Uptake of Encapsulated Ferrous Fumarate Double Fortified Salt in the Public Distribution System in India: A Value Chain Analysis

Introducing double fortified salt in social safety net programmes in Madhya Pradesh and Gujarat in India: Success factors, challenges and lessons learned

Double fortified salt (DFS; with iron and iodine) was introduced in social safety net programmes (SSNPs) in Madhya Pradesh (MP) and Gujarat states in 2018. Nutrition International (NI) provided critical support for the intervention. An impact evaluation in MP found high DFS uptake, exceeding 90%. Conduct a process evaluation of the DFS programmes in MP and Gujarat states to identify success factors, challenges, and recommend considerations for scale-up. Twenty-eight qualitative interviews were conducted with NI staff, national and state level government officials, and DFS producers in 2022. Enabling environmental factors included national-level support for food fortification, consensus that anaemia was essential to address, and institutional trust in NI for technical assistance. In programme implementation, the primary challenges were reports of black specks in DFS and the darkening of food cooked with DFS. NI supported the government in improving handling practices, ensuring a regular and stable supply, introducing quality monitoring efforts and launching targeted behaviour change communication (BCC) campaigns regarding the value of DFS. Long-term implementation of the programmes is a weak point, as DFS production is more expensive than iodised salt, there is no existing market outside of institutional demand, and BCC must be long-term, high-quality, and requires resourcing for continued high uptake among SSNP beneficiaries. Strong government buy-in and technical support along the supply chain to address quality issues and beneficiary acceptance were key factors for the successful introduction of DFS. Comparative studies of DFS programmes should be conducted to improve confidence in the success factors that lead to high DFS uptake.

Field-friendly MUNNG® optima simple test kit for quick qualitative assessment of iodine and iron presence in double-fortified salt

Background

Data from several efficacy studies and a long-term effectiveness study have encouraged the governments to adopt a policy of providing double-fortified salt (DFS) in the Mid-Day Meal (MDM) programs in government schools across India. These envisaged food security events are likely to boost the manufacturing of DFS in a big way. Thus, it becomes pertinent to come up with a robust monitoring system involving community and field workers for quality checks. It is imperative to equip these field workers with simple testing kits (STKs) capable of qualitative detection of iron and iodine in DFS. As the consumer acceptance of foods is based on several factors including sensory characteristics, performance, convenience, cost, nutrition, and product image, a variety of iron compounds are in use for fortification. However, it becomes challenging to provide a kit that can overcome the chemical masking of iodine detection by iron compounds.

Objectives

We aimed at (1) the development of a field-friendly STK for quick qualitative assessment of iodine and various forms of iron present in DFS, (2) to check its validity under field conditions.

Methods

We put in place reagents combined using known chemical reactions and balanced use of oxidants to overcome the problems of encapsulation and to maximize the use, by enabling reagent combination to react with all forms of iron.

Results

The kit reagents successfully detect iodine as well as three commonly used iron fortificants in DFS. Published field trials confirmed the specificity and sensitivity of the developed kit. The simplicity and use of the kit by a field worker can be seen in the enclosed video.

Conclusion

The combination of improvised kit reagents allows early detection of iron and iodine in DFS. Iron is detected in a variety of iron-containing fortifications. The provision of diluted H2O2 ensures the presence of oxygen-free radicals that enhances iodine release captured by concentrated KI making iodine detection an easy task.

Iron Fortification through Universal Distribution of Double-Fortified Salt Can Increase Wages and Be Cost-Effective: An Ex-Ante Modeling Study in India

BACKGROUND

The alleviation of iron deficiency through iron supplementation has not effectively reduced anemia in India, mainly due to low compliance. Food fortification with iron is considered a viable alternative, and the provision of double-fortified salt (DFS; with iron and iodine) has been mandated in public health programs. Limited evidence exists on its benefit-cost ratio.

OBJECTIVE

In this study we sought to estimate the economic benefit in terms of increased wages in relation to introduction of DFS in reduction of anemia and the cost of doing so.

METHODS

The economic benefit of introducing DFS in India was derived using a series of mathematical, statistical, and econometric models using data from national surveys capturing earnings and dietary iron intake of the population. Anemia status was predicted from data on dietary intake, sanitation, and for women, menstrual losses. The impact of iron deficiency anemia (IDA) on wages was estimated using a Heckman Selection model and 2-stage least squares procedure. Benefit of DFS was estimated through increased wages attributed to anemia reduction compared with its cost.

RESULTS

Men and women with IDA had lower wages (by 25.9%, 95% CI: 11.3, 38.1; and by 3.9%, 95% CI: 0.0, 7.7, respectively) than those without IDA. Additional iron intake through DFS was predicted to reduce prevalence of IDA (from 10.6% to 0.7% in men and 23.8% to 20.9% in women). The economic benefit-cost ratio of introducing DFS at a national level was estimated to be 4.2:1.

CONCLUSIONS

Iron fortification delivered through DFS under a universal program can improve wages and be sufficiently cost-effective for its implementation at scale in India.
