Childhood dietary exposure of aflatoxins and fumonisins in Tanzania: A review
Mollay, Clara; Kassim, Neema; Stoltzfus, Rebecca; Kimanya, Martin (Taylor & Francis Online, 2020-12-24)Aflatoxins (AFs) and Fumonisins (FBs) are common contaminants of maize, from secondary metabolites of fungi. Presence of AFs and FBs in maize-based complimentary food is evident in various studies conducted in Tanzania and ... -
Complementary feeding in Kongwa, Tanzania: Findings to inform a mycotoxin mitigation trial.
Mollay, Clara; Kassim, Neema; Stoltzfus, Rebecca; Kimanya, Martin (John Wiley & Sons Ltd., 2021-05-04)Complementary feeding of 6- to 24-month-old infants and young children with adequate, safe and developmentally appropriate food is essential to child health. Inappropriate complementary foods and feeding practices are ... -
Ethical considerations in the design and conduct of a cluster-randomised mycotoxin mitigation trial in Tanzania
Phillips, Erica; Turner, Paul; Ngure, Francis; Kassim, Neema; Makule, Edna; Smith, Laura; Nelson, Rebecca; Stoltzfus, Rebecca (Wageningen Academic Publishers, 2022-01-24)Aflatoxins are fungal metabolites that commonly contaminate staple food crops in tropical regions. Acute aflatoxin consumption in very high concentration causes aflatoxicosis and acute liver failure, while chronic, moderate ... -
Ethical Considerations of the Trial to Establish a Causal Linkage Between Mycotoxin Exposure and Child Stunting
Phillips, Erica; Turner, Paul; Kassim, Neema; Makule, Edna; Nelson, Rebecca; Ngure, Francis; Smith, Laura; Stoltzfus, Rebecca (Elsevier, 2021-06-21)Objectives Aflatoxins are fungal metabolites that commonly contaminate staple crops in tropical regions. Aflatoxin is a carcinogen and consumption at high-levels can lead to acute liver failure and aflatoxicosis. Multiple ... -
Main complementary food ingredients contributing to aflatoxin exposure to infants and young children in Kongwa, Tanzania
Mollay, Clara; Kimanya, Martin; Kassim, Neema; Stoltzfus, Rebecca (Elsevier Ltd., 2021-11-23)Complementary foods (CFs) provided to infants and young children (IYC) in sub-Saharan Africa contain ingredients that are susceptible to aflatoxin contamination. Chronic dietary exposure to aflatoxins is associated with ... -
Nutrient intake and dietary adequacy among infants in Kongwa District, Tanzania: A sub-study of the Mycotoxin Mitigation Trial
Kayanda, Rosemary; Phillips, Erica; Kassim, Neema; Ngure, Francis; Stoltzfus, Rebecca (Research Square, 2023-04-13)Background: Early exposure to aflatoxin, a common toxin in global food systems, has been associated with child growth faltering. The Mycotoxin Mitigation Trial was a community-based cluster-randomized trial designed to ... -
Processing complementary foods to reduce mycotoxins in a medium scale Tanzanian mill: A hazard analysis critical control point (HACCP) approach
Ngure, Francis; Makule, Edna; Mgongo, William; Phillips, Erica; Kassim, Neema; Stoltzfus, Rebecca; Nelson, Rebecca (Elsevier, 2024-03-22)Designing and implementing processing procedures for producing safe complementary foods in dynamic and unregulated food systems where common food staples are frequently contaminated with mycotoxins is chal- lenging. This ... -
Protocol for the trial to establish a causal linkage between mycotoxin exposure and child stunting: a cluster randomized trial.
Phillips, Erica; Ngure, Francis; Smith, Laura; Makule, Edna; Turner, Paul; Nelson, Rebeca; Kimanya, Martin; Stoltzfus, Rebecca; Kassim, Neema (BMC Public Health, 2020-05-01)Background: The number of stunted children has fallen globally but continues to increase in Africa. Stunting is estimated to contribute to 14–17% of child deaths under 5 years of age and is a risk factor for poor cognitive ... -
