Risk Assessment for Giardia in Environmental Samples

Abstract: Giardia is a gastrointestinal parasite that causes infections in humans worldwide. In developing countries, giardiasis is an emerging infection because it plays an important role in diarrhea outbreaks linked to water and food consumption affecting the population in general. Giardiasis is referred to as zoonosis because its biological etiological agent is transmitted to humans through animal reservoirs by oral-fecal route. Detection and occurrences of Giardia cysts have been documented in water, food, soil, and… Show more

“…If we take into account the high frequency that we observed in this study with respect to G. intestinalis cysts in stray dogs, as well as the low dose required to infect another canine and cause the disease [6], this may suggest a high risk to public health due to environmental contamination, due to the cysts capacity to remain viable in water, food, and open grass-filled areas [5]. For this reason, parks are perfect sources of infection for domestic dogs and humans, as they are important recreational spots.…”

“…It belongs to the class Zoomastigophorea, order Diplimonadida, and is of worldwide distribution [1,2,3]. The parasite forms cysts, which are then excreted in the stool; cysts are capable of surviving in the environment, and fecal–oral transmission begins with the ingestion of the cysts, and at least 10 cysts need to be ingested to cause disease [4,5,6]. This parasitosis, as is the case with other gastrointestinal diseases, is generally the result of poor hygiene in the food-preparation process [7].…”

“…Despite having been discovered 400 years ago, the disease is considered a re-emerging disease [ 4 ]. Worldwide, about 200 million people are reported to be infected with the parasite, mainly in Asia, Africa, and Latin America, and approximately 500,000 new cases are reported annually [ 5 ].…”

“…Los alimentos pueden contaminarse por la inadecuada manipulación durante su preparación (Balderrama-Carmona et al, 2017), verduras y frutas pueden ser contaminadas con quistes de Giardia spp durante el riego y/o la fertilización con abono orgánico animal (Escobedo et al, 2012;Phuc Pham et al, 2011). Así también el lavado con agua contaminada con quistes del parásito y/o durante los empaques, conservación y transporte pueden ser un punto crítico para contaminar frutas y verduras (Beiromvand et al, 2017;Figatt et al, 2017;.…”
