The Porcine Reproductive and Respiratory Syndrome (PRRS) eradication program in Hungary, implemented between 2014 and 2022, utilized complete herd replacement and the introduction of high-performance breeds to enhance production efficiency and environmental sustainability in the swine sector. As a result, the sow population was reduced by 26.2% while maintaining nearly the same number of slaughter pigs. This led to significant reductions in ammonia emissions (−145,857 kg), slurry production (−153,879 m³), nitrogen emissions (−1,409,951 kg), and overall greenhouse gas emissions (91,768,362 kg CO2eq). Additionally, the feed and water consumption were substantially decreased by 53,237,805 kg and 292,978,094 L, respectively, further lowering the sector’s environmental footprint. The study demonstrates the effectiveness of customized eradication strategies and advanced breeding practices in reducing the environmental impact of animal husbandry. These findings underscore the necessity for ongoing collaboration among scientists, policymakers, and industry stakeholders to develop and implement sustainable livestock production methods. The Hungarian experience provides valuable insights into how targeted interventions can simultaneously improve production outcomes and reduce the environmental burden in the swine industry.

The emergence and spread of vector-borne diseases necessitate the increased use of insecticides, such as carbamates, raising concerns about their potential toxicological risks to non-target organisms, including humans. Bendiocarb, frequently applied in indoor spraying operations and detected in maternal and fetal circulation, warrants particular attention for its developmental toxicity. This study aimed to assess transcriptional and phenotypic effects of sublethal bendiocarb exposure at concentrations of 0.035, 0.2, 0.4, 0.75, and 1.5 mg/L, using zebrafish embryos, a vertebrate model for developmental toxicity testing. Our analyses revealed acetylcholinesterase inhibition-associated morphological and behavioral abnormalities, including reduced locomotor activity in response to both visual and tactile stimuli, as well as impaired non-associative learning. Transcriptomic analysis indicated activation of muscle, immune, and metabolic pathways, while neurodevelopmental, phototransduction, and cell proliferation processes were suppressed. Consistent with these molecular findings, structural damage was observed in the retina, skeletal muscle, and notochord. Furthermore, bendiocarb exposure disrupted neutrophil granulocyte distribution and impaired inflammatory responses. Altogether, our results provide new insights into the embryotoxic effects of bendiocarb, highlighting its potential to disrupt early vertebrate development. These findings provide mechanistic insight that may support more informed evaluations of potential public health risks associated with developmental exposure to carbamates.
