Fishery products infected by parasites as a human health risk
No full textThe Food Safety Law requires food business operators to ensure that the food they place on the market is safe. The absence of visible parasites in fishery products is one of the requirements. After ingestion, parasites present in fishery products can cause infections in humans. The nematode Anisakis spp. is one of the most common parasites associated with the consumption of fish products, and causes anisakiasis, a digestive tract disorder with nonspecific symptoms or an allergic reaction. By visual inspection of the whole fish, Anisakis spp. larvae, cocooned in a spiral shape, 4 to 5 mm in diameter, can be easily observed. The aim of this research is to highlight the significant risks to human health caused by the fishery products infected with parasites. The visual examination of 202 samples of imported fishery products, from January 2023 to March 2025, revealed the presence of visible parasites in 17.83%. Parasites were present in samples of white fish and blue fish, including hake (Merluccius hubbsi and Merluccius productus) (10.89%), Atlantic mackerel (Scomber scombrus) (5.94%), Atlantic chub mackerel (Scomber colias) (0.50%) and herrings (Clupea). Fishery products that are visibly infected with parasites must be frozen or heat-treated to kill live parasites that pose a risk to human health. Since the presence of parasites causes consumer disgust and affects sensory properties, and in addition, allergic reactions may occur due to the ingestion of live or dead parasites, competent authorities and food business operators should conduct continuous risk analysis to reduce risks to consumer health.This study was funded by the Ministry of Science, Technological Development and Innovation of Republic of Serbia (Contract No: 451-03-136/2025-03/20003)

ANT22 - Aqueous Emulsion Control Method: Contribution to Rational Control of Dermanyssus Gallinae in Poultry
No full textRed poultry mite Dermanyssus gallinae (De Geer, 1778) is an ectoparasite that feeds on the blood of birds and
mammals. Invasions of the ectoparasite D. gallinae in intensive poultry farming reach proportions unknown in the
wild nature. They are classified as key health, economic, and ecological problems of the most intensive production of
foodstuffs of animal origin. Annual losses worldwide are estimated at 3.92 billion USD and tend to grow further.
This manifestation of the problem, to a large extent, results from inadequate control of D. gallinae. This study aims
to optimize and rationalize the D. gallinae control by external application of inert oils. The ANT 22 method (working
name) is based on "know-how" formulation and application technology. In this study, a manual application was
carried out in the clinical conditions of 18 small industrial facilities (2,000 - 14,500 animals) of laying hens (cage
system), with a total capacity of 151.300 laying hens, in a time frame of 25 months. The effects of D. gallinae
control (suppression of infestation) in inhabited and empty non-conditional objects with one treatment lasted 4-10
months, and with two treatments lasted 8-10 months. The observed disadvantages of the method are common to inert
oils, which can be minimized with care. The ANT 22 method is safe and does not develop resistance. It is a
conditional method, which requires hygienic preparation and adequate application, and is optimal for empty
buildings with rest. An important technical condition is the correctness of the applicator and a professionally
performed application. Considering the control findings obtained so far, we believe that they justify testing the
application of the ANT 22 method for control purposes in large industrial facilities, but also for the purpose of
eradicating D. gallinae
Essential oils as feed additives: A novel approach to managing poultry red mite infestations and boosting egg production
No full textThis study assessed the efficacy of a plant-based premix of feed additives (PFA) composed
of essential oils and vitamins on a farm with 1560 laying hens (ISA Brown line),
naturally infested with poultry red mite (PRM), Dermanyssus gallinae. The trial lasted
44 days. The AVIVET traps were used to determine PRM mass, number of eggs, larvae,
blood-engorged and unfed nymphs, and adults on day − 12, − 5, and 0 before, and on
days 2, 5, 8, 11, 15, 23, and 30, after, hens started to consume PFA. Friedman’s ANOVA
was utilised to identify differences between means, and the post hoc Wilcoxon matched
Pairs Test was then employed to ascertain the impact of the tested PFA on the D. gallinae
population. From the eighth day until the end of the trial period, a statistically lower mass
of mites (P < 0.05), the number of nymphs (P < 0.05) and the number of blood-engorged
mites (P < 0.05) were observed compared to day 0. In comparison to day 0, a statistically
significantly lower number of eggs (P < 0.01) was observed on day 5 (P < 0.05), day 11
(P < 0.01), larvae on day 23 (P < 0.05) and day 30 (P < 0.01), as well as unfed mites on
days 15, 23, and 30 (P < 0.01, P < 0.01 and P < 0.001, respectively). Egg production (%,
hen-day) in 52–54 weeks of age (control period) was 88.7, while in 55–58 weeks of age
(trial period) was 89.5. The results indicate that the tested PFA can control PRM without
adversely affecting egg production.The research was carried out under contracts 451-03-136/2025-03/200007 (D.T., L.I., and V.P.M.)

Impact of Balkan and Banat Donkey Milk on the Technological Process, Microbiological Quality, Composition, and Consumer Acceptability of Rolled Cheese
No full textDonkey milk is well known for its beneficial properties for human health, making
it a valuable ingredient in the production of value-added cheese. Rolled cheese, a type
of pasta filata cheese, is traditionally produced in the northern part of Serbia. In this
study, we produced rolled cheese by adding a certain amount of donkey’s milk from the
Balkan and Banat breeds to cow’s milk. The rolled cheese samples were analyzed for their
microbiological quality, chemical composition, content of essential and trace elements, as
well as sensory characteristics. Adding 10% and 20% donkey’s milk had no effect on the
microbiological quality or hedonic scale of rolled cheeses compared with rolled cheese
made from raw cow’s milk. However, the addition of donkey’s milk partially affected the
chemical composition and mineral profile of the cheeses. The fat, fat in dry matter, calcium
contents, and the ratio of calcium and phosphorus significantly (p < 0.05) decreased with the
addition of donkey’s milk, while the ash, salt, sodium, and potassium contents significantly
(p < 0.05) increased. The assessors successfully distinguished the rolled cheeses containing
donkey’s milk from those made with cow’s milk, encouraging the future production of
value-added cheese.This research was funded by the Science Fund of the Republic of Serbia (Grant No. 3535),

Advanced Photocatalytic Degradation of Organic Pollutants Using Green Tea-Based ZnO Nanomaterials Under Simulated Solar Irradiation in Agri-Food Wastewater
No full textThe increasing presence of various organics poses significant threats to aquatic
ecosystems and living organisms. Conventional water treatment methods are often insufficient, necessitating the development of powerful and sustainable alternatives. This
study addresses this challenge by exploring the synthesis of ZnO nanoparticles using
green tea leaves extract—an eco-friendly approach—for the sunlight-activated removal
of organics in agri-food wastewater. The research examined different conditions for the
removal of clomazone (CLO), tembotrione (TEM), ciprofloxacin (CIP), and zearalenone
(ZEA). Nitrate-derived ZnO synthesized in a water medium (N-gZnOw) exhibited the
highest photocatalytic activity, removing 98.2, 95.8, 96.2, and 96.6% of CLO, TEM, CIP,
and ZEA. Characterization techniques (XRD, Raman spectroscopy, SEM, zeta potential
measurements, UV–visible spectroscopy) confirmed the synthesis of N-gZnOw, with an
average particle size of 14.9 nm, an isoelectric point of 9.9, and a band gap energy of
2.92 eV. Photocatalytic experiments identified 0.5 mg/cm3 as an optimal catalyst loading,
while a higher initial pollutant concentration reduced degradation efficiency. LC-ESIMS/MS measurements confirmed the efficient pollutant degradation and the formation
of degradation intermediates. Hence, this study demonstrates that green tea extractsynthesized ZnO nanoparticles offer a promising, sustainable solution for removing herbicides, pharmaceuticals, and mycotoxins from wastewater, paving the way for eco-friendly
water purification technologies.This research was funded by the Science Fund of the Republic of Serbia (Grant No. 7747845,
