No, pool salt is emphatically not food safe and should never be ingested.
While both pool salt and common table salt share the chemical compound sodium chloride (NaCl), their purity levels and intended uses are drastically different. The primary reason pool salt is unsuitable for consumption is the potential presence of impurities and additives that are harmless in a pool environment but can be harmful if ingested.
As highlighted by experts, you must "keep well away from pool salt, as you may end up ingesting potentially toxic chemicals." These chemicals are often used to prevent caking, aid solubility, or simply are by-products of less rigorous refining processes compared to food-grade salt.
Key Differences: Pool Salt vs. Table Salt
To put things into perspective, consider the distinct purposes of each type of salt. Regular table salt (food-grade salt) undergoes a stringent purification process to remove minerals and potential contaminants, ensuring it is safe for human consumption. Pool salt, on the other hand, is manufactured for water treatment in swimming pools and does not undergo the same rigorous purification or quality control checks for ingestion.
The reference clarifies this distinction: "you can use both pool salt and regular table salt in a saltwater pool, but you can only use table salt for seasoning your food." This clearly underscores that pool salt is not intended for culinary use.
| Feature | Pool Salt | Table Salt (Food Grade) |
|---|---|---|
| Purity | Lower purity, may contain impurities/additives | High purity, specifically refined for consumption |
| Additives | May include anti-caking agents, anti-algae etc. not safe for ingestion | May include iodine or anti-caking agents safe for ingestion |
| Intended Use | Maintaining pool chemistry and sanitization | Culinary use, food preservation, dietary supplement |
| Safety | Not food safe, potentially toxic if ingested | Food safe for human consumption |
| Regulations | Governed by pool chemical safety standards | Governed by food safety and health regulations |
Potential Risks of Ingesting Pool Salt
Ingesting pool salt can lead to a range of adverse health effects due to the presence of non-food-grade impurities or additives. These risks can include:
- Gastrointestinal Distress: Nausea, vomiting, and diarrhea.
- Toxic Chemical Exposure: Depending on the specific impurities, ingestion could lead to more severe poisoning.
- Organ Damage: Long-term or significant exposure could potentially harm kidneys, liver, or other organs.
- Dehydration and Electrolyte Imbalance: Like any high-sodium intake, it can lead to these issues, exacerbated by impurities.

Safe Handling and Storage
To prevent accidental ingestion, especially in households with children or pets, it is crucial to handle and store pool salt properly:
- Clearly Label: Ensure all containers of pool salt are clearly labeled and distinct from food items.
- Separate Storage: Store pool salt in a separate, secure location away from the kitchen or food storage areas.
- Original Packaging: Keep pool salt in its original packaging to ensure all warning labels and instructions are visible.
- Education: Inform all household members about the dangers of ingesting pool salt.
Always prioritize safety and use products only for their intended purposes. For culinary needs, always opt for food-grade salt from reputable sources.
