“…may be caused by organic fertilization, as producers reported using cattle manure as fertilizer. In another study by Pinto et al (2018), which analyzed the level of contamination by parasitic structures in lettuce samples commercialized in street markets in the city of Jardim, Ceará, 80% of the samples were reportedly contaminated by helminth parasitic structures.…”

Parasitological Evaluation of Lettuce Served in School Meals at a Federal State School in Rio De Janeiro, Brazil

The Brazilian “National School Lunch Program” (PNAE) must provide healthy food for students in public primary education. Thus, it is necessary to ensure both nutritional and parasitological quality, reducing health risks. Vegetables must be clean, presenting no parasites and larvae, according to Brazilian legislation. Lettuce (Lactuca sativa L.) is one of the favorite vegetables among students, and is eaten raw in salads. This paper aims to evaluate the parasitological quality of lettuce served in school lunches. 72 samples of leaf lettuce, 36 fromconventional agriculture (CA) and 36 from family agriculture (FA), were analyzed. Half the samples in each group were sanitized by immersion in a sodium hypochlorite solution, with 2% active stabilized chlorine for 10 minutes (n=18/each) and half were not sanitized (n=18/each). Parasite load evaluation was performed by two methods in each subgroup: spontaneous sedimentation (SS) and sedimentation by centrifugation (SC). The parasite frequencies found were evaluated by the chi-squared test. Medically relevant parasites identified were helminths (Strongyloides stercoralis, Ascaris lumbricoides and Hookworms) as well as protozoa (Balantidium coli and Entamoeba coli). 44.6% of the FA samples presented some form of parasite by SS evaluation and 33.4% by SC evaluation; 66.7% of the CA samples presented parasites by SS evaluation, and 44.5% by SC evaluation. No significant differences were noted between the FA and CA groups in either technique. No parasites were found in any of the sanitized lettuces, regardless of the subgroup or technique applied. These results evidence theimportance of adequate training and guidance for vegetable growers, food handlers as well as the general population regarding proper hygiene of lettuce leaves prior to consumption.

“…As parasitoses são doenças relacionadas com a falta de higiene, ausência de saneamento básico e de água tratada (Pinto et al, 2018). As políticas públicas existentes precisam ser consistentes e envolverem educação em saúde, para que amenizem esse tipo de patologia (Lins et al, 2016).…”

Intestinal parasitosis is caused by endoparasites that cause damage to the health of the affected person. These diseases, mainly linked to the conditions of hygiene and basic sanitation, can interfere with the performance of schoolchildren. The objective of this study was to carry out health education actions on intestinal parasitosis with 75 students in the second year of high school in the State of Pará, Brazil. Actions were carried out: school cleaning campaign; manufacture and organization of garbage collectors; collection of hygiene materials; lecture on parasitosis; Creation of cleaning duct: construction of a manual and didactic game. Two stages of parasitological examinations of feces were carried out on the students. The first stage was carried out before the prevention and treatment actions and the second after six months. A pre-test questionnaire (before the activities) and post-test questionnaire (after the activities) were applied. In the first stage of examinations, there was a prevalence of 53% of parasitic infestations in students. After the actions, there was a reduction to 25%, demonstrating that the treatment with dewormers and the actions developed contributed to the reduction of infestations, which shows the effectiveness of direct actions involving students to control these diseases.

“…The detection of parasitic structures in leaves and vegetables demonstrates the potential carrier parasites to humans and, consequently, a risk to public health (Pinto et al, 2018). Draeger et al (2019) have suggested that outbreaks triggered by intestinal parasites often do not have the determination of the parasite specie, in view of a low percentage of species identification (between 25% and 30%) was verified for the cases reported from 2016 to 2017.…”

“…The occurrence of parasitic structures in lettuce produced in Brazil was analyzed in five regions, in farms of production, commercialization area, and their consumption habits, as well as in farm production (Barbosa et al, 2016), horticulture fair (Tiyo et al, 2016), open markets (Medeiros et al, 2019;Ramos et al, 2019;Pinto et al, 2018;Oliveira et al, 2016), supermarkets (Almeida et al, 2016), bistro (Silva et al, 2017), and two or more types of leaves and vegetable commercialization (Ambrozim et al, 2017;Luz et al, 2017;Trevisan et al, 2017;Brauer et al, 2016;Nogueira et al, 2016;Silva et al, 2016). These mentioned studies were carried out in the Southeast, North, Northeast, South and Midwest regions of Brazil, using diagnostic techniques of spontaneous sedimentation or centrifugal -flotation, or the quantitative FLOTAC technique, based on the flotation of eggs and cysts (Pedroso et al, 2020, Ramos et al, 2019.…”

This study aimed to investigate the occurrence of parasitic structures in curly lettuce (Lactuca sativa L.) sold in food stalls open markets in Cuiabá city, in the Brazilian state of Mato Grosso (MT). For this purpose, 50 samples were evaluated using spontaneous sedimentation and centrifugal flotation methods. These techniques showed positivity in 96% (48/50) and 78% (39/50) of the samples, respectively. The sedimentation method was statistically (p ≤ 0.05) more effective in detecting parasitic structures of the pathogens as Entamoeba histolytica, Ascaris spp., Strongyloides spp., Larvae and Hookworm eggs, when comparing both methods. However, these methods did not differ significantly for the detection of Giardia lamblia. Ascaris spp and Entamoeba coli occurred in 64% (32/50) and 46% (23/50) of the positive samples, respectively, with the highest percentages observed. The occurrence of Blastocystis spp., Fasciola spp., Dipylidium caninum and Ascaris lumbricoides revealed detection exclusively by the spontaneous sedimentation method, while Iodamoeba butschlii and Enterobius vermicularis were detected by centrifugal– flotation procedure. These results could reinforce the need to use methods based on sedimentation and the fluctuation of parasite structures in the analysis of lettuce. The presence of parasites in lettuce by fecal origin, with recognized pathogenicity, represents a risk to consumer health and demonstrates a deficit in good agricultural practices in the production, distribution and commercialization of lettuce.
