Toxoplasma gondii infection can result in toxoplasmosis and potential psychological effects. Research commonly focuses on infection through contact with cat fecal matter or consumption of contaminated meat. However, T. gondii oocysts can persist in the environment for years and may be present in soils and on soil-grown produce. Rates of oocyst DNA recovery from produce were high, with 18% of vegetable samples testing positive for T. gondii via PCR test and melt curve analysis. Radishes had significantly higher oocyst counts than arugula, collard greens, kale, lettuce, and spinach. There were no significant differences in oocyst detection rates between samples taken from organic farmer's markets and conventional grocery stores. This study demonstrates that these oocysts can transfer to produce grown both conventionally and using organic techniques.

弓形虫感染可导致弓形虫病和潜在的心理影响。研究通常侧重于通过接触猫粪便或食用受污染的肉类而引起的感染。然而，弓形虫卵囊可以在环境中存留多年，并且可能存在于土壤和土壤种植的产品中。从农产品中回收卵囊 DNA 的比率很高，18% 的蔬菜样本检测出弓形虫呈阳性通过PCR测试和熔解曲线分析。萝卜的卵囊数量明显高于芝麻菜、羽衣甘蓝、羽衣甘蓝、生菜和菠菜。从有机农贸市场和传统杂货店采集的样本之间的卵囊检出率没有显着差异。这项研究表明，这些卵囊可以转移到常规和有机技术种植的产品中。
