ABSTRACT Class II genotype IV Newcastle disease virus (NDV), a historically virulent strain responsible for the first Newcastle disease (ND) panzootic from the 1940s to 1960s, was presumed extinct after its last reported isolate in India in 2000. Here, we report the emergence of four virulent genotype IV NDV isolates from 6,731 wild birds and domestic poultry across nine provinces of China between 2021 and 2023, representing the first genetically confirmed isolation of this ancestral genotype in over two decades. These isolates exhibit remarkably high genetic similarity to ancestral strains, showing minimal divergence despite a temporal span of 50–90 years, yet they differ from the most recently reported isolate from India. Infection with the representative isolate, KS02, caused severe lethality and higher transmissibility in specific-pathogen-free chicks than a genotype VII reference virus. Notably, LaSota vaccination provided only limited protection at the conventional hemagglutination inhibition (HI) threshold and achieved complete protection only when HI titers were at least twofold higher, in contrast to the protection observed against genotype VII challenge. This unusual genetic stability raises concerns about the origin and evolutionary history of these viruses as well as highlights the urgent need to update vaccination strategies, including approaches to elicit higher HI titers through intensified immunization schedules. This study underscores the critical importance of sustained global surveillance of genotype IV NDV in domestic poultry and migratory birds to monitor its spread and evolution. IMPORTANCE Virulent Newcastle disease virus (NDV), particularly emerging isolates, poses a major threat to poultry health and production, causing severe morbidity, high mortality, and economic losses. While ancestral class II genotypes II and IX have persisted globally across various bird species, the status of genotype IV NDV—last reported in India in 2000—had been uncertain. This study documents the emergence of genotype IV isolates in wild and domestic birds across China from 2021 to 2023, marking their return after more than two decades of presumed extinction. The representative isolate, KS02, showed severe lethality and high transmissibility in chicks compared to the circulating virus. The LaSota vaccine conferred complete protection against this isolate only when HI titers were at least twofold above the conventional protective threshold. These findings underscore the significant risk posed by reemerging genotype IV NDV, highlighting the urgent need for surveillance and updated vaccination strategies.

THE EFFECT OF LIQUID SMOKE ON FOODBORNE PATHOGENS IN READY-TO-EAT MEAT PRODUCTS

Liquid smoke is increasingly used in ready-to-eat meat products as a natural preservative with antimicrobial and antioxidant properties. This study investigated the efficacy of a commercial liquid smoke preparation (Cloud S9, Kerry, USA) against Listeria monocytogenes ATCC 13932, Escherichia coli ATCC 25922, and Salmonella Enteritidis ATCC 13076 in chicken and beef ham. Meat products were inoculated with each bacterial strain and treated with liquid smoke at concentrations of 1%, 2.5%, and 5%, and untreated samples were used as controls. Bacterial counts were assessed after 2 hours, 7 days, and 14 days of refrigerated storage (4 °C). Liquid smoke significantly inhibited bacterial growth in a concentration-dependent manner. For Listeria monocytogenes, 5% liquid smoke achieved > 2 log cfu/g reductions after 14 days, while lower concentrations suppressed growth without elimination. Escherichia coli and Salmonella Enteritidis exhibited comparatively lower sensitivity, with most treatments producing bacteriostatic rather than bactericidal effects; however, 5% liquid smoke achieved a measurable reduction of Escherichia coli in chicken ham. These findings confirm the antimicrobial potential of liquid smoke as a complementary hurdle to enhance the microbial safety of ready-to-eat meat products, while also underscoring the ongoing necessity for stringent hygiene practices.
