Staphylococcus aureus in rabbit meat is a consequence of insufficient hygienic handling and improper processing posing a major health hazard. This study was conducted to assess rabbit meat as a potential source of Staphylococcus species, particularly Staphylococcus aureus (S. aureus). Furthermore, the identified S. aureus isolates were tested for the detection of the mecA virulence gene of methicillin-resistant Staphylococcus aureus (MRSA) and enterotoxin encoding genes (Sea, Seb, Sec, and Sed). A total of 80 samples of different rabbit meat cuts represented by shoulder, ribs, loin, and thigh (20 of each) were collected from various markets of different sanitation levels. The results obtained revealed that the mean counts of Staphylococcus species were 7.40× 105, 7.58× 105, 7.60× 105 and 8.29× 105 CFU/g in the examined shoulder, ribs, loin and thigh samples, respectively. Out of 17 identified S. aureus isolates, 5 (29.4%) strains were characterized by the presence of the mecA gene. A large proportion of the isolates obtained were resistant to at least three antibiotics. Enterotoxins were evaluated by ELISA. The results showed that three strains isolated from shoulder produced Sea, Seb, and Sec enterotoxins, the strains isolated from ribs failed to produce enterotoxins, while two strains isolated from loin and thigh produced Sea enterotoxin. The presence of S. aureus, especially MRSA strains, in the examined rabbit meat indicates the necessity of enforced application of strict hygienic measurements.

Concerns about potential health risks have made heavy metal contamination in food a prominent issue. The primary route of human exposure to metals is through food consumption. Hence, the objective of this study was to assess metal concentrations in game bird meat and calculate daily intake and associated health risks. An ICP-OES was employed to measure the levels of mercury (Hg), lead (Pb), arsenic (As), cadmium (Cd), chromium (Cr), magnesium (Mn), zinc (Zn), copper (Cu), cobalt (Co), and iron (Fe). The study's results indicated that As, Zn, and Fe were present at relatively high levels in the studied groups, while Co, Hg, Cr, and Cd had comparatively lower mean concentrations. Among the detected heavy metals, there were no statistically significant differences between the three studied groups, except for Cr, Co, and Zn, which exhibited statistically significant variations. Most quails and pigeons stayed within the designated permissible limits (PL) for Hg, while sparrows exceeded these limits. Both quails and sparrows also exceeded the PL for Pb, whereas pigeons remained within it. In the case of Zn, Cu, and Co, the majority of the three species adhered to the PL, while they exceeded the PL for As. However, all three species remained within the PL for Cd and Cr. Despite the Hazard Quotients (HQs) for the tested heavy metals, with the exception of As, Fe, and Zn, not exceeding 1, this suggests that consuming game bird meat is unlikely to significantly elevate the risk of human exposure to these specific metals, indicating a lower potential health hazard.

Chicken meat products contribute significantly as a fairly priced substitute for red meat, which is critically undersupplied in Egypt. This type of meat is high in animal protein, vital amino acids, and trace elements. Furthermore, as a result of rapid improvements in food processing and technology, a variety of chicken meat products, including as chicken burgers, chicken fillets, chicken sandwiches, chicken nuggets, and chicken panne, were manufactured and released into the chicken meat markets. Such key products are defined by their distinct flavor and aroma, which captivates buyers, particularly children. Microorganisms can contaminate chicken meat products at any stage of production, including raw material preparation, manufacture, distribution, and storage. As a result, chicken products are regarded to be a possible source of bacteria that cause food poisoning, such as Staphylococcus aureus (S. aureus) and Salmonella spp. Essential oils derived from the coriander plant (Coriandrum sativum L.), either from the seeds or the leaves, are among the most extensively utilized. Coriander and coriander essential oils are antibacterial, anti-oxidant, anti-diabetic, anxiolytic, anti-epileptic, depressive, anti-mutagenic, anti-inflammatory, antidyslipidemic, antihypertensive, neuroprotective, and diuretic. In this review, we threw the light on the microbial contamination of chicken meat and meat products in Egypt and worldwide. Besides, the antibacterial activities of coriander will be reviewed.

Rabbit meat is one of the most consumed meats throughout the world and is extremely susceptible to spoilage due to its high protein and moisture content. Natural preservatives with antioxidant and antibacterial properties are needed to maintain meat quality and increase its shelf life. This study examined the effect of 1% chitosan (CH), 0.2% rosemary (Salvia rosmarinus) essential oil (REO), and their combination on pH, total volatile basic nitrogen (TVB-N) and thiobarbituric acid (TBA) levels, and the microbial profile of rabbit meat stored over 12 days at 4 °C. During this time, changes in appearance, odor, and texture were also noted. The shelf lives of samples treated with only 1% CH coating, or in combination with 0.2% REO, were longer than those of untreated samples. These results showed that samples treated with both CH and REO were still acceptable until the 12th day and resulted in significantly lower …

Chicken meat products represent an important source of animal derived proteins, vitamins, and minerals. However, chicken meat products might act as potential sources of human exposure to foodborne pathogens such as Staphylococcus aureus (S. aureus) and Salmonella species. The objectives of the present study were first to investigate the prevalence rates of S. aureus and Salmonella species in the retailed chicken meat products at Zagazig city, Egypt. Second, serological identification of the isolated bacteria was followed. Third, screening of S. aureus enterotoxin coding genes (sea seb, and sed) as well as Salmonella virulence associated genes including invA, Salmonella hyper-invasive locus (hilA), and Salmonella enterotoxin (stn) was done using PCR. The obtained results revealed isolation of S. aureus from the examined chicken meat products at 22%, and Salmonella spp., at 6.66%. Where S. aureus was isolated at 33.33%, 36.66%, 13.33%, 6.66%, and 20% from the examined chicken burger, fillet, luncheon, nuggets, and panne, respectively. Salmonella spp. could be isolated only from chicken burger and fillet at 10%, and 23.33%, respectively. The recovered S. aureus isolates harbored enterotoxin coding genes (sea, and seb). Likely the recovered Salmonella spp. isolates harbored virulence associated genes such as invA, hilA, and stn. Moreover, antimicrobial sensitivity testing of the recovered isolates showed multidrug resistance profiling. In conclusion, chicken meat products retailed in Egypt might be potential sources for the spread of multidrug resistant S. aureus and Salmonella spp. Therefore, strict hygienic measures should …

Due to their great nutritional value, distinct scent and taste, and lower price in contrast to other usual sources of protein, game birds' meat products are in higher demand. Toxic metals including lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As) are still present in these items, but there is a glaring lack of information on their presence. Therefore, this analysis was done to determine the residual level of lead, mercury, cadmium and arsenic were still present in three different types of game bird’ s meat, including pigeons, quails and sparrows. According to the study’ s findings, Pb, Cd, Hg, and As were detected at variable concentrations in the tested samples. Residual concentrations of the tested metals in several samples are over the suggested maximum permissible limits (MPL). However, Cd was low in all samples and did not exceed MPL. Furthermore, the HQ ranged from 0.04 to 0.22 for cadmium, 1.16 to 1.34 for arsenic, 0.06 to 0.07 for lead and 0.05 to 0.35 for mercury. Although HQs of studied heavy metals except for arsenic did not exceed 1, it supposedly demonstrates that eating the meat of game birds does not pose a significant health risk to people for ingesting the particular metals.

Fish is an excellent source of protein and other essential minerals and vitamins; nevertheless, several food-borne disease outbreaks have been linked to the consumption of different types of fish. Therefore, we aimed to overcome these health threats by evaluating gamma radiation as a good fish preservation method. The aerobic plate count (APC), identification of most common pathogenic bacteria, organoleptic properties, proximate composition, and other chemical evaluations were detected in both untreated and gamma-treated fish. The overall grades of organoleptic evaluations ranged from good to very good. Fortunately, the overall chemical analysis of all examined fish samples was accepted. For the untreated fish samples, the APC was within and above the permissible limit (5 × 107 CFU/g). Pathogenic bacteria were detected with a high prevalence rate, especially S. aureus, which was found in high percentages among examined untreated fish samples. Regarding the treated fish samples, APC and pathogenic bacterial counts were reduced in a dose-dependent manner, and the irradiation at dose 5 KGy resulted in complete eradication of the aerobic plate count (not detectable) with a mean reduction percentage equal to 100%. However, gamma irradiation has no significant effect on proximate composition; particularly, carbohydrates, proteins, and lipids were not significantly affected by low and medium doses of radiation. Therefore, gamma irradiation is a highly effective fish preservation method without any effect on fish quality. Additionally, gamma irradiation as a cold process is an attractive technology for solving the problem arising …

Simple Summary Staphylococcus aureus is a prevalent foodborne bacterium causing significant morbidity, mortality, and economic loss, due especially to pathogenic and multidrug-resistant (MDR) strains. This study focused on determining the prevalence of S. aureus in chicken meat in Egyptian markets and assessing the effectiveness of natural phenolic compounds as novel antibacterial agents against MDR S. aureus. The study found that 91.3% of chicken meat parts were contaminated with S. aureus, with 81.8% of the isolates being MDR. Twenty-two antibiotic resistance patterns were identified, and six strains showed the highest combination of virulence and resistance genes. The phenolic compound hydroquinone exhibited the most potent antibacterial activity compared to other compounds, making it a potential alternative to conventional antibiotics against the pathogenic MDR S. aureus found in raw chicken meat. This study highlights the need for urgent interventions to improve hygiene for safer meat in Egyptian markets and suggests hydroquinone as an effective natural compound for inhibiting foodborne pathogens. Abstract Staphylococcus aureus is one of the most widespread foodborne bacteria that cause high morbidity, mortality, and economic loss, primarily if foodborne diseases are caused by pathogenic and multidrug-resistant (MDR) strains. This study aimed to determine the prevalence of S. aureus in chicken meat in Egyptian markets. Thus, this study might be the first to assess the efficiency of different natural phenolic compounds as novel antibacterial agents against MDR S. aureus pathogens …

Chicken meat and meat products are considered as significant sources of high quality animal derived protein, essential amino acids, minerals, and vitamins. Besides, chicken meat is regarded as alternative cheap source of protein compared with the red meat. However, chicken meat can be contaminated with a vast array of microorganisms, and subsequently it can be implicated in many biological hazards such as bacterial food poisoning. The latter can be divided into bacterial foodborne infections including E. coli, Salmonella spp., Campylobacter spp., Listeria monocytogenes, Shiegella spp., and Yersinia spp. Bacterial foodborne intoxication including Staphylococcus aureus, and Clostridium botulinum. The third class of the bacterial food poisoning is foodborne toxicoinfection which involves Clostridium perfringens, and Bacillus cereus. This review threw the light on the current scenario of the contamination of the poultry meat with some bacterial hazards in Egypt and worldwide. Besides, the public health significance of such hazards was also discussed.

An abattoir survey was conducted from October 2020 to September 2021 to identify the primary reasons for offal and carcass condemnation of slaughtered animals in Dakahlia province, Egypt, as well as to estimate their economic loss. During the survey, 643 animals (441 cattle, 178 buffalos, 19 camels, 4 sheep, and one goat) were submitted for antemortem and postmortem inspection. The results of both inspections were collected, analyzed, and the total economic loss was estimated by adding the condemnation of offal and carcasses over a twelve-month period. Retail prices for offal (liver, lung, heart, and tongue) and carcass prices per kg were obtained from local markets. Out of 643 animals slaughtered, 2 (0.31%) were totally condemned. In addition, postmortem inspection revealed that 217 (33.74%) livers, 158 (24.57%) lungs, 5 (0.78%) hearts, 14 (2.18%) heads, and 11 (1.71%) tongues were condemned. Offal were condemned mainly due to pneumonia, fascioliasis, telangiectiasis, necrosis, and hydatidosis, whereas carcasses were rejected due to generalized tuberculosis. According to this study, the financial loss at the abattoir owing to carcass and organ condemnations was 244066 Egyptian Pounds over a twelve-month period (15746 USD). The incidence of meat rejection and subsequent financial loss was high compared to the amount of local revenue. The current study concluded that bacterial and parasitic diseases are still prevalent and cause significant economic damage in Dakahlia province, Egypt. This abattoir survey offered regional information on the principal reasons for carcass and organ condemnation in slaughtered …

As poultry organ meat is widely consumed, especially in low- and middle-income countries, there is reason to investigate it as a source of Salmonella infections in humans. Consequently, the aim of this study was to determine the prevalence, serotypes, virulence factors and antimicrobial resistance of Salmonella isolated from chicken offal from retail outlets in KwaZulu-Natal, South Africa. Samples (n = 446) were cultured for the detection of Salmonella using ISO 6579-1:2017. Presumptive Salmonella were confirmed using matrix-assisted laser desorption ionisation time-of-flight mass spectrometry. Salmonella isolates were serotyped using the Kauffmann–White–Le Minor scheme and antimicrobial susceptibility was determined by the Kirby–Bauer disk diffusion technique. A conventional PCR was used for the detection of Salmonella invA, agfA, lpfA and sivH virulence genes. Of the 446 offal samples, 13 tested positive for Salmonella (2.91%; CI = 1.6–5). The serovars included S. Enteritidis (n = 3/13), S. Mbandaka (n = 1/13), S. Infantis (n = 3/13), S. Heidelberg (n = 5/13) and S. Typhimurium (n = 1/13). Antimicrobial resistance against amoxicillin, kanamycin, chloramphenicol and oxytetracycline was found only in S. Typhimurium and S. Mbandaka. All 13 Salmonella isolates harboured invA, agfA, lpfA and sivH virulence genes. The results show low Salmonella prevalence from chicken offal. However, most serovars are known zoonotic pathogens, and multi-drug resistance was observed in some isolates. Consequently, chicken offal products need to be treated with caution to avoid zoonotic Salmonella infections.

Anisakid nematodes have been found in a variety of marine fishes worldwide and they are known to cause anisakiasis and allergic symptoms in human. One-hundred and five fish specimens of different sizes of red porgy (Pagrus pagrus) were collected randomly from Sharkia fish markets originating from the Gulf of Suez, Red Sea, Egypt and examined for the presence of ascaridoid nematodes. The overall prevalence of ascaridoids was 36.19%(38/105). Four morphotypes belonging to two genera of anisakid nematodes (Anisakis type I and Terranova type II larvae) as well as one genus of raphidascarid; Hysterothylacium (larvae and adult) were reported during this study. Hysterothylacium larvae were the most predominant species (23.81%) and abundance value= 1.68. Interestingly, Pagrus pagrus was found as new host and locality records for larvae of Terranova type II. The results revealed a significant statistical correlation between fish length and number of the recovered ascaridoid nematodes (r s= 0.244, P< 0.05). There was a positive correlation between the host length and presence of Anisakis type IL 3 (r s= 0.276, P< 0.001). Significant differences were observed between the occurrence of Terranova type II L 3 and Hysterothylacium L 3 occurrence (r s= 0.388, P< 0.001) and adult (r s= 0.442, P< 0.001). In addition, a highly significant relationship was observed between the presence of Hysterothylacium L 3 and adult (r s= 0.428, P< 0.001). Furthermore, the obtained results were lower than the recommended Egyptian standards (Ë ‚100 parasites/fish), demonstrating that human health risk through consumption of fish flesh is not possible.

Chicken meat products have a high biological value; they are good sources of amino acids, vitamins, and minerals. Despite this high biological value, these products act as a good substrate for different types of bacteria and have been implicated in many foodborne disease outbreaks. Therefore, a total of 60 random samples of chicken meat products (nuggets, luncheon and pane, 20 of each) were collected from Zagazig City, Sharkia Governorate, Egypt for bacteriological examination (Aerobic Plate Count, Staphylococci count, Pseudomonas count, determination of most probable number of Coliform and E. coli.). The obtained results revealed that the mean aerobic plate counts were 5.18 ±0.19, 4.88 ±0.20 and 4.73 ±0.29 log 10 CFU/g; Staphylococci counts were 2.96 ±0.20, 3.14 ±0.21 and 3.32 ±0.16 log 10 CFU/g; Pseudomonas counts were 2.17 ±0.30, 2±0.28 and 2.34 ±0.21 log 10 CFU/g; most probable numbers of Coliforms were 3.37 ±0.11, 3.83 ±0.27 and 3.64 ±0.30 log 10 CFU/g; and most probable numbers of E. coli were 2.14 ±0.17, 2.56 ±0.30 and 2.64 ±0.25 log 10 CFU/g in the examined nuggets, luncheon and pane, respectively. According to the Egyptian Organization for Standardization and Quality (EOS), the examined chicken product samples were 10 (21.67%), 9 (15%), 28 (46.67%), 49 (81.67%), 31 (51.67%) and 30 (50%) accepted for aerobic plate count, Staphylococci count, S. aureus, Pseudomonas count, Coliform and E. coli, respectively.

Egypt has several beaches, as well as the Nile River and a few lakes; therefore, it could compensate for the lack of protein in red meat with fish. Fish, however, may become a source of heavy metal exposure in humans. The current study was to assess the level of five toxic metals, lead (Pb), cadmium (Cd), mercury (Hg), arsenic (As), and aluminum (Al), in six species, namely, Oreochromis niloticus (O. niloticus), Mugil cephalus (M. cephalus), Lates niloticus (L. niloticus), Plectropomus leopardus (P. leopardus), Epinephelus tauvina (E. tauvina), and Lethrinus nebulosus (L. nebulosus), collected from the El-Obour fish market in Egypt. The residual concentrations of the tested toxic metals in the examined O. niloticus, M. cephalus, L. niloticus, E. tauvina, P. leopardus, and L. nebulosus species were found to be higher than the European Commission's maximum permissible limits (MPL) for Pb and Cd by 10 and 20%, 15 …

In the aquatic environment, pollution with heavy metals is a major issue. Some of them are essential heavy metals because they play biological roles for aquatic organisms. Other heavy metals, however, are regarded as dangerous even at low concentrations. Heavy metal levels that are harmful may be caused by industrial, mining, and agricultural operations. Water contamination and changes to the physicochemical properties of the aquatic environment will result from this. The harmful toxic consequences of this pollution on fish raise questions about its possible impacts on human health. The most prevalent heavy metals are arsenic, cadmium, lead, and mercury, which are systemic toxicants and have an impact on human health. These metals are classified as carcinogens by the United States Environmental Protection Agency and the international agency for research on cancer because they cause organ damage even at low exposure levels. This review was created to contribute to the understanding of the environmental impact, toxicology, and consequences of heavy metals on fish.

With increased consumer knowledge about the relationship between diet and a healthy lifestyle in recent decades, there has been an increase in awareness and demand for efficient protein sources. Rabbit meat is rich in easily digestible protein, polyunsaturated fatty acids (PUFAs), vitamins, and minerals (such as calcium, magnesium, and zinc), as well as being low in fat, sodium, and cholesterol, which makes it of good edible and nutritional value, so it needs to be handled properly. Rabbit meat, on the other hand, has been associated with the spread of microbial contamination (such as Staphylococcus aureus, E. coli and Salmonella species) that may originate from the animal itself, equipment, workers, or the surrounding environment. Each effort must be made to keep rabbit meat free of contaminants that could be harmful to humans. Few studies had been conducted, either internationally or in Egypt, to examine the physicochemical and microbiological characteristics of rabbit meat. We shall compile existing data on the quality of rabbit meat in this review. Furthermore, the potential hazards that influence the physicochemical and microbiological qualities and shelf life, as well as the proposals for decontamination trials to enhance the sensory attributes and shelf life of rabbit meat, will be presented.

Ensuring food safety and strict hygienic practices adopted across the meat industry's whole supply chain is a primary responsibility of the food safety sector. Monitoring the sanitary status of the retailed meat products is necessary to complete this task. Meat products including luncheon, sausage, burger, and minced meat retailed in Sharkia governorate, Egypt, were evaluated for hygiene indicators such as total bacterial counts (TBC), total coliforms counts (TCC), total Staphylococcus aureus (TSC), and total mold counts (TMC). Furthermore, isolation of some pathogenic microorganisms such as Salmonella spp., and Listeria spp., was done. The results showed varying rates of microbial contamination in the examined meat products. Minced meat was generally the most contaminated with microorganisms. Salmonella spp., and Listeria spp., were isolated from the examined samples at varying rates. In conclusion, to produce meat products of excellent keeping quality, it is strongly advised to follow stringent hygiene procedures when handling meat from the time of slaughter and though out all manufacture process

Meat products are regarded as major sources of essential amino acids, minerals, and vitamins. However, during all stages of the processing of meat products, including the slaughter of the animal, dressing, evisceration, and subsequent transportation and distribution, may expose the product to a wide range of bacteria. The microbial community of the finished goods may be influenced by handling and raw materials used in the production of the meat products. The microbiological condition of meat products may be affected by a number of factors, including worker hands, clothing, knives, cutting boards, slaughterhouse and meat processing plant environments, including walls, floors, washing water, etc. Listeria monocytogenes (L. monocytogenes) is considered as one important foodborne pathogen that is responsible for many cases of food poisoning among consumers worldwide. This study aimed at investigating the current scenario of the prevalence of L. monocytogenes in retailed meat products in Egypt and worldwide. The cited literatures in the current review demonstrated that effective sanitary practices should be used throughout all phases of handling meat to produce meat products with a high level of storage quality and free from L. monocytogenes.
