Ghanaian Scientist Uses Math to Tackle Food Safety Risks in Online Food Delivery Era
Emmanuel Addai, a Ghanaian Ph.D. researcher specializing in Mathematical and Data-driven Modeling of infectious disease and cyber forensics at the University of Arkansas at Little Rock, has co-authored a pioneering study that reveals how the rapid growth of online food delivery services is fueling the spread of food-borne illnesses.
In the peer-reviewed article, Addai and his collaborators developed a mathematical model that incorporates both human and insect populations (particularly flies) to simulate how food safety is compromised during doorstep food deliveries.
The model uniquely uses fractional calculus (Caputo operator) to reflect real-world memory effects such as poor hygiene practices and delayed policy responses.
The study shows that:
• Asymptomatic carriers, delivery personnel, and flies are critical transmission vectors.
• Government interventions such as food safety training for restaurant staff and stricter hygiene enforcement can significantly reduce outbreaks without disrupting food delivery services.
• The model was proven stable and accurate under rigorous mathematical conditions and tested using numerical simulations in MATLAB.
By integrating public health, data science, and mathematical modeling, Addai’s work provides a policy-ready framework for managing infectious outbreaks in urban food systems.
This research aligns with global food safety goals and supports the UN Sustainable Development Goals (SDG 3, 11, and 12).
For Ghana and beyond, this research underscores the urgent need for better regulation, monitoring, and public health oversight of digital food platforms, particularly in rapidly urbanizing and densely populated cities.
As the online food delivery industry continues to grow, especially in emerging economies such as Ghana, Nigeria, Kenya, and India, the lack of standardized food safety protocols and oversight for delivery chains has emerged as a major public health risk.
Emmanuel Addai’s research provides an evidence-based mathematical framework for policymakers to anticipate and manage these risks through optimal interventions.
This work is particularly impactful for developing nations, where informal food vendors and under-regulated delivery systems often operate outside the scope of national health standards.
His model can be adapted to simulate various real-world conditions urban slums, peri-urban hubs, and even cross-border trade routes, allowing government agencies and health departments to simulate outbreak scenarios, prioritize inspection strategies, and develop early-warning systems.
Furthermore, Addai’s contribution supports Ghana’s national priorities under the Ghana Food Safety Policy and aligns with UN Sustainable Development Goals (SDGs), especially:
• SDG 3: Good health and well-being,
• SDG 11: Sustainable cities and communities,
• SDG 12: Responsible consumption and production.
Ultimately, Emmanuel Addai’s contribution stands as a critical bridge between theoretical science and practical policy application, enabling stakeholders to make data-driven decisions in regulating the fast-growing online food delivery ecosystem.
This makes his research not only nationally important to Ghana’s public health strategy but also internationally recognized as a novel methodology applicable in both low- and high-income settings.

Muslims across the country celebrated this year’s Eid-ul-Adha in a colourful and spiritually uplifting atmosphere under the theme, “A Season of Sacrifice, Solidarity and Spiritual Renewal.”
The celebration brought together Muslims from diverse backgrounds in a remarkable display of faith, unity and cultural heritage.
The occasion was marked by special Eid prayers at various designated grounds, the slaughtering of rams in homes for sharing among family members, friends and the less privileged, as well as musical concerts and recreational activities including horse riding.
Leading the celebration was the Chief Imam, Dr Sheikh Osman Sharubutu.
While the national celebration was held at the Black Star Square where President John Dramani Mahama was the Special Guest of Honour, similar gatherings took place at different centres across the capital and other regions of the country.
A visit by The Spectator to some celebration grounds revealed Muslims, both young and old, elegantly dressed in colourful jalabiya and other Islamic attire, reflecting the rich culture and traditions of the Muslim community.
The celebration also portrayed the spirit of religious tolerance and peaceful coexistence in the country, as a number of Christians joined their Muslim counterparts to mark the occasion.
Muslim leaders and government officials used the opportunity to call on the faithful to uphold the teachings of the Holy Quran, renew their spiritual commitment and refrain from acts capable of undermining the peace, unity and security of the nation.
They further urged Ghanaians to continue to live in harmony and support one another for national development.

Dear Obaa Yaa,
During Eid-ul- Adha celebration, I decided to spend the weekend at my boyfriend’s place since we were planning towards our marriage.
To my surprise, what keeps me wide awake, restless and frustrated every single time is that he snores loudly like a generator running on full power, and I genuinely cannot get any rest
At a point, I thought it was just a normal thing, but I have realised it is something he does with ease and doesn’t see anything wrong with it.
When he steps out in the morning, I try to get enough sleep because I may not sleep in the evening.
The most annoying thing is that, he always wants to cuddle me. These two things are a no for me and a red flag.
We are about to get married, what should I do?
Enam, Keta.
Dear Enam,
The snoring and constant cuddling are frustrating, but you don’t have to choose between sleep and closeness.
Start with the snoring: check if it’s worse when he sleeps on his back, cut out alcohol before bed, try nasal strips or a humidifier, and see a doctor if he pauses while breathing.
For quick relief, foam earplugs or noise-cancelling headphones help a lot.
Separate blankets, a bigger bed, or sleeping apart on some nights often makes couples rest well and feel closer overall.
Bring this up before the wedding .Tell him you want to wake up next to him for years to come, but sleep deprivation makes you both miserable.
Test earplugs and side-sleeping this weekend, and if it’s still unbearable, bring in a doctor. Good sleep matters more for your marriage than staying glued together all night.
