Sodium Dichloroisocyanurate (SDIC) Fumigation for Poultry Health
SDIC (Sodium Dichloroisocyanurate, also known as NaDCC, DCCNa, or Dichlor), is a highly effective, low-toxicity and cost-effective chlorine-based disinfectant recognized by the WHO. It belongs to the family of chlorine-based disinfectants along with bleaching powder, chlorine dioxide, and sodium hypochlorite. It can replace traditional chlorine-based disinfectants such as bleaching powder and 84 disinfectant. Due to its strong oxidizing property, DCCNa has a wide range of applications and has covered various fields such as household daily disinfection, hygiene guarantee in the food processing industry, swimming pool water purification, and drinking water disinfection and sterilization.
In the context of modern large-scale poultry farming, disinfection of poultry houses is a key measure for preventing diseases, reducing mortality rates, and improving production efficiency. Fumigation disinfection is the most commonly used and effective method. The traditional method involves using formalin and potassium permanganate to produce formaldehyde gas, but formaldehyde is carcinogenic. Currently, SDIC has been used as a safer fumigation disinfectant. This highly stable and efficient disinfectant provides a comprehensive disinfection solution for poultry farms and hatcheries, successfully replacing the traditional and dangerous formaldehyde-based disinfection schemes.
1. Technical Advantages of SDIC in Modern Fumigation
As global biosecurity standards evolve, SDIC has demonstrated unique value in both air purification and disinfection. Unlike liquid sprays, the smoke-based delivery of
sodium dichloroisocyanurate disinfectant offers superior penetration, reaching ventilation ducts and equipment crevices that are often missed by traditional cleaning.

2. The application method of SDIC for fumigation
| Application Target | Recommended Formula | Recommended Dosage |
|---|---|---|
| Poultry House Fumigation | SDIC (45% Cl) 1000g + Glucose 320g + Auxiliary Agent | 5-10g / m³ |
| Hatching Egg Sterilization | SDIC (45% Cl) 1000g + Glucose 320g + Auxiliary Agent | 5g / m³ |
3. Sterilization Performance of SDIC Chemical
Field data confirms the superior performance of dichlor sanitizer. In controlled tests conducted at 12°C, a standard dosage of 10g/m³ achieved a 100% bacterial kill rate on floors, walls, and cage surfaces within a 12-hour window. Furthermore, safety assessments in hatcheries show that SDIC fumigation achieves high surface sterilization rates (exceeding 90%) without adversely affecting egg hatchability or chick vitality.

4. Precautions during fumigation disinfection
Smoke disinfection only works on the surface of objects and cannot penetrate thick dirt, feces or feed residues. Therefore, thorough mechanical cleaning and preliminary spray disinfection must be carried out before fumigation to remove organic waste and improve the overall disinfection efficiency.
The disinfection effect relies heavily on smoke concentration and available chlorine content. A tightly sealed poultry house can maintain stable smoke concentration and maximize the disinfection performance. Before fumigation, check the entire house carefully. Any gaps, cracks or openings should be sealed with plastic sheets or adhesive tape to avoid smoke leakage, which will significantly reduce the disinfection result.
Select containers that are large enough and highly resistant to corrosion. Place the containers on a smooth cement floor, and keep them away from any flammable materials to ensure safe operation. NaDCC fumigant burns, generating smoke. The burning area generally lasts for 10 to 30 minutes.
First, pour NaDCC fumigant into a corrosion-resistant container. Ignite NaDCC fumigant to generate smoke safely without open flames, ensuring stable and complete reaction.
For poultry house disinfection, keep the house closed for at least 24 hours before ventilation. If conditions allow, sealing the house for 1 to 2 weeks can achieve a more thorough disinfection effect. For hatching eggs, maintain a closed environment for 30 to 60 minutes, then start ventilation in a proper way.
The fumigation smoke is strongly irritating. Wear proper protection during fumigation to prevent risks. Prepare the disinfectant solution just before use, and keep it away from heat sources.
