Nodular Gill Disease (NGD) is an emerging pathogenic condition that causes gill damage and mainly affects farmed freshwater fish, rainbow trout (Oncorhynchus mykiss) in particular, and this inevitably generates noticeable economic losses for the industry. The present study aimed to assess the prevalence of NGD in the Autonomous Province of Trento, a highly productive area located in Northeastern Italy, traditionally suited to rainbow trout production, and to identify possible risk factors for the introduction of this disease in trout farms. The necessary data were obtained through a questionnaire and the collection of fish samples.

Carbamate pesticides (CBs) are reported as one of the main causes of intentional or accidental poisoning of animals. Anticoagulant rodenticides (ARs) form the main class of poisons implicated in analyzed poisoned baits. These two groups of pesticide compounds include multiple substances, and thus, the development of a simple and rapid multiclass/multiresidue analytical method for simultaneous identification of both toxicant classes should be a useful strategy for analytical laboratories to reduce analysis time and cost.

Article Synopsis
  • Infectious pancreatic necrosis virus (IPNV) is a double-stranded RNA virus that originated in Italian trout farms in the late 1970s and has since become endemic in the region.
  • Analysis of 75 IPNV strains from 1978 to 2017 showed low genetic variation and identified four genetic clusters, indicating strong selective constraints compared to other RNA viruses affecting salmonids.
  • The study suggests that the low virulence of Italian IPNV, characterized by specific genetic markers, may lead to reduced virus replication and slow evolutionary change, providing insights into the virus's evolution in nature.

Article Synopsis
  • Fish kills can evoke strong public concern, often linked to suspicions of pollution, but many incidents arise from natural causes like low dissolved oxygen levels; however, the specific reasons can sometimes remain unclear.
  • In a case from Padua Province, Italy, a fish kill event was traced to high levels of pyrethroids, a type of pesticide, found in water samples from an industrial area after a stormwater drain overflow.
  • This case adds valuable data on fish kills related to pesticide exposure and underscores the need for standardized fish kill management protocols to improve investigation and reporting efforts by various institutions.

In the present paper we analyze and discuss about the records referring to animal poisonings and poisoned baits cases covering the period between 2007 and 2013 and submitted for diagnostic investigations to the Istituto Zooprofilattico Sperimentale delle Venezie (IZSVe), which is the public veterinary health institute competent for the north eastern Italian regions. All data were gathered by a passive surveillance system based on voluntary reporting, which became mandatory in 2009 after a decree of the Italian Ministry of Health had come into force. This prohibited the use and detention of poisoned baits and ordered to selected institutions and professionals to carry out standardized surveys to assess suspect and/or confirmed reported cases; all the necessary anatomopathological and toxicological investigations to confirm the reported cases were then performed for free by public veterinary health institutes whenever a veterinarian diagnosis or clinical suspicion were provided.

The objective of this study was the estimation of the exposure over time to heavy metals (cadmium, mercury, and lead) due to shellfish consumption in the Veneto Region, Italy. Shellfish consumption was investigated by a food frequency consumption survey. Altogether, 1949 households, stratified into the five most populated areas of the Veneto Region, were involved in the study.
