Pattern minas cheese is a product developed with pasteurized milk, fermented with mesophilic cultures, and with the final addition of rennet. This cheese undergoes an artisanal maturation process and possesses a firm shell of yellowish color and striking and acidic flavor. Our study objective was to evaluate the microbiological quality of pattern minas cheese. We collected 40 samples from two micro regions (Uberlândia and Patos de Minas) of the Triângulo Mineiro and Alto Paranaíba mesor regions of the State of Minas Gerais, Brazil. The microbiological test results were recorded as counts of enterobacteria, Escherichia coli, coliforms at 35°C, coagulase-positive Staphylococcus and Salmonella spp. In the Patos de Minas micro region, the results were 45%, 35%, 20%, and 20% higher than 103 CFU/g for the counts of enterobacteria, Escherichia coli, coliforms at 35°C, and Staphylococcus coagulase-positive, respectively. Five percent of the analyzed samples were positive for Salmonella spp. in the Uberlândia micro region. Based on the findings of the microbiota in the cheese analyzed from the micro regions (Uberlândia and Patos de Minas), we concluded that the hygiene conditions in the manufacturing, handling, transport, and storage stages were precarious, requiring the implementation of Good Manufacturing Practices (GMP) systems, including Hazard Analysis and Critical Control Points (HACCP).

Common parasites of the European bison include gastro-intestinal and pulmonary nematodes, liver flukes (Fasciola hepatica), tapeworms, and protozoa of the genus Coccidia. This study compared the extensiveness and intensities of European bison parasitic invasions in three north-eastern Polish forests in different seasons and queried the role of parasitological monitoring in sanitary and hygienic control of feeding places. Faecal samples were collected in the Białowieża, Knyszyńska, and Borecka Forests between 2014 and 2016, as were some from an area neighbouring the Białowieża Forest outside the Natura 2000 protected area. Parasites were detected in individual samples with the flotation, decanting and Baermann methods. The eggs of Trichostrongylidae, Aonchotheca sp., Nematodirus sp., Strongyloides spp., Trichuris sp., Moniezia spp., and Fasciola hepatica; the larvae of Dictyocaulus viviparus; and the oocytes of Eimeria spp. were identified. Significant variation in invasion intensity and diversity was seen by origin and season. The relationships were assessed first by univariable tests and next multivariately, when origin and season emerged as the major risk factors for exposure to most of the parasites. The differences in the level of parasitic infection between the forests did not have implications for its sufficiency to cause clinical symptoms. However, the associations and risk factors found enable the necessary preventive measures to be taken to protect the E. bison from exposure or decrease the risks. Additionally, parasitological monitoring is appropriate as the method of sanitary and hygienic control of European bison winter feeding places. Threats to public health through adventitious invasions by zoonotic factors such as F. hepatica have been identified.

The aim of this paper is to give an overview of the presence of biogenic amines, particularly histamine, in various food products, discuss the most important factors influencing their accumulation, and address potential toxicity and safe limits in food. Biogenic amines are natural components of animal and plant raw materials, where they are present at concentrations appearing non-harmful to human health. Their increased content in foods results from the activity of endogenous enzymes or from the microbial decarboxylation of amino acids during controlled or spontaneous fermentation, processing, storage, and distribution. General knowledge of biogenic amines, factors favouring their formation and their safe limits in food are useful in preventing exposure to their toxic effects on the human body. Based on this information, appropriate prophylaxis can be applied, which will consist primarily of maintenance of good hygiene standards of raw materials and products, employment of appropriate processing procedures and upkeep of sanitary food storage conditions.

Introduction: Studies of anabolic hormone residues in the tissues of slaughter animals have been carried out in Poland for more than 25 years. During the period of 2011 to 2015, a total of 35 387 samples from different animal species were tested in the National Residue Control Programme for the presence of residues of compounds that cause hormonal effects, as listed in Annex 1 of Directive 96/23/EC. Material and Methods: The research was conducted in the National Reference Laboratory and eight regional laboratories in departments of veterinary hygiene located throughout the country. Urine, muscle tissue, serum, kidney fat, and drinking water were the targeted matrices. Test methods based on instrumental techniques such as gas and liquid chromatography coupled with mass spectrometry were applied, as well as enzyme-linked immunosorbent assays (ELISA). Results: The concentration of detected hormones exceeded the decision limits in 30 samples, the consequence of which was 41 non-compliances with current applicable criteria. The hormones found present pseudo-endogenous (nortestosterone and boldenone) only, while synthetic hormones were not identified. Conclusion: The non-compliant findings constitute a small percentage (0.085%) of the five-year analysis compilation. On this basis the related food produced in Poland can be accepted as safe for human consumption with regard to the hormone residues tested.

Introduction: The objective was to evaluate the epizootic and epidemiological situation of Trichinella sp. infection in Poland between 2006 and 2015 against the dynamics of the wild boar population and its primary reservoir host.Material and Methods: Boar and porcine trichinosis epizootic analysis was based on General Veterinary Inspectorate data from RRW-6 bulletins. The epidemiological situation was evaluated on the basis of the data supplied by the Department of Epidemiology of the National Institute of Hygiene - National Institute of Public Health. The wild boar hunting harvest and population dynamics were estimated, as these animals remain the basic infection source for humans. Population size and harvest data were obtained from hunting statistics.Results: The study timeframe showed an almost 2.5-fold increase in Trichinella infection cases in wild boars but a significant decline in human cases. In the domestic pig, the incidence rate did not exceed 0.00037%. The highest infection risk exists in West Pomerania, Greater Poland, and Kuyavian-Pomeranian Provinces. Over the study period, the wild boar population increased more than 1.5-fold, while the hunting harvest more than tripled. During the last two seasons the total hunt surpassed 100% of the spring population.Conclusion: Wild boar management by increasing the hunting take of the annual population growth should limit that growth and decrease the take in the future. Thereby, over some years intra-species trichinosis spread should reduce, for a substantial safety gain for wild boar meat.

This study investigated the eggs of Polish-bred edible snails of the Cornu genus as a food and aimed to determine the presence of microorganisms in them of the Salmonella and Listeria genera and ascertain the number of coagulase-positive staphylococci. Raw material, semi-finished products, and the final product were collected during the production cycle. Testing for the presence of Salmonella spp. and Listeria spp. and measuring of the pathogenic staphylococci contamination level were carried out in accordance with ISO standards. Commercial biochemical tests were used for species identification of bacteria of the Enterobacteriaceae family and Staphylococcus genus. An API kit and a PCR protocol were utilised for species confirmation of the microorganisms of the Listeria genus. Neither Salmonella nor coagulase-positive staphylococci were found in any of the studied material. Bacteria of the Listeria genus were found in samples taken at every stage of production; however L. monocytogenes was confirmed in samples of the final product. The absence of Salmonella spp. and Staphylococcus aureus in samples of the final product indicates that the required hygiene standard was maintained in the production process of edible snail eggs. Nevertheless, the presence of L. monocytogenes in eggs of common garden snails may pose a potential risk to consumer health.

Contamination by Staphylococcus aureus of food produced from animal sources may have diverse and multifactorial causes that depend on geographical distribution. The goal of this study was to isolate and characterise S. aureus strains from contaminated fermented pork sausage, which is a local food of northeastern Thailand. S. aureus strains were isolated from local pork sausage, and the presence of classical enterotoxins was determined by PCR and reversed passive latex agglutination. These results were compared with strains derived from hospitalised patients and healthy carriers. Additionally, production of extracellular enzymes and haemolysin, biofilm formation, and antibiotic susceptibility were assessed. S. aureus was identified in 36 sausage isolates (60%). The strains positive for staphylococcal enterotoxin A were more frequently found in isolates from sausage and healthy carriers than in those from patients. All tested S. aureus strains were positive for DNase, lipase, proteinase, haemolysin, and biofilm formation; notably, strains isolated from food and healthy carriers displayed similar values. Most isolates were resistant to penicillin and ampicillin, while none were to methicillin. Thai fermented pork sausages are associated with a high risk of staphylococcal food poisoning, which may be linked to contamination caused by carriers. Dissemination of knowledge regarding best practices in sanitation and hygiene is important in local communities.

A total of 103 blood samples from pet dogs around Ipoh were screenedfor common blood protozoa. A total of 14 samples were found positive for Erhlichia canis and one sample was found positive for microfilaria of Dirofilaria immitis. Both these diseases are transmitted by vectors; ticks (Rhipicephalus sangiuneus) and mosquitoes respectively. In the hot and wet tropical environment where vectors are abundant, pet care, hygiene and regular screening will help veterinarians detect these infections early to facilitatetreatment.

A rare case is presented of a 58-year-old woman who developed ahepatic-bronchopleural fistula following a hydatid hepatic cyst complication. The hepatic-bronchopleural fistula was diagnosed when patient complained of severe repetitive attacks of productive cough of brown yellow to dark colour sputum biliptysis (bile in cough) with vomiting associated with night sweating and fever, for the past one month. She also complained of right side chest and abdominal pain for the past 3 years. This paper describes a unique case of hepatic-bronchopleural fistula caused by hydatid disease, emphasising the clinical feature and its surgical management. Hydatid disease is a zoonotic infection dueto the damage caused by Echinococcus granulosus. E. granulosus, also called the hydatid worm, hyper tape-worm or dog tapeworm, is a cyclophyllid cestode that parasitises the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease. It is hoped thatthis case report will add to the meagre case management reports of hepaticbronchopleural fistula in literature.

In most countries, poultry are reared by traditional farmers d ue tothe relative minimum capital needed to start off, availability of feed and the fast period of the birds to grow. This research was conducted on turkeys which aims to study the abundance and prevalence of ectoparasites from three localities around Kedah, Malaysia. Atotal of 20 turkeys (eight males and twelve females) were examined for ectoparasites infestation and endoparasites infection.Six species of ectoparasites: five lice and a mite have been discovered. The most prevalent ectoparasite was Menopon gallinae with occurrence of 45%. Other external parasites recorded includeLipeurus caponis and Megninia cubitalis with occurrence of 40%, Menacanthus pallidulus (35%), Goniocotes gallinae (30%) and Chelopistes meleagridis (20%). There was a significant difference between the ectoparasite abundance in Jabatan Perkhidmatan Veterinar and Alor Belat Barat [ANOVA, F(2,17)=6.33, p=0.009]. These lice commonly found in the fluff of the feathers, especially at the neck,abdomen, and wings. Lipeurus caponis was found to have the highest infestation in all male and female turkeys and Menacanthus pallidulus was noted as the less common ectoparasite infesting both the male andfemale turkeys. Endoparasite infection was recorded in two species of parasite eggs of nematodes and protozoa. Oocyst of Eimeria spp. recorded the highest faecal egg count with 7300 epg compared to Capillaria spp. with only 1200 epg. Scavenging and pecking behaviour of turkeys in barn area with unsuitable farm housing environmentwere the major contributing factors to the infestation of ectoparasites as well as endoparasites infection.
