Abstract

Metaldehyde is an active substance used for extermination of slugs and snail population. This paper presents the very first case of metaldehyde intentional poisoning of dogs in Serbia. Three-year-old and a six-year-old Swiss white shepard dogs were poisoned. The owner noticed frequent defecation, skeletal muscles spasms and impossibility to put any weight on their back extremities. The vomit of the younger dog was made of green-turquoise colored gut content. Twenty minutes after the onset of the first clinical symptoms dogs died. Macroscopic examination showed congestion of lungs, in the liver and intestines, as well as chemorage in the pancreas, bladder and intestines. Nonspecific pathological lesions were present in the lungs, heart, kidneys, liver, gut, intestines and brain. Pathohistological examination showed dystrophic changes and necrosis in kidneys, brain and intestines. According to anamnestic data, clinical signs, macroscopic and microscopic examination as well as characteristic smell of gut content, one could say that metaldehyde poisoning is the case. Toxicological analysis of gut content samples was performed by using gas chromatography with mass spectrophotometry (GC-MS). Used diagnostic methodology and gut content toxicology results obtained was the base for crime case according to article 269. Republic of Serbia Crime law.

Prema istom izvoru zbog mogućih kratkotrajnih ili dugotrajnih štetnih efekata na životinje, na etiketi ove hemikalije mora da stoji „Pesticid sa ograničenom primenom - Ovaj pesticid može biti fatalan za pse i druge ljubimce ukoliko ga konzumiraju - Držati ljubimce dalje od tretirane zone“ (Anonymous, 1990)
Utvrđivanjem prisustva metaldehida/acetaldehida u sadržaju želuca i digestivnog trakta, kao i u krvi ili urinu potvrđuje se sumnja na trovanje (Wardall i Bailei, 1976; Smith, 1987; Keller i sar., 1991; Jones i Charlton, 1999; Saito i sar., 2008)
