Participants pose for a group photo after the launch of the MakSPH study on possible lead exposure from domestic cookware in Kampala, held on 11 June 2026 at the ResilientAfrica Network in Kololo.
Across Kampala, families use saucepans, cooking pots, frying pans, kettles, and pressure cookers every day. Makerere University School of Public Health is now investigating whether some of these items may expose households to lead, a toxic heavy metal that can enter food during cooking if contaminated materials are used to make them.
The year-long study, titled “Assessment of Lead Contamination in Domestic Cookware, Supply Chains, and Exposure Pathways in Informal Settlements of Kampala,” was launched on 11 June 2026 at MakSPH’s ResilientAfrica Network (RAN) in Kololo. Supported through the Lead Exposure Elimination Project (LEEP), with funding from Bloomberg Philanthropies, and led by Mr. Douglas Bulafu, Mr. Tom Okade, and Dr. Rawlance Ndejjo, the study will assess total and leachable lead levels in commonly used cookware, map how the products are sourced, distributed, and sold, and identify feasible interventions to reduce household exposure to lead.

Today, lead remains a major and preventable public health concern globally. WHO reports that no level of exposure is known to be without harmful effects and estimates that lead exposure contributes to more than 3.5 million deaths worldwide, mainly through cardiovascular effects. Children and women of child-bearing age are said to be especially vulnerable, with exposure linked to impaired brain development, reduced learning ability, harm to unborn children, high blood pressure, cardiovascular disease and kidney damage.
In Uganda, lead exposure concerns also extend to household products and informal markets. Aluminium pots and saucepans, particularly low-cost locally fabricated items, may be made from recycled scrap metal. If contaminated materials are used, lead may leach into food during cooking or other food-contact use, creating a possible route of exposure in homes.
During the launch, Assoc. Prof. David Musoke, Head of MakSPH’s Department of Disease Control and Environmental Health, underscored the importance of involving stakeholders throughout the research process. He said engaging stakeholders from the generation of research ideas to implementation and dissemination helps ensure findings do not remain within the University but are translated into evidence that can inform policy, practice, and community action.
“We engage with stakeholders throughout the research process, from developing ideas and designing projects to implementation and dissemination,” Dr. Musoke noted. “I am pleased that this workshop brings together policymakers, the Ministry of Health, non-governmental organisations, Kampala Capital City Authority, academia, staff and students. This helps ensure that research findings do not remain at the University but are beneficial to our stakeholders.”
Assoc. Prof. David Musoke delivers remarks during the study launch, emphasising sustained stakeholder engagement to ensure research findings inform policy, practice and community action.
He observed that the study was timely, as it addresses an important yet under-examined public health concern, arguing that while lead exposure from paint, pipes and drinking water has received considerable attention, exposure through cookware remains less understood despite its widespread use in many households. He added that the new research builds on MakSPH’s broader work in disease control and environmental health and will generate critical evidence to inform action on lead exposure risks in Uganda. Dr. Musoke also commended the study team for initiating this work.
Previously, MakSPH researchers Mr. Abdullah Ali Halage, Mr. Tom Okade, Dr. James Muleme and Dr. Juliet Kiguli, together with Mr. Ahmada Zziwa and Mr. Robert Mugabi, assessed knowledge, perceptions and practices related to heavy metal contamination and health risks among residents living near Kiteezi in Kampala, Katikolo in Mukono and Nkumba in Entebbe. The study, done in 2024, reached 505 residents and captured community and frontline perspectives from people living and working around the dumpsites. It showed how daily contact with dumpsite environments may expose communities to toxic heavy metals such as lead, arsenic, cadmium, and mercury through soil, water, air, food crops, animal products and waste-handling practices.
Evidence from the study, funded by the Government of Uganda through the Makerere University Research and Innovation Fund (MakRIF) and disseminated on 26 June 2025, showed that heavy metal exposure risks around the three municipal dumpsites within the Kampala Metropolitan Area were shaped by both environmental conditions and community behaviour.

Although residents lived near dumpsites where waste can release heavy metals into soil, water and food chains, 76.4 per cent could not define heavy metals, and only 45.9 per cent had adequate knowledge of contamination and related health risks. Gaps extended to daily exposure pathways, with 38.4 per cent unaware that vegetables grown near dumpsites may contain high heavy metal levels and 39.8 per cent unaware that milk or meat from animals grazed near dumpsites may also be contaminated. More than half viewed dumpsite soils as fertile, 50.7 per cent considered such milk safe, and 51.3 per cent believed dumpsite waste could be used as manure.
The study recommended stronger risk communication, environmental monitoring, safer land-use enforcement and community education. The work on lead in domestic cookware now extends this focus from dumpsite-related heavy metal exposure to a possible household pathway. Mr. Douglas Bulafu, an early-career researcher and Principal Investigator of the study, said the team will examine whether commonly used cooking pots, saucepans and related utensils contribute to exposure, and generate evidence to guide safer cookware use, standards and market oversight.
“Lead contamination has been documented from sources such as paint, fuel and air pollution, but less attention has been given to cookware as a potential pathway of exposure. That is the gap this study seeks to address,” Mr. Bulafu said. “We focused on Kampala because it has many informal settlements, small-scale cookware workshops and a large consumer market where low-cost cookware is widely produced, sold and used. When people buy these products, they often do not know where they were made, what materials were used, or whether they contain lead. The supply chains are also poorly understood, meaning households could be exposed without knowing.”
Mr. Douglas Bulafu, Principal Investigator, speaks during the launch of the MakSPH study on possible lead exposure from domestic cookware in Kampala, highlighting the need for evidence to guide safer cookware use, standards and market oversight.
The study will use a cross-sectional, mixed-methods design to connect laboratory evidence with supply-chain realities in Kampala’s informal settlements. The team will purchase about 100 cookware samples from open-air markets, roadside vendors, retail shops and supermarkets in Kisenyi, Katanga, Bwaise, Namuwongo, Banda and Kasubi, test them for total and leachable lead, and conduct about 30 key informant interviews across the supply chain to understand how cookware is sourced, produced, distributed and used.
Findings will be validated with stakeholders and used to identify feasible interventions, including stronger regulation and enforcement, raw-material control, better manufacturing practices, market surveillance and consumer awareness. The evidence is expected to support standards development, product testing, policy uptake, safer manufacturing practices and public guidance on cookware choices, helping reduce household exposure to lead and associated health risks.
Speaking on behalf of the Ministry of Health, Dr. Didacus Namanya, a health geographer and environmental health expert, welcomed the study, saying scientific evidence on lead exposure is critical because public health decisions can have lasting consequences for life and wellbeing.
Dr. Namanya implored the research team to ensure the evidence from the study informs decisions beyond academia, shaping policy, strengthening public health practice and guiding practical measures to reduce lead exposure in communities. He emphasised that research should not remain in the “ivory tower” but reach decision-makers and the public, so that evidence from the study translates into policy, practice and stronger protection for communities.

Despite a morning downpour, the two-day 92ndMakerere University Guild Annual Medical Camp successfully commenced on September 17, 2026 with a launch at the Freedom Square.
The Launch marks a strategic partnership between the Ministry of Health and higher education institutions to advance physical well-being and awareness of students from public and private universities.
Presiding over the event, the Minister of State for Health (General Duties), Hon. Anifa Kawooya Bangirana, launched the intensified testing and active case finding for Malaria, HIV/AIDS and Sickle Cell Disease.
Ministry officials emphasized that laboratory screening and diagnostic testing are critical entry points for early detection, linkage to care, appropriate clinical management, surveillance and prevention, and the Ministry of Health pledges full support to strengthen these services across universities nationwide.

Held under stewardship of the Makerere University Dean of Students office, the camp offered a comprehensive suite of health services to the student body and the wider community. Attendees had access to the following services:
General and Specialist Consultations
Sickle Cell, Malaria RDT and HIV Screening
Eye Care and Laboratory Diagnostics
Free Essential Medicines
Reproductive Health Counseling
Mental Health Counseling
While addressing the attendees, Hon. Kawooya emphasised that health is synonymous with national economic productivity.
She guided the youth to prioritise well-being, and avoid living in denial for it is the first step to refusing help. This will help build a firm foundation for any future contributions to national development.
Hon. Anifa Kawooya accompanied by Guild Health Ministers from various institutions tours the exhibition.
The Minister further warned students against risky behaviours, including substance abuse and sexual immorality, which she described as poisonous.
She advocated for responsible reproductive health practices, urging students to utilise resources available to protect themselves for the future.
Why you should Know Your Status
Prof. Charles Olaro, who is the Director General of Health Services at the Ministry of Health, Uganda reflected on his time at the university during the peak of the HIV epidemic, recalling a visit from the late Bongole Lutaya.
He noted that today’s youth have not witnessed the severity of the AIDS due to the availability of care and ARVs, which can create a false sense of security.
“People are in care and you have not seen the real slim disease. You have not seen it”
Prof. Charles Olaro.
He added that some attending are products of mothers that undertook prevention of mother-to-child transmission of HIV, and they gave birth to negative children. But now when we are grown up, they are reckless with their sexual life.
Prof Olaro summarized his remarks by noting that health is an irreplaceable asset and that decisions made today have significant future ramifications. They urge the audience to take the opportunity to know their status, whether for HIV or sickle cell disease, as this is the essential entry point for care and life planning.
Benefits of knowing your status:
It serves as the entry point for receiving necessary care.
It allows for better life planning.
It enables individuals to manage other aspects of their lives effectively.
It prevents future health complications.
Genetic Awareness and Blood Donation
Associate Professor Richard Idro the Deputy Principal of the Makerere University College of Health Sciences (MakCHS) emphasised the importance of seeking appropriate information with a focus on genetic awareness. He advised the students to know their status before marriage to prevent passing on genetic conditions.
“One day when you fall in love, you know that preferably you should not marry somebody who is also carrying a certain gene.”
Prof. Richard Idro.
He then delved into the importance of treating HIV and clearing malaria parasites, which he addressed exhaustively.
From this, Dr Idro’s focus turned to blood donation where he acknowledged a number of people that had already participated in the exercise at the Uganda Red Cross Society tent.
“I see the Red Cross at one corner. As we passed there, 36 people had donated blood. Although, gentlemen, I saw very few of you donate blood.”
He concluded by challenging the young men present and reminding them that they can donate blood up to four times a year and still remain healthy.
Empowering Ambassadors of Global Health Awareness
The Ministry of Health called upon the students attending the camp to serve as ambassadors for global health awareness in their respective institutions.
The Executive Director/Commissioner National Health Laboratory and Diagnostic Services (NHLDS), Dr. Susan Nabadda Ndidde advised the students to make sure that they mobilise and intensify testing for all these diseases.
Dr. Susan Nabadda Ndidde.
“We will work with you as a Ministry to provide the tests to make sure that we know your status and prevent these diseases in time.”
She wrapped up her message by thanking Makerere for allowing the Ministry of Health to partner on this cause and urged the students to embrace this opportunity and make sure they leave after establishing their status.
By bringing these critical services directly to campuses, the government fosters a healthier, and more informed generation capable of driving Uganda’s future development.
Students Appreciate the Medical Camp
According to Denise Kainomugisha, the Chairperson of the Makerere University School of Public Health (MakSPH) and Vice Minister of Health in the 92nd Guild, the Camp served as a vital platform for capacity building.
92nd Guild Health Minister Hon. Wamezaya Ebenezer (R) and his Vice Hon. Denis Kainomugisha (L).
“The screening, the testing, the sports science, was all handled by the student volunteers under supervision” she confessed.
She also explained that the camp extended to broader public health goals and additionally fostered leadership and collaboration among students, who were encouraged to work together to address community health needs.
Concluding her remarks, Kainomugisha expressed gratitude to the respective partners for providing both financial support and the opportunity for students to take on active roles throughout the Medical Camp.
Students and researchers from Makerere University and other institutions pitched 12 innovations addressing challenges in healthcare, clean energy, agriculture, waste management and community resilience during the inaugural Falling Walls Lab Kampala, held at the School of Public Health Auditorium, Makerere University.
The competition brought together emerging innovators to present solutions to practical challenges through a three minute pitch, followed by questions from a panel of judges.
Modelled on the Falling Walls format that originated in Berlin, the event required each participant to identify a “wall” a problem or barrier, and demonstrate how their innovation seeks to break it down.
Mudhasi wins with newborn jaundice screening device
Andrew Mudhasi of Makerere University emerged as the overall winner with a score of 90 per cent for a low cost medical device designed to improve newborn jaundice screening across different skin tones.

Mudhasi explained that the device uses optical sensor technology and a skin tone targeting algorithm to provide a rapid reading, with the aim of helping nurses and clinicians identify jaundice more efficiently.
During questions from the jury, Mudhasi said the device had not yet been tested on actual babies but had undergone laboratory testing using simulated skin tones.
He reported an accuracy rate of 94 per cent when the device was compared with laboratory spectrophotometers.
The innovation is intended initially for use in clinics and hospitals, with Mudhasi saying the team is also considering a version that could eventually allow mothers to screen babies at home.
Mudhasi’s innovation has previously received recognition at the African Business Concept Challenge and the iF Design Student Award, according to his presentation.
Rhonda’s innovation tackles diaper waste
Rhoda John of the University of Nairobi emerged in second place with 89.6 per cent for an innovation addressing the problem of used diaper waste.
Rhondah John pitches her innovation repurposing diaper waste into soil moisture retention
Under the theme “Breaking the wall of diaper waste and drug soils,” Rhonda explained that her team extracts sodium polyacrylate, the absorbent polymer found in diapers, and replaces the sodium with potassium.
The resulting potassium based superabsorbent material is designed to act as a “water battery” in soil by absorbing and retaining water for plants during dry periods.
John said testing showed a 99 per cent increase in germination and a 23 per cent increase in drought resistance.
The innovation also seeks to reduce the amount of used diapers ending up in landfills and the environmental effects associated with their decomposition.
During the question and answer session, John explained that her team was working with government environmental officials in Nairobi on a pilot collection system to address the challenge of gathering used diapers at scale.
Mahera takes third place with herbal peptic ulcer treatment
Stuart Mahera of Makerere University finished third with 86.2 per cent for a herbal formulation targeting peptic ulcers.

Presenting under the theme “Breaking the wall of Nature and Modern Medicine,” Mahera argued that conventional treatment for peptic ulcers can involve multiple medicines and may be associated with side effects and antimicrobial resistance.
His proposed formulation, MARAC capsules, is intended as a monotherapy, combining properties required for peptic-ulcer treatment in a single capsule.
Mahera said his team had carried out quality control work, including characterisation and dose quantification, and had conducted preclinical trials on laboratory mice.
He also told the jury that an application had been submitted to the National Drug Authority as the team awaits the next stage of the regulatory process.
According to Mahera, the proposed seven day treatment would cost about Shs21,000, compared with the existing 14 day treatment approach.
Innovators present solutions to practical challenges
The remaining presentations covered a wide range of challenges.
Esther Nakungu of Utamu University presented Agri-Track, a digital record keeping solution intended to improve visibility, accountability and management of farm operations and financial information.
Dr. Jimmy Chachiga, a Makerere University participant, presented a solar photovoltaic cooker with a heat storage system designed to provide a cleaner and more reliable cooking option during both sunny and non sunny periods.
His presentation focused on reducing dependence on biomass fuels and addressing the challenges associated with intermittent solar energy.
Abdul Noor Luttamaguzi, a PhD student and senior government fisheries officer, presented a mobile application aimed at helping fish farmers and extension officers report, track and manage disease outbreaks.
Henry Duke Tamale presented a herbal cream targeting antibiotic resistant biofilm infections associated with diabetic foot ulcers.
Marvin Seruwu proposed adapting existing near infrared brain monitoring technology to help detect extra-axial brain bleeds in health facilities where access to CT and MRI equipment is limited.
His proposal seeks to repurpose existing technology towards a diagnostic need that could be particularly important in settings where advanced imaging facilities are not readily available.
Kennedy Kisame presented a poultry alert and diagnosis system combining satellite weather information with computer vision disease detection. The proposed system could be accessed through a smartphone application, SMS or USSD, making it potentially usable by farmers with limited internet access.
Frank Atwiine proposed a solar powered mobile diagnostic van designed to bring ultrasound and other diagnostic services closer to rural communities.
Johnson Makmot, a software and blockchain developer, presented a platform that combines GPS tracking and blockchain-based tokens to incentivise and verify plastic-waste collection in Kampala.
Dr. Nelson Ndugu, from a partner university, presented an artificial intelligence tool designed to translate agricultural research publications into local Ugandan languages and generate voice notes for radio-based extension delivery.
The final presentation came from Dr. Juliet Akola, a Ugandan post doctoral researcher at Mangosuthu University of Technology in South Africa.
Akola presented a community digital resilience initiative focused on mapping risks in Kampala’s informal settlements, including flooding, fire, poor sanitation, waste management and inadequate infrastructure.
Her proposal seeks to combine local community knowledge with geographical information systems and link identified risks to action plans involving municipalities and other stakeholders.
Nawangwe calls for more investment in innovation
Closing the event, Prof. Nawangwe congratulated all the participants and described their presentations as an important beginning for Makerere University, Uganda and the wider region.
Vice Chancellor, Prof. Banabas Nawangwe giving his remarks
Drawing on his experience attending the Falling Walls conference in Berlin, the Vice Chancellor said initiatives of this nature are important because innovation will play a major role in determining the future of countries.
He encouraged participants to make their pitches more precise by clearly identifying the problem they are addressing, explaining their proposed solution and demonstrating what they have already achieved.
Prof. Nawangwe also welcomed the participation of innovators from other universities and countries, noting that the Kampala event had attracted participants beyond Makerere.
He thanked the Africa Office of the Falling Walls Foundation for its role in bringing the initiative to Makerere and encouraged continued support for innovation.
The Vice Chancellor further linked innovation to Uganda’s growing youth population and the need to develop home-grown solutions to address challenges such as youth unemployment.
The inaugural Falling Walls Lab Kampala ultimately provided a platform for innovators to move ideas beyond the classroom and laboratory and demonstrate how research, technology and creativity can be applied to challenges affecting communities.
