“…This study analyzed 75 samples of fresh lettuce obtained from the two largest wholesale markets ("Mayorista" and "Modelo") and the main open-air market ("Feria") in Jauja Province, Junin Region, in the central Peruvian Andes (altitude 3400 m, latitude 11 • 46 S, longitude 75 • 30 W). This is the second most populated province in the region and is endemic for many parasitic zoonoses, such as fasciolosis, echinococcosis, sarcocystosis, cryptosporidiosis, and other zoonotic protozoan diseases [23][24][25]. In this agricultural region, daily temperatures range from 0 to 23 • C and the climate is dry, with two distinct seasons: a rainy season from November to April and a dry season from May to October.…”

Peru is currently one of the world’s leading culinary destinations, whose world-renowned cuisine uses vegetables, mainly lettuce, as frequent ingredients. Vegetable consumption is promoted worldwide as a part of a healthy diet. However, vegetables, more frequently lettuce, have been implicated as a vehicle of infection for several foodborne parasites. This study aimed to determine the presence of potentially pathogenic parasites in lettuce marketed in the Central Andes of Peru. A total of 75 lettuce samples were collected from the two largest wholesale markets and the main open-air market in Jauja province, in the central Peruvian Andes. The province of provenance (coast vs. highlands), lettuce variety (“curly-leaf”, “iceberg”, and “butter”), and type of market were recorded. The samples were microscopically examined for detection of parasitic life forms using standard parasitological methods including direct slide smear, Lugol’s iodine staining, and Modified Ziehl–Neelsen staining. The overall positivity of parasitic contamination in lettuces was 45.3% (CI 95%: 34–56.6%). Cryptosporidium spp., Isospora belli, Giardia lamblia, Balantidium coli, and Entamoeba spp. were detected in twenty-six (34.7%), six (8%), four (5.3%), two (2.7%), and two (2.7%) lettuces, respectively. I. belli was found in a significantly (p < 0.01) lower proportion in the “butter” variety, and significantly (p < 0.05) higher contamination with G. lamblia was found in lettuce sold at the open-air market. B. coli, G. lamblia, and E. histolytica/E. dispar/E. moshkovskii were detected only in lettuce from the highlands (Tarma province). This study provides important data for health authorities to develop food safety programs. This information is also of interest to the international community because of the increased visibility that Peru has gained as a tourist destination.

Sarcocystis is a threat to food security in the Peruvian Andes. The Sarcocystis species that forms microcysts in the myocardium of alpacas is S. masoni n. sp. (known as "S. lamacanis"). There is a lack of current studies estimating the prevalence of this parasite in alpacas, although this information is crucial for the control and prevention of sarcocystosis. The aim of this study was to determine the frequency and cyst density of Sarcocystis masoni n. sp. in the myocardium of alpacas in Huancavelica, a province of the Andean region of Peru. Myocardial samples for histological analysis were taken from 104 alpacas slaughtered in an o cial abattoir in the area. All alpacas (100%) presented this parasite. About 44% (95% CI: 34.5-53.5%), presented from 31 to 45 microcysts per mm2 of myocardial histological slide (cyst density). Cyst density was signi cantly higher (p<0.05) as the age of the animals increased. In addition, cyst density was signi cantly higher (p<0.05) in 4-and 5-years-old males compared to females of the same age. These results con rm that myocardial sarcocystosis is highly endemic in alpacas in Peru.
