Preventing botulism with pickling salt
Salt has been used as a preserving agent since ancient times. While today we often rely on freezers for storing food, salt still plays a crucial role in extending the shelf life of many foods. For example, adding pickling salt to meats helps them last longer while also reducing the risk of foodborne illness.

What is Botulism?
Botulism is a severe neurological disease caused by the botulinum toxin. This toxin attacks the nervous system and can lead to serious symptoms, including:
- Blurred vision
- Dizziness
- Difficulty swallowing
- Dry mouth
- Muscle paralysis
Foodborne botulism often arises from poorly processed foods such as vacuum-packed items, tinned products, sauces, or traditionally smoked meats. The danger is that contaminated foods may look and smell perfectly normal, making it hard to detect before consumption.
What is Pickling Salt?
Pickling salt is a special type of salt that contains sodium nitrite (NaNO₂), also known as E250. This salt is carefully dosed during production to ensure it preserves food safely.
How Pickling Salt Prevents Botulism
The addition of pickling salt to smoked or prepared meats prevents the growth of the harmful botulinum bacteria. Beyond safety, pickling salt also helps the meat:
- Maintain its color and prevent greying
- Retain its flavor
- Stay less sensitive to temperature changes, which extends shelf life
Because of its color-preserving properties, pickling salt is sometimes referred to as color salt or colorozo.
Safe Food Preparation Guidelines
To minimize the risk of botulism and safely preserve meat:
- Prepare food in a clean and hygienic environment
- Heat foods to a temperature above 85 °C
- Use a reliable pickling salt, such as JAMONSAL
Using pickling salt ensures that your meats are not only delicious but also safe to consume.
