The high quality of food depends on a number of conditions, including the technology of their processing, as well as on the sanitary condition at the enterprise. The purpose of this work is the selection of disinfectants of a certain composition, assessment of toxicity and their danger during the processing of various objects at food processing enterprises. Materials and methods. Disinfectants based on hydrogen peroxide (PV), peracetic acid (NAC), quaternary ammonium compounds (CH), triamines, chlorine dioxide intended for processing technological equipment, food (egg shells, fruits, vegetables, greens), indoor surfaces and air were studied. The safety assessment of residual amounts of disinfectants on technological equipment and food was carried out by the in vitro method on a suspension culture of mobile mammalian cells (bull spermatozoa) on an automatic device "Image Analyzer AT-05". Results and discussion. The concentration of a working solution of a disinfectant based on PV and NUC (0.02 % by NUC) was determined, after processing of which washing of technological equipment made of metals is not required, with the exception of equipment for the manufacture of baby food. The minimum washing time is set (1 min) eggshells and vegetables after treatment with products based on PV and NUC. After treatment with agents containing an HOUR and triamines, the washing time is at least 2–5 minutes, depending on the concentration of working solutions. Products containing only triamines as an active substance cause the destruction of the structure of greenery. The assessment of the real danger of a disinfectant based on chlorine dioxide at a concentration of 12 % in the form of aerosol particles with a size of 10–20 microns (wet mist) during air treatment was carried out. The consumption rate of the product is 50 ml/m3. High concentrations of chlorine dioxide remain during exposure (30 min) and are removed after fog subsidence and intensive ventilation for 120 min. The concentration of chlorine dioxide in the air of the treated room immediately after treatment exceeded the maximum permissible concentration in the air of the working area by 600 times. Conclusions. Disinfection of SIP systems by means based on PV and NUC is possible without additional washing after treatment. For disinfection of eggshells, greens, it is advisable to use products based on PV and NUC. Air treatment with chlorine dioxide, in view of its high danger, should be carried out remotely.
Keywords: disinfectants, hydrogen peroxide, peracetic acid, chlorine dioxide, quaternary ammonium compounds, food and processing industry, food industry, in vitro.

In the context of the coronavirus pandemic, one of the priority tasks is the disinfection of environmental objects in order to comply with the anti-epidemic regime. In this regard, questions arise regarding the laboratory control of the effectiveness of disinfection measures. The use of virological approaches is hardly acceptable for solving this problem, and the use of fast and affordable methods of molecular genetic analysis comes to the fore, which are certainly of signal value, but sufficient to evaluate the effectiveness of these measures. In this work, studies were carried out on the detection of SARS-CoV-2 coronavirus RNA by several test systems using the real-time polymerase chain reaction method in swabs from various surfaces after they were treated with a disinfectant. The study showed that to control the decontamination of environmental objects potentially infected with the SARS-CoV-2 coronavirus, test systems can be used to detect the RNA of the SARS-CoV-2 virus in clinical samples. The greatest sensitivity is shown for PCR kits in which multichannel detection of individual RNA sites is carried out.
Keywords: disinfectants, decontamination control, novel coronavirus infection COVID-19

This review describes nanosized particles of metals, oxides and organic substances that can act as effective disinfectants when irradiated with ultraviolet and visible light. Such an effect is due to photocatalytic action, namely the release of reactive oxygen species, leading to oxidative stress in pathogenic microflora. The review gives a description of the physical and chemical principles of such particles, the variety of their types, methods of their synthesis, and examples of their application. The data from the articles of the last few years from the leading international scientific journals are cited and promising directions for further work are outlined.
Keywords: titanium dioxide, zinc oxide, copper oxide, nanopowders, nanoparticles, photocatalysts, reactive oxygen species (ROS), antimicrobial properties, resistance, oxidative stres.

New strategies for control of insecticide-resistant german cockroaches
O.Yu. Eremina, V.V. Olifer
Institute of Disinfectology of the Federal Scientific Center of Hygiene named after F.F. Erisman: 18 Nauchny proezd, Moscow, 117246, Russian Federation.
In a review of foreign literature, the issues of biological methods for controlling synanthropic cockroaches, including the use of entomopathogenic fungi such as Metarhizium and Beauveria, are considered, due to high biodegradability and species-specificity, is a potential alternative to the chemical method. It has been shown that the combination of chemical and biological agents in cockroach control can slow down the emergence of insect resistance and enhance the insecticidal effect. The densonucleosis viruses BgDNV and PfDNV may be required for the biological control of cockroaches due to such features as rapid replication, high specificity, and pathogenicity for the host. In view of the close relationship between symbiotic microorganisms and host physiology, insect control strategies using transgenic symbionts have become the subject of research. Significant differences in the composition of the intestinal microbiota between the pyrethroid-resistant and insecticide-susceptible strains of the German cockroach were found. A new potential direction for insect resistance management has been identified.
Keywords: entomopathogenic fungi, German cockroach, microbiota, symbiotic microorganisms.

The morbidity of human lice in the Russian Federation in 2016–2021 was analyzed. High intensive infection rates were registered in the Central, Northwestern and Far Eastern Federal Districts. The maximum level of pediculosis infestation of the population was noted in Moscow (88.7–96.1 % of all cases of this disease in the Central Federal District). The resistance of lice to permethrin led to a decrease in the pediculicidal activity of pediculicides based on it. The range of modern drugs effective against permethrin-resistant head and body lice and the dynamics of the ratio of pediculicides based on substances from different groups of insecticides during 1991–2021 were analyzed.
Keywords: pediculosis, Pediculus humanus, resistance, pyrethroids, pediculicides.

Annual submissions regarding ixodic ticks suction are registered in Khabarovsk. The research presents data of entomological observations of ixodic ticks population as well as their infection rate with tick-borne infections in the Khabarovsk city and its rural zone. Circulation of six epidemiologically significant species of Ixodidae family ticks that belong to three genus were detected in natural and anthropogenically transformed biocenoses of the Khabarovsk city and its rural area: Ixodes (I. persulcatus, I. pavlovskyi), Haemaphysalis (H. japonica, H. concinna) and Dermacentor (D. silvarum, D. reticulatus). Study revealed that I. persulcatus ticks were infected as well as greater number of tick-borne infections pathogens were isolated in this tick species, which specifies their high epidemiological significance. The fact of discovery of new types of carriers necessitates studies for evaluation of their infection rate and clarification of their role as tick-borne infection vectors.
Keywords: ixodic ticks, infection rate, tick-borne infections, rural zone, urban environment.

In order to detect antibodies to hantaviruses – pathogens of hemorrhagic fever with renal syndrome selectively over 2 periods: (80-90s of the 20th century and 2006-2016), the population of 21 districts of the region and the city of Ulyanovsk was examined. Sera were examined by indirect immunofluorescence (RNIF). The obtained results indicate changes in the loymopotential of natural foci of hemorrhagic fever with renal syndrome, which is confirmed by the indicators of the immune layer and the incidence of the population in the studied territories. It has been shown that the epidemic potential of natural foci of hemorrhagic fever with renal syndrome in the Ulyanovsk region is determined by the nature of the landscape. The risk of infection of the population is maximum in the zone of broad-leaved forests, minimal in the agricultural (steppe) landscape.
Keywords: hemorrhagic fever with renal syndrome, immune layer, landscape.
