6.D. Skills building seminar: Family Vulnerability Scale: Why and how to use at Primary Health Care to promote health equity?

Abstract Family vulnerability encompasses multiple perspectives that are interconnected with the health needs of each family member. Families experiencing vulnerability face heightened risks of poor health outcomes. Nonetheless, these vulnerabilities are further compounded by systemic inequalities within healthcare systems, where biological or clinical factors are exclusively considered to organize and/or prioritize access, especially given the scarcity of valid instruments to measure family vulnerability. Primary Health Care (PHC) plays a pivotal role in addressing health inequalities, especially considering its bond with community. From this context, the Family Vulnerability Scale for Brazil (EVFAM-BR, in Portuguese) was developed and validated, been composed of 14 items about four dimensions (income, healthcare, family and violence) (2019-2023). By reducing the gap between science and practice, the implementation process of EVFAM-BR was started at the same year the scale was validated (2023). First, it occurred at 14 PHC services in São Paulo (Southeast Region, Brazil) and second, since 2024 has been implemented at Boa Vista (North Region, Brazil). Also, between 2024 and 2026, the implementation of EVFAM-BR is expected to take place in other Brazilian states participating in the third phase of the PlanificaSUS project, which is developed aiming to support State health departments to implement the Health Care Planning method to organize and integrate PHC and specialized outpatient care based on population health care needs. At this stage, capacity building is needed to align the concept of family vulnerability and to train PHC managers and health professionals on how to apply and use results from EVFAM-BR. This training has already been performed for around 1,000 health professionals from two different regions of Brazil, including managers, Community Health Workers, nurses, and physicians. The present workshop proposal aims to disseminate the EVFAM-BR and to offer the EVFAM-BR experience. It proposes knowledge transferring throughout participants engagement at three activities. Activity 1) “Family Vulnerability: From concept to a scale validity and application”: it is designed to engage participants to discuss about the family vulnerability concept and applicability at PHC, and to discuss on how EVFAM-BR implementation process has been occurring at Brazil and how can be tailored to other contexts. Activity 2) “Role Play: Practicing EVFAM-BR”: Two cases will be used for role play dynamics that will take place in trios, in which one will represent the community health worker, another will be the patient and the third will be the observer. Activity 3) That ones that assumed observer role will share their experiences of using EVFAM-BR. Finally, a discussion will be facilitated based on the participants’ impressions and a review of the main points covered throughout the workshop. Key messages • Family vulnerability stratification (through EVFAM-BR) is essential to plan services achieving equity and qualified population-based care management and to qualify patient approach and care. • Family Vulnerability Scale (EVFAM-BR) training represents efforts to reduce the gap between research and practice and contributes to address social determinants of health on healthcare.

Lazer Boa Vista: Web Application of Leisure Spaces in Boa Vista/Roraima

Objective: The main objective of this study was to explore and identify the main leisure spaces in Boa Vista/Roraima, and to develop a web application that allows users to access interactive multimedia content with the information researched about the municipality (leisure spaces, equipment and activities). Theoretical Framework: The concept of leisure has changed over the years and is currently defined as moments of fun and relaxation in one's free time from work. Providing accurate and up-to-date information on leisure spaces enables people to access and occupy them quickly. Method: This study is characterized by exploratory research and applied research, as its purpose was to generate a product. After the exploratory research, the neighborhoods with the greatest potential for leisure spaces were defined to make up the web application. Leisure research tools were used (bibliographic and documentary research) and application development tools (the programming language suited to the application's purpose). Results and Discussion: 28 neighborhoods with preserved leisure spaces were found, including 25 types of leisure equipment and 45 types of leisure activities practiced in these spaces. This information was used to create the “Lazer Boa Vista” web application. Originality/Value: This study contributes by gathering and listing the leisure spaces in the municipality of Boa Vista/RR. The relevance of this study stands out for highlighting tourist leisure spaces, collaborating with this area socio-economically, popularizing and disseminating them through digital marketing.

Venezuelan migration to Brazil: teachers and students co-constructing multicultural education inside classrooms

PurposeThis study aims to show the complexities of engagement between students - Venezuelan and Brazilian - and their teachers. This qualitative ethnographic study documents the everyday pedagogies and practices that take place in elementary schools with high levels of refugee and immigrant children. While Brazilian law ensures the basic right to public education, forbidding discrimination based on nationality or immigration status (Lei de Diretrizes e Bases da Educação, 1996), the barriers remain. Through the frameworks of multicultural (USA) and intercultural (Brazil) education, this paper shows how Brazilian teachers and students of Venezuelan and Brazilian backgrounds engage, learn from one another and build welcoming spaces, but also how stereotypes are reinforced inside classrooms and schools.Design/methodology/approachThis qualitative study uses ethnography to understand how recent Venezuelan migratory flow influences Brazilian and Venezuelan children’s educational experiences in elementary education. Participants were Venezuelan (N = 57) and Brazilian (N = 76) children in two elementary schools in the city of Boa Vista. Data sources for the study are school observations in four elementary classrooms (1st and 2nd grade) and semi-structured interviews with caregivers, teachers, administrators and other educators. This paper also collected children’s drawings and writings and documents like curricula, strategic planning, guidelines, policies, grades, reports and any other textual or photographic material made available at the city level.FindingsIn the field of education, there is a critical need for understanding children’s education experiences. This paper focuses on the experiences of teachers and students in two elementary schools in Brazil. This paper focus on two findings: first that teachers promote the learning of Portuguese to show care toward their Venezuelan students. Second, children in the classroom show solidarity with one another and resist some of the more rigid Portuguese-only practices enacted by teachers. This work uses the frameworks of intercultural (more commonly used in Brazil) and multicultural education to inform the analysis.Research limitations/implicationsIn this study, this paper puts these frameworks of interculturalism, multiculturalism, language use and solidarity into conversation to understand the dynamics of two elementary classrooms in the city of Boa Vista, Brazil. While this paper shows the shortcomings of a seemingly multicultural and multilanguage classroom, it also shows how children actively resist the rigidity of teaching and learning in elementary schooling.Originality/valueThis study is a response both to the increasing South–South migration trend in Latin America and its consequences on public education systems. Through multicultural and intercultural lenses, this research highlighted the complexity of interactions within multicultural classrooms by delving into a two-year ethnographic study conducted in Boa Vista, Brazil, focusing on Venezuelan and Brazilian children in two local elementary schools. This paper focused on two main observations this paper refers to as “Teaching Portuguese as a Way of Caring” and “Children's Solidarity Work.” Teachers primarily centered their instruction on teaching Portuguese to migrant children, believing it to lead to quicker integration in the classroom and beyond – thus as a way of caring for their migrant students.

THE CHALLENGES OF EJA TEACHERS

The present work aimed to report the experiences of teachers working at EJA in a school in the municipal network of Boa Vista, Roraima. The need to understand the challenges and practices of teaching methodologies in EJA was addressed. The methodology used was content analysis. The results revealed three categories: Category 1 - Training; Category 2 - Challenges; Category 3 - affectivity, which evidenced the way EJA teachers understand the teaching/learning issues of these students. The investigation pointed out that the lack of implementation of public and educational policies represented by the categories analyzed requires a change of paradigms, as well as physical structure, pedagogical/didactic and human resources. In addition to the issue of teacher training to deal with learning difficulties of EJA students. It is concluded that the pedagogical practices that serve both young and adults need to be renewed, but always considering their prior knowledge for more significant learning.

High serological and molecular prevalence of Ehrlichia canis and other vector-borne pathogens in dogs from Boa Vista Island, Cape Verde

Despite the high global impacts of canine vector-borne diseases (CVBD) due to their wide distribution and zoonotic potential, the current epidemiological situation of CVBD in many tropical and subtropical regions remains unknown. This study examines the seroprevalence and molecular prevalence of Ehrlichia canis and other pathogens causing CVBDs (Leishmania infantum, Dirofilaria immitis, Babesia spp., Anaplasma spp. and Hepatozoon canis) in dogs living on the island of Boa Vista (Cape Verde Republic). Blood samples and infesting ticks were taken from 150 dogs across the island (stray, shelter, and pet dogs). Serum samples were tested using a rapid immunochromatographic test (Uranotest® Quattro) that detects antibodies against E. canis, L. infantum, Anaplasma spp. and D. immitis antigen. Levels of serum antibodies against E. canis were measured using the immunofluorescence antibody test (IFAT). In addition, tick-borne pathogens in blood samples (Anaplasma spp., Babesia spp., Hepatozoon spp., and Ehrlichia canis) were detected by microscopy observation and/or PCR plus sequencing. The seroprevalence of E. canis was extremely high at 82% (123/150), as revealed by both immunochromatography and IFAT. Most dogs returning a seropositive test result (82.92%; 102/123) had antibody titres > 1:1280 but showed no clinical signs or notable laboratory abnormalities. Of the 123 animals testing seropositive for E. canis, 67 (54.47%) also presented antibodies against Anaplasma spp., and 13 (10.56%) showed the presence of Hepatozoon spp. gamonts in the blood smear. Ehrlichia canis infection was detected in 17.1% (25/146) of dogs tested by direct sequencing of polymerase chain reaction (PCR) products. Co-infections were detected in seven of these dogs: four dogs tested PCR-positive for both E. canis and A. platys, two dogs tested positive for E. canis and Hepatozoon spp., and one dog tested positive for E. canis, A. platys and Hepatozoon spp. Rhipicephalus sanguineus sensu lato was the only tick species found infesting the canine study population. The high prevalence of tick-borne pathogens detected in dogs from Boa Vista Island highlights a need for improved control measures designed to prevent the transmission of these pathogens.Graphical

Investigation of Mutations in the crt-o and mdr1 Genes of Plasmodium vivax for the Molecular Surveillance of Chloroquine Resistance in Parasites from Gold Mining Areas in Roraima, Brazil.

Plasmodium vivax causes the largest malaria burden in Brazil, and chloroquine resistance poses a challenge to eliminating malaria by 2035. Illegal mining in the Roraima Yanomami Indigenous territory can lead to the introduction of resistant parasites. This study aimed to investigate mutations in the pvcrt-o and pvmdr-1 genes to determine their potential as predictors of P. vivax chloroquine-resistant phenotypes. Samples were collected in two health centers of Boa Vista. A questionnaire was completed, and blood was drawn from each patient. Then, DNA extraction, PCR, amplicon purification, and DNA sequencing were performed. After alignment with the Sal-1, the amplified fragment was analyzed. Patients infected with the mutant parasites were queried in the Surveillance Information System. Among the patients, 98% (157/164) of participants were from illegal mining areas. The pvcrt-o was sequenced in 151 samples, and the K10 insertion was identified in 13% of them. The pvmdr1 was sequenced in 80 samples, and the MYF haplotype (958M) was detected in 92% of them and the TYF was detected in 8%, while the MYL was absent. No cases of recrudescence, hospitalization, or death were found. Mutations in the pvcrt-o and pvmdr-1 genes have no potential to predict chloroquine resistance in P. vivax.

Improving Water Efficiency in Higher Education Institutions: Contributions From the Boa Vista Campus of the Federal Institute of Roraima

Objective: The objective of this work is to propose recommendations to improve the management of water resources in a federal higher education institution, aiming to increase water use efficiency and promote a culture of sustainability among students and the local community. This can serve as a benchmark for institutions with similar characteristics. Theoretical Framework: Efficient management of water resources is crucial given the growing global challenge of water scarcity, especially in educational contexts, as they consume a lot of this resource and have a commitment to citizen education. The theoretical framework includes concepts related to sustainability, resource management, and educational institution practices.

These implications include recommendations for short, medium, and long-term actions that are replicable to other institutions. Originality/Value: This study contributes to the literature by updating sustainable water management practices in educational environments and offers significant applied contributions to the implementation of effective water management solutions. The relevance and value of this research are evidenced by its potential impact on decision-making by managers of other educational units.

Consumption of Ultra-Processed Foods in the Brazilian Amazon during COVID-19.

A COVID-19 pandemic erupted, causing a global viral pneumonia outbreak, marking the most significant public health crisis of the 21st century. These changes profoundly impacted population health and well-being, leading to shifts in dietary habits. This study aimed to evaluate the consumption of ultra-processed foods in the Brazilian Amazon before, during, and after the COVID-19 pandemic. This is a secondary data analysis study derived from the Surveillance System of Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel, 2019-2021) of the Brazilian Ministry of Health. All statistical analyses were performed using the Stata 17 statistical program in the survey module (svy). We found an increased frequency in the subgroups of consumption of ultra-processed foods in the capital of the Brazilian Amazon region between the years 2019 and 2021. In the cities of Boa Vista and Macapá, there was a significant increase in the consumption of snacks, salty snacks, cookies, and meat products. Boa Vista and Macapá showed an increase in the percentage difference in the consumption ≥5 of ultra-processed subgroups, being 30.4% (p = 0.014) and 53.7% (p = 0.014), respectively. The study indicated an increase in the consumption of ultra-processed foods in the Brazilian Amazon region during and after social distancing.

Using Respondent-Driven Sampling (RDS) to Identify the Healthcare Needs among Women of Reproductive Age Who Migrated from Venezuela to Brazil, 2018-2021.

In 2021, an RDS survey was conducted among Venezuelan migrant women of reproductive age who migrated to two Brazilian cities (Manaus and Boa Vista) from 2018 to 2021. To start the RDS recruitment, we chose seeds non-randomly in both cities. The study variables were age, educational level, self-rated health, pregnancy, migratory status and use of health services. We estimated the prevalence, confidence intervals and homophily effects by variable category. We used a multivariate logistic regression model to identify the main factors associated with healthcare use. A total of 761 women were recruited in Manaus and 1268 in Boa Vista. Manaus showed more irregular migrants than Boa Vista. The main reasons for using health services were as follows: illness, disease prevention and prenatal care. The logistic regression model showed the use of health services was associated with educational level and healthcare needs but not with migratory status. The social inclusion of Venezuelan migrants is extremely relevant, although many challenges must be overcome. The strategy of the Brazilian Federal Government for providing humanitarian assistance to Venezuelan migrants should be expanded to include and facilitate their integration into labor markets, access to healthcare and education, benefiting both migrants and the Brazilian people by reducing social inequality.

Healthcare access, quality and financial risk protection among displaced Venezuelan women living in Brazil: a cross-sectional study

Millions of Venezuelans have been displaced because of deteriorating socio-economic conditions in their country. We examine key domains of universal health coverage among migrant Venezuelan women in Brazil: healthcare access, care quality and financial risk protection. We collected primary data on 2012 Venezuelan women aged 15-49 who migrated to Brazil between 2018 and 2021, in the cities of Boa Vista and Manaus, along with secondary data for Brazilian women. We used linear regression with entropy balance matching to estimate associations between migrant status and healthcare spending, utilisation and quality indicators. Our sample had a mean age of 29.5 years (S.D. 8.9), 64% (1286/2011) of mixed ethnicity, 29% (577/2011) white, 4% (71/2011) black, 3% (62/2011) indigenous and 1% (15/2011) other ethnicities. Compared to Brazilian women, migrant women had 9.5 percentage points (pp) (95% CI: 6 pp-13 pp; p<0.0001) higher catastrophic health expenditure incidence. Migrants were 27 pp (95% CI: 11 pp-43 pp; p=0.0008) more likely to receive healthcare when sought, but 37 pp (95% CI:-45 pp to-29 pp; p<0.0001) less likely to have had a pap smear in the last three years. Migrants were as likely as non-migrants to have received pap smear results within three months (95% CI:-9 pp to 22pp; p=0.39) and clinically appropriate antenatal consultations (95% CI:-10 pp to 40 pp; p=0.23). Migrant women in Brazil have relatively good healthcare access and quality outcomes. Yet a potential backlog of unmet sexual and reproductive healthcare needs and inadequate financial risk protection require policy attention. UK Economic and Social Research Council (ES/T00441X/1).

Evaluating Cumulative Damage Factor (CDF) of 20 Brazilian Airfield Pavement structures using FAARFIELD and BAKFAA

There is a growing concern regarding the structural integrity of Brazilian airport pavements. This concern arises from the fact that they were originally designed to accommodate lighter aircraft during an era of lower traffic. However, with the substantial increase in air traffic and the introduction of heavier aircraft, compounded by the aging infrastructure predominantly built between the 1950s and 1970s, these pavements are now confronted with significant challenges. This research involves collecting data on aircraft characteristics, traffic patterns, and pavement layer properties to update information on the pavement life service of existing Brazilian airfield pavements. Research involves the analysis of determine the Cumulative Damage Factor (CDF) of 20 Brazilian airport runways pavement. Backanalysis of deflection basins obtained from Heavy Weight Deflectometer (HWD) tests is conducted using the BAKFAA software. The FAARFIELD software is then employed to calculate the CDF, incorporating the latest information on aircraft mix and pavement conditions. The study reveals that 65% of the analyzed airport pavements consist of 4 structural layers, with 50% of the structures composed of cement-treated base course layers. Notably, 11 airports exhibit a CDF less than 0.01, suggesting potential overdesigned of pavements for existing aircraft movement. Boa Vista Airport/RR (SBBV) stands out with a CDF of 1.5, prompting recommendations for actions to mitigate pavement degradation. The findings offer valuable insights for future actions, maintenance strategies, and recommendations for the construction of new airports.

Geotechnical field investigations to measure soil resistance on the Boa Vista/RR Western Bypass Highway and solution to embankments on soft soils

Among other challenges, embankments on soft soils have inspired geotechnical engineers, designers and executors to seek challenging solutions. Professor Márcio Almeida, one of the greatest experts on the subject, mentions that these challenges have already resulted in successes and memorable failures in works on soft soils. In general, soft soils are considered to be materials with high plasticity, in some cases rich in organic matter, with Nspt ≤ 4. Thus, brief considerations about soft soils are presented, as well as results with analysis and discussion of geotechnical studies carried out on the Boa Vista Western Bypass Highway (BR 174), in the state of Roraima, with the aim of determining the resistance of soils by means of in situ Vane Tests, in accordance with ABNT NBR 10905: 1989 (MB-3122). The studies consisted of carrying out “Geotechnical Field Investigations” on 11 sections of the highway. Considering the results, it was found that the layers of soft soil in the sections studied have “average” thicknesses that vary from section to section, with minimums close to 2.0 meters and maximums that exceed 6.0 meters. In addition, the existing embankments of the old road, located on the sections studied, indicate the presence of soils with low bearing capacity under the body of the embankments. In addition to the studies, solutions are proposed for the embankments on soils with low bearing capacity.

Intimate geographies of precarity: Water infrastructure and the normalisation of militarism in humanitarian intervention

The recent increase in Venezuelan migrants and refugees to Brazil has prompted a humanitarian response coordinated by multiple government agencies and inter/national organisations. This coordination effort sits under the umbrella of the Operation Welcome task force, in which the military is heavily involved. Situated in the northern state of Roraima, bordering Venezuela, this article explores one particular site of humanitarian care: a set of Water, Sanitation and Hygiene (WASH) facilities located in the capital city of Boa Vista. Here, I investigate the militaristic design and processes of the shower block, which is available to Venezuelan refugees and migrants who are living without adequate shelter. In doing so, this paper argues that the normalisation of militarism in humanitarian intervention (re)produces exclusion and precarity for those accessing spaces of care. By understanding the water infrastructure of the site as an infrastructure of containment, this research shines light on the everyday, often invisiblised implications of migration governance that occur at the micro-scale. In particular, it highlights the conditions of slow and symbolic violence that are embedded within the military-humanitarian response.

Population based screening for osteoporosis in men among 40 and 80 years in the brazilian state of Roraima"

The main objective of this study was to conduct population screening for osteoporosis in men between the ages of 40 and 80 in the Boa Vista, the capital of the Brazilian state of Roraima. The population study conducted in this study was basically based on the Fracture Risk Assessment Tool (FRAX®) nomogram model proposed by the World Health Organization (WHO). Specifically, the current work focuses on (i) analyzing the serum concentrations of calcium, vitamin D and total testosterone in relation to the risk of bone event by the FRAX® nomogram and (ii) correlating cardiovascular risk by calculating Framingham score with the FRAX® nomogram. This cohort, and cross-sectional study involves both quantitative and qualitative data obtained in the field from 380 patients. The data obtained were compared to the pre-existing data collected through different bibliography. For the sampling, a cluster method was utilized. Patients with immediate need of health services were referred to the state hospital of Coronel Mota, Boa Vista. This project was approved by the Ethical Committee (number: 50207115.7.0000.5301). While commuting to work or travel around found to be the major reason of the fractures, we observed that older people and people who were involved in physical activities inside a gymnasium had considerably high at risk of fractures. FRAX and TBS femur score (Trabecular Bone Score) was higher for people with fractures. People having lumbar osteopenia and femur osteopenia had higher risk of TBS femur fractures while people having lumbar osteoporosis had higher risk of TBS (femur and hip) as well as FRAX femur factures. All the data obtained in this study were analyzed using SPSS version 21 and a p value of ≤0.05 was considered as statistically significant. Key risk factors for fracture include increased age, physical activities in a gymnasium, lumbar and femur osteopenia and lumbar osteoporosis.

General evaluation of the distribution and commercialization cycle of bananas at the main fairs in Boa Vista - RR

In Roraima, banana cultivation is a significant socio-economic activity aimed at catering to both the domestic and regional markets. The banana-producing region (Musa spp) is concentrated in the southern part of the state, encompassing the municipalities of Caroebe, São João da Baliza, and Rorainópolis. Thus, the objective was to assess fruit damage and investigate severity and causes. The cultivars selected for the study were ‘Pacovan’, ‘Prata’, and ‘Missouri’. Five markets were visited for the study, with eleven points of sale sampled at each market. At each sampling point, newly arrived batche (bunches) was collected at three distinct times. The variable studied was the incidence of fruit damage at different ripening stages (type 2 and type 7). Data collected visually were subjected to Likert analysis and descriptive statistics. The results showed that mature bananas exposed directly on tarpaulin exhibited severe mechanical damage, such as abrasions and cuts due to direct contact with the rough surface of the tarpaulin and stacking during transport. Mature fruits transported in cardboard boxes had a lower incidence of damage and also served as a display for marketing. Mature green fruits were also affected during transport, with greater impact when in plastic bags or plastic boxes due to irregular and pointed surfaces. In the case of green-mature fruit, the damage incurred was less severe compared to mature fruit.

Migration process of Venezuelan women to Brazil: living conditions and use of health services in Manaus and Boa Vista, 2018-2021.

The last decade saw the emergence of a new significant migration corridor due to the mass migration of Venezuelans to neighboring countries in South America. Since 2018, Brazil became the third host country of Venezuelan displaced populations. Little is known about how migratory processes affect needs, access to social programs, and public health services of migrant women. The goal of this study is to shed light on the socio-economic profile, living conditions, and use of health services of Venezuelan migrant women in two main reception cities in Brazil. A survey was conducted using respondent-driven sampling (RDS) in the cities of Boa Vista (Roraima), and Manaus (Amazonas). The study included 2012 Venezuelan migrant women aged between 15 and 49 years old who migrated from Venezuela to Brazil between 2018 and 2021. Relative prevalence was calculated, and the χ2 test was used to analyse the homogeneity of proportions. All analyses considered the complex sampling. The main reasons for migrating relate to difficulties obtaining food (54%) and accessing health services (37.8%) in their country of origin. They were young and mixed race (65.7%) and had high school education (69.9%). In Manaus, 3.7% of the interviewees declared that they had no family income in the last month, while in Boa Vista, it was higher (66.2%) (p-value < 0.001). Almost one-third of them sought health care in the last 15 days, and 95% of them received care. The residents of Boa Vista arrived more recently and family income and access to paid work improved with time of residence in Brazil. Given the increasing flow of Venezuelan migrants crossing to Brazil, a reception system was established for the provision of food, shelter, access to health services, and income transfer programs to migrants. This was the case despite high unemployment and poverty levels and income inequality, particularly in the city of Boa Vista. However, the majority had legal migrant status and had access to the public and universal healthcare system in Brazil (SUS). The use of the SUS was similar in both cities, acting as a buffer for the differences in opportunities offered.

Adulteration, conformities of packaging and labeling of honey sold in the free markets on the Boa Vista city, Roraima, Brazil

O mel contém açúcares em alta concentração provenientes do néctar das flores, de nectários extraflorais ou de exsudados de inseto. No entanto, o mel pode apresentar adulterações variadas relacionados à adição de ingredientes de baixo valor comercial. Este trabalho teve como objetivo verificar possíveis adulterações em amostras de mel comercializadas em feiras livres na cidade de Boa Vista, estado de Roraima, por meio da análise polínica, sensorial e pela precipitação de proteínas na reação de Lund. Também foram avaliados o acondicionamento e a rotulagem. Foram adquiridas 31 amostras comerciais de mel de Apis mellifera em 06 feiras livres. Das amostras analisadas 20 (64,5%) apresentaram resultado negativo para reação de Lund, ou seja, consideradas adulteradas e 11 (35,5%) mostraram resultado positivo, não adulteradas. Onze amostras de mel não continham pólen. Seis amostras foram consideradas melato de Acacia mangium, sete como mel silvestre e duas como um mix de mel silvestre e melato de A. mangium,. Quanto a embalagem, três amostras estavam acondicionadas em frascos de vidro, as demais em garrafas plásticas, na maioria tipo PET. Somente 11 embalagens possuiam rótulo, mas nenhuma atendeu as exigências da legislação em vigor. Seis amostras rotuladas foram consideradas adulteradas. Com um elevado percentual de adulteração determinado pela reação de Lund. Um percentual tão alto de adulteração serve de alerta aos órgãos fiscalizadores para combate esse tipo de fraude.
