosa.
Result 2019: 0 kg
Target 2022: Zero use of antibiotics
Action taken due to results per KPI
Lerøy avoids unnecessary use of antimicrobial agents. To achieve this, a number of different preventive measures are implemented and are part of a preventive operating practice including vaccination, risk management, disease control, structural measures, early diagnoses etc. A number of preventive projects have been initiated to prevent future use of antibiotics. These include:
