Abstract : Reduce the use of antimicrobial compounds in livestock production is necessary to limit antimicrobial resistance development and to protect the health of animals, humans and ecosystems. This complex task may only be accomplished via the implementation of a systemic approach, which takes into account the management of animal health as a whole, avoiding simplistic strategies.

No residual test substance was observed after removal of the dressing. The skin irritation potential of 3-hydroxy-1,1-dimethylbutylperoxy-neodecanoate was assessed in a skin irritation test conducted according to the OECD guideline GLP study. A single dose of 0. The test substance was held in contact with the skin for 4 hours by means of a semi-occlusive dressing.
The cutaneous reactions were observed one hour, 24, 48 and 72 hours after removal of the dressing and then daily until day The mean score of the scores recorded after 24, 48 and 72 hours for each animal was calculated.
Having confirmed that the test substance had an irritant effect when administered by cutaneous route, the study began with one animal. Then, the results were confirmed with 2 additional animais. The eyes were not rinsed after instillation of the test substance. The ocular reactions were observed one hour, 24, 48 and 72 hours after the instillation. Slight score of 1 conjonctival chemosis, redness reactions were observed in all animals one hour after instillation.
No ocular reactions remained after 24, 48 and 72 hours. The skin irritation potential of 3-hydroxy-1,1-dimethylbutylperoxy-neodecanoate was assessed in an in vivo skin irritation test conducted according to the OECD guideline Clouzeau, Reversibility of the oedema was recorded on day 7 and erythema was no longer observed on day Between days 7 and 15, desquamation of the skin, signs of superficial reversible damages of the skin were observed in the 3 animals.
Therefore the substance is considered as irritant when administered by cutaneous route in rabbits.

Administrative data Description of key information In an in vivo skin irritation test in rabbits OECD , GLP , 3-hydroxy-1,1-dimethylbutylperoxy-neodecanoate was irritating for skin Clouzeau, c. Reference Endpoint: skin irritation: in vivo Type of information: experimental study Adequacy of study: key study Reliability: 1 reliable without restriction Rationale for reliability incl.
Number of animals: 3 Details on study design: - Area of exposure: right flank, 6 cm2 - Total quantity applied: 0. Irritation parameter: erythema score Basis: animal: 1 and 2 Time point: other: 24, 48 and 72 hours Score: 3 Max. Reference Endpoint: eye irritation: in vivo Type of information: experimental study Adequacy of study: key study Study period: Reliability: 1 reliable without restriction Rationale for reliability incl. The lower and upper eyelids were held together for several seconds to avoid any loss of the test substance.
The right eye, which remained untreated, served as a control. If corneal opacification is difficult to determine, the eye can be examined under a U. Irritation parameter: cornea opacity score Basis: mean Time point: other: 24, 48 and 72 hours Score: 0 Max.
No occular reactions remained after 24, 48 and 72 hours. Interpretation of results: not irritating Remarks: Migrated information Criteria used for interpretation of results: OECD GHS Conclusions: Under the experimental conditions, the substance was not irritating to eyes in rabbits. The eye irritation potential of the substance was assessed in an in vivo test OECD Then, the results were confirmed with 2 additional animals.
Slight score of 1 conjunctival chemosis, redness reactions were observed in all animals one hour after instillation.
