Natamycin E235, also known as pimaricin and sometimes sold as Natacyn, is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil.

Though it’s considered safe, some are convinced it has potentially dangerous health effects.

One Response to “Natamycin Side Effects”

Thank you so much for this article. Pimaricin/ Natamycin/E235 causes severe respiratory distress in my body. I have been 9n an asthma pump 4 times per night for the past six months before finding the culprit.
As a rule E…any number is fatal to sensitive people which eliminates practically all sweets, cool drinks, fruit juices ready made salads, tinned food l, wine and other beverages from the diet. Lung distress sends us rushing to the medical profession who pump further chemicals into the situation. No wonder the cancer rate is astronomical. Please, if your kids suffer with respiratory distress at night , look at preservatives colourants, pesticides, herbacides in the food the consume. Even lightly salted crisps are a killer for sensitive children because of the E-content factor.
I am so grateful for your article. I hope to be off asthma pumps for good soon.
Thank you very much indeed
