Introduction: Why Restrict Certain Ingredients in Food?

Background:

Ensuring public access to safe and wholesome food is a foundational responsibility of every modern nation. The Food Safety and Standards Authority of India (FSSAI), under the Food Safety and Standards Act, 2006, is the central regulatory authority tasked with safeguarding consumer health and promoting fair practices in the food trade. As part of its broad mandate, FSSAI enforces specific regulations prohibiting or restricting the use of certain food ingredients that are scientifically known to be harmful, even if historically accepted in diets.

One such regulation is Clause 2.2 of the Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011, which places stringent restrictions on the use of Kesari Dal (Lathyrus sativus) and its derivatives. Though traditionally consumed in some parts of India, Kesari Dal has been linked with serious neurological disorders and is therefore restricted for public health reasons.

This article delves into the scientific rationale, regulatory framework, linguistic considerations, and practical implications of Clause 2.2, which addresses the prohibition on the sale and use of Lathyrus sativus in food production and trade.

Clause 2.2 – Overview and Scope

Clause 2.2 specifically restricts the sale, offering for sale, exposure for sale, or possession for sale of Lathyrus sativus (commonly known as Kesari Dal or Kesari Gram), as well as its derivatives, mixtures, and products. This applies to all Indian states from the date specified by the respective state governments via notification in their official gazette.

The following food items and combinations are expressly restricted:

  1. Kesari Gram (Lathyrus sativus) and its products
  2. Kesari Dal (Lathyrus sativus) and its products
  3. Kesari Dal Flour and its products
  4. Mixtures of Kesari Gram with Bengal Gram (Cicer arietinum) or any other gram
  5. Mixtures of Kesari Dal with Bengal Gram Dal or any other dal
  6. Mixtures of Kesari Dal flour with Bengal Gram flour or any other flour

These restrictions are absolute unless a state government specifies otherwise through official notification. Even in cases of incidental contamination or accidental presence, Clause 2.2 allows a maximum permissible limit of 2% of Lathyrus sativus in gram or pulse mixtures.

Scientific and Health Rationale for the Ban

The basis for Clause 2.2 lies in robust medical and toxicological studies that have shown a strong link between consumption of Lathyrus sativus and neurolathyrism, a degenerative disorder of the nervous system. This condition is characterized by:

  • Muscle weakness and spastic paralysis, particularly in the lower limbs
  • Irreversible motor neuron damage
  • Walking difficulties or permanent disability

The neurotoxin responsible is β-N-Oxalyl-L-α,β-diaminopropionic acid (ODAP), which is naturally present in Lathyrus seeds. While the crop is drought-resistant and cheap to cultivate—often consumed by economically weaker populations during famine or scarcity—it is toxic in large quantities or when consumed regularly.

As a result, public health bodies, including the Indian Council of Medical Research (ICMR) and the World Health Organization (WHO), have issued cautions regarding its unrestricted use. FSSAI’s Clause 2.2 thus functions as a preventive regulation rooted in well-established scientific evidence.

Cultural and Historical Context of Kesari Dal

Kesari Dal has a long history of consumption in rural India, particularly in regions like Uttar Pradesh, Bihar, Madhya Pradesh, Chhattisgarh, Odisha, and parts of Maharashtra and Andhra Pradesh. It was often used as a cheap substitute for more expensive pulses like arhar, moong, or masoor.

Its popularity stemmed from:

  • Affordability during food scarcity
  • High protein content
  • Resistance to drought and pests, making it easy to cultivate

However, this historical utility does not override the health risks it poses. The regulation carefully considers this context by allowing up to 2% of incidental contamination, recognizing that minor traces may unintentionally occur during harvesting or transportation.

Linguistic and Regional Identifiers

Clause 2.2 goes a step further by providing an exhaustive list of names for Kesari Dal in multiple Indian languages, which is critical for enforcement across India’s diverse linguistic landscape. Here are a few key examples:

  • Hindi: Khesari, Kessur, Kassartiuri, Batura, Kansari
  • Marathi: Lakheri, Batri, Mutra, Botroliki-dal
  • Gujarati: Lang
  • Punjabi: Kisari, Chapa, Karas
  • Tamil: Muku
  • Kannada: Laki Bele
  • Bengali: Kassur, Teora, Batura
  • Oriya: Khesra
  • Assamese: Teora
  • Sanskrit: Sandika, Triputi
  • English: Chickling Vetch

By identifying regional aliases, the regulation ensures clarity in compliance, especially for small traders, farmers, and enforcement officers.

Regulatory Framework and State-Level Implementation

While Clause 2.2 is a national directive under the FSSAI, enforcement is tied to state-level notifications. Each state must publish its own effective date of implementation in the official gazette. This decentralization allows flexibility for states to phase in the restriction based on local consumption patterns, availability of alternatives, and awareness levels.

States may also conduct public awareness drives or issue additional guidelines for local FBOs (Food Business Operators), especially during harvest or market season for pulses.

Impact on Food Business Operators (FBOs)

Food Business Operators—especially those involved in pulse milling, flour production, retail packaging, and exports—must ensure:

  1. Stringent Supplier Screening: All procurement of dal, gram, or flour must be from verified sources that guarantee Lathyrus-free batches.
  2. In-House Testing and Quality Control: Periodic testing must confirm that accidental presence of Kesari Dal is within the 2% permissible limit.
  3. Documentation: Accurate batch-wise records, supplier declarations, and lab reports must be maintained to establish due diligence.
  4. Training and Awareness: Staff involved in sorting, packing, and quality checks must be trained to identify Kesari Dal by sight and labeling.

Failure to comply with Clause 2.2 can lead to:

  • Seizure of contaminated stocks
  • Product recalls
  • Fines and penalties under the FSS Act
  • Suspension or cancellation of licenses

Consumer Implications

For consumers, especially in rural areas, the restriction has multiple benefits:

  • Reduction in long-term neurological risks, especially among the poor who may unknowingly consume the cheaper dal.
  • Improved awareness about food safety and toxic ingredients.
  • Promotion of safer alternatives, such as arhar, moong, or chana dal.

 

FSSAI and state governments periodically release advisories and conduct awareness drives, particularly in states with high historical use of Kesari Dal.

Allowable Limit and Justification

Even though the regulation bans direct sale or use of Kesari Dal, it allows a tolerance limit of 2% for unintentional contamination in pulses or flour. This limit is:

  • Based on scientific risk assessment of the amount of ODAP toxin that would pose harm in small, occasional quantities.
  • Aligned with international practices that permit minor accidental inclusion of restricted ingredients where zero contamination is practically difficult to enforce.

This thoughtful flexibility ensures that food businesses are not penalized for trace-level, non-intentional mixing during harvest or transit.

Conclusion: A Model Clause in Risk-Based Food Regulation

Clause 2.2 of the Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011 demonstrates how regulatory frameworks can be scientifically robust, contextually aware, and enforceable across a diverse population. By targeting Lathyrus sativus (Kesari Dal)—a known neurotoxic agent—it removes a major food safety threat while offering operational leeway through permissible thresholds.

This clause not only reflects India’s evolving food safety laws but also balances public health with ground realities. As India progresses toward a safer and more reliable food system, regulations like Clause 2.2 play a foundational role in shaping national food safety policy and protecting the health of millions.
