Abstract

Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii, an intracellular parasite that presents a worldwide risk. Humans can become infected by ingesting meat infected with T. gondii, and the consumption of infected sheep and goat meat is a significant public health issue. Antibodies against T. gondii have been found in sheep in Spain, indicating the presence of the parasite in the country. However, no previous studies have assessed the presence of T. gondii in sheep meat in Spain. In view of the significance of the transmission of T. gondii through meat consumption and given the lack of previous studies in Spain, we carried out an investigation to evaluate the presence of T. gondii in adult sheep meat (mutton). A total of 216 muscle samples were analyzed by digestion, and a real-time PCR assay was used to determine the presence of T. gondii DNA. A total of 24.5% of the samples were found to be parasitized, indicating that the consumption of sheep meat can present an important risk for human health.

西班牙成年绵羊肉中的刚地弓形虫

弓形虫病是由刚地弓形虫引起的人畜共患疾病，弓形虫是一种细胞内寄生虫，在世界范围内具有危险。人类可因食用感染弓形虫的肉类而感染弓形虫，食用受感染的绵羊和山羊肉是一个重大的公共卫生问题。在西班牙的绵羊中发现了针对弓形虫的抗体，表明该国存在这种寄生虫。然而，以前没有研究评估过西班牙羊肉中是否存在弓形虫。鉴于弓形虫通过肉类传播的重要性，以及西班牙以往研究的缺乏，我们开展了一项调查，以评估成年羊(羊肉)中弓形虫的存在。通过消化分析216份肌肉样本，并采用实时PCR检测弓形虫DNA的存在。共有24.5%的样本被寄生，表明食用羊肉可能对人类健康构成重要风险。

期刊介绍： Food and Waterborne Parasitology publishes high quality papers containing original research findings, investigative reports, and scientific proceedings on parasites which are transmitted to humans via the consumption of food or water. The relevant parasites include protozoa, nematodes, cestodes and trematodes which are transmitted by food or water and capable of infecting humans. Pertinent food includes products of animal or plant origin which are domestic or wild, and consumed by humans. Animals and plants from both terrestrial and aquatic sources are included, as well as studies related to potable and other types of water which serve to harbor, perpetuate or disseminate food and waterborne parasites. Studies dealing with prevalence, transmission, epidemiology, risk assessment and mitigation, including control measures and test methodologies for parasites in food and water are of particular interest. Evidence of the emergence of such parasites and interactions among domestic animals, wildlife and humans are of interest. The impact of parasites on the health and welfare of humans is viewed as very important and within scope of the journal. Manuscripts with scientifically generated information on associations between food and waterborne parasitic diseases and lifestyle, culture and economies are also welcome. Studies involving animal experiments must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences.
