A 2-year-old boy was accidentally poisoned by one spoonful of organophosphate insecticide and presented in cardiac arrest. Spontaneous circulation was restored after initial resuscitation and antidote therapy (atropine and pralidoxime) but the boy finally succumbed with multiple complications. We reviewed the literature on the clinical features and management of acute organophosphate poisoning, and the appropriate protective equipment for preventing secondary poisoning of healthcare workers.

The long-tailed silverfish (Ctenolepisma longicaudata) has recently made its appearance and demonstrated a tremendous proliferation in Norway, where it is currently considered a major indoor nuisance pest in modern buildings. To reduce the risk of human pesticide exposure, several baits with indoxacarb, clothianidin, fipronil or imidacloprid as the active ingredient were investigated to provide knowledge regarding their potential for integrated pest management solutions. Primary and secondary poisoning, as well as the durability of baits, were experimentally evaluated in bioassays. Baits with indoxacarb, clothianidin and fipronil killed more than 90% of the experimental insects (primary poisoning) when presented in competition with food. Only indoxacarb produced high mortality when dead conspecifics were consumed (secondary poisoning) and resulted in more than 75% mortality. The efficacy of baits with indoxacarb against C. longicaudata was also found to be very long. Laboratory degraded baits were consumed and induced high levels of mortality for more than a month, and field degraded baits for more than 6 months. Adults and juveniles were equally affected in the experiments. Primary and secondary toxicity in combination with long durability and effects on both life stages tested suggest that the bait has high-level potential as a safe control strategy against the long-tailed silverfish if indoxacarb is used as the active ingredient.

The use of anticoagulants has increased in recent times as a method for controlling rodent populations. However, this increased use also provokes accidental and intentional ingestion for both animals and humans, triggering poisoning of non-target organisms. In the present report, a clinical case of secondary-poisoning of birds with anticoagulant rodenticides, which took place after a general rodenticide treatment in an Ornithological Zoological Park, is described. Three birds died as a result and samples were submitted to the Veterinary Hospital in Lugo (Galicia, NW Spain). After necropsy, samples of the birds, together with molluscs and faeces, were submitted to the Toxicology Unit of Caceres (Extremadura, W Spain) in order to detect possible chemicals. Results from HPLC analyses revealed the presence of the rodenticides difenacoum and brodifacoum. The present report shows that the risk of secondary exposure resulting from the scavenging of molluscs is likely to be significant. The potential routes of uptake by invertebrates include the consumption of rodent faeces, rodent carcases, the ingestion of soil-bound residues, and the direct consumption of poison baits.

Two different brodifacoum (Talon 20 P™) poisoning regimes effectively killed 100% of resident radio-tagged stoats (Mustela erminea) by secondary poisoning in a New Zealand Nothofagus forest when mice (Mus musculus) were scarce. Resident possums (Trichosurus vulpecula) and ship rats (Rattus rattus) were also killed. The relative importance of different prey species as sources of poison for stoats has not been clearly identified but availability of poisoned prey will determine the efficacy of secondary poisoning in years of low prey abundance. Tracking tunnels did not accurately measure the decline in the stoat population and were probably influenced by immigrant stoats that were kill-trapped and contained high levels of poison. This study corroborates the findings of several other similar studies that secondary poisoning using brodifacoum effectively kills stoats.
