About this study
Official title: Health Impacts of Fresh Cut Street Vended Fruits: A Controlled Intervention Study
This study will employ a randomized controlled intervention design to evaluate the health impacts of consuming fresh-cut street-vended fruits, focusing on microbial contamination and gastrointestinal (GI) symptoms. A total of 300 participants will be recruited and divided into treatment (consuming guava, pineapple, or watermelon) and control groups (no fruit consumption). Fruit samples will be analyzed for microbial contamination, including S. aureus and E. coli, using standard microbiological and molecular techniques. Data on GI symptoms will be collected through questionnaires and analyzed using statistical methods, such as Chi-square tests, Kaplan-Meier survival analysis, and Cox proportional hazards regression. Spearman correlation will identify associations between bacterial presence and specific symptoms. Ethical approval will be obtained, and participant safety will be prioritized. Analytical tools, including IBM SPSS, RStudio, and PyCharm, will be utilized for the analyses.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fresh-Cut Guava ConsumptionDietary supplement
Participants eat a defined portion of guava.
Fresh-Cut Pineapple ConsumptionDietary supplement
Participants consumed fresh-cut pineapple purchased from street vendors. Health outcomes, including potential microbial contamination and GI symptoms, were assessed for five days after consumption.
Fresh-Cut Watermelon ConsumptionDietary supplement
Fresh-Cut Watermelon Consumption Description: Participants consumed fresh-cut watermelon obtained from street vendors. GI symptoms and microbial contamination effects were monitored for five days following consumption.
Fresh-Cut Guava Consumption (With Gastric Acidity)Dietary supplement
Same as intervention 2, but in participants with acidity
Fresh-Cut Pineapple Consumption (With Gastric Acidity)Dietary supplement
Same as intervention 3, but in participants with acidity.
Fresh-Cut Watermelon Consumption (With Gastric Acidity)Dietary supplement
Same as intervention 4, but in participants with acidity.
| Study group | Role | What they receive |
|---|---|---|
| Control Group (No Fresh-Cut Fruit Consumption) | No intervention | Participants in this group did not consume any street-vended fresh-cut fruits. They continued their usual dietary habits, avoiding any foods that could potentially cause irritation or foodborne illness. This group served as a baseline for comparison against the treatment groups. |
| Fresh-Cut Fruit Consumers with Gastric Acidity (Guava) | Experimental | Participants with pre-existing gastric acidity conditions consumed fresh-cut guava from street vendors. Their health status was monitored for five days post-consumption, focusing on gastrointestinal (GI) symptoms and microbial contamination effects. Receives: Dietary Supplement: Fresh-Cut Guava Consumption (With Gastric Acidity) |
| Fresh-Cut Fruit Consumers with Gastric Acidity (Pineapple) | Experimental | Participants with pre-existing gastric acidity conditions consumed fresh-cut pineapple from street vendors. Post-consumption symptoms and microbial contamination were assessed over a five-day period. Receives: Dietary Supplement: Fresh-Cut Pineapple Consumption (With Gastric Acidity) |
| Fresh-Cut Fruit Consumers with Gastric Acidity (Watermelon) | Experimental | Participants with pre-existing gastric acidity conditions consumed fresh-cut watermelon from street vendors. GI symptoms and potential microbial contamination effects were monitored for five days. Receives: Dietary Supplement: Fresh-Cut Watermelon Consumption (With Gastric Acidity) |
| Fresh-Cut Fruit Consumers without Gastric Acidity (Guava) | Experimental | Participants without pre-existing gastric acidity conditions consumed fresh-cut guava from street vendors. Health status was tracked for five days, with a focus on microbial contamination and foodborne illness symptoms. Receives: Dietary Supplement: Fresh-Cut Guava Consumption |
| Fresh-Cut Fruit Consumers without Gastric Acidity (Pineapple) | Experimental | Participants without pre-existing gastric acidity conditions consumed fresh-cut pineapple from street vendors. The study monitored their health for five days to evaluate any adverse effects. Receives: Dietary Supplement: Fresh-Cut Pineapple Consumption |
| Fresh-Cut Fruit Consumers without Gastric Acidity (Watermelon) | Experimental | Participants without pre-existing gastric acidity conditions consumed fresh-cut watermelon from street vendors. GI symptoms and microbial contamination effects were assessed over five days. Receives: Dietary Supplement: Fresh-Cut Watermelon Consumption |

- Model description
- This study employs a randomized controlled intervention design with a parallel assignment model to evaluate the health impacts of consuming fresh-cut street-vended fruits, focusing on microbial contamination and gastrointestinal (GI) symptoms. A total of 300 participants will be assigned to one of seven arms: two treatment arms with 75 participants each (one with gastric acidity problems and one without), subdivided into three subgroups based on the type of fruit consumed (guava, pineapple, and watermelon). Additionally, a control group of 75 participants will not consume any fresh-cut street-vended fruits and will follow their usual dietary habits. The primary aim is to assess the microbial load (Total Viable Count, S. aureus, and E. coli) on fruits and its association with the development of GI symptoms. The study will employ statistical analysis techniques, including chi-square tests, relative risk analysis, and correlation studies, to evaluate the impact of fruit consumption on

Questions about this trial
What is this clinical trial studying?
A study testing Fresh-Cut Guava Consumption, Fresh-Cut Pineapple Consumption and Fresh-Cut Watermelon Consumption in people with Gastrointestinal Diseases and Foodborne Diseases, run by Bangladesh Agricultural University at 1 site in Bangladesh.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 20 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Bangladesh. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
