E710 – Spiramycins

Description

Mixture of macrolide antibiotics produced by Streptomyces ambofaciens

Risks

Notes

E710 is spiramycin, which consists of a mixture of related antibiotic compounds produced by bacteria called Streptomyces ambofaciens. These bacteria are found naturally in soil and create spiramycin as part of their chemical warfare against competing microorganisms. The antibiotic is produced by growing these bacteria in large fermentation vessels under carefully controlled conditions, then extracting and purifying the spiramycin compounds they produce. Spiramycin works by interfering with bacteria's ability to make essential proteins, effectively stopping their growth and killing them. While this action could theoretically make it useful as a food preservative to prevent spoilage and foodborne illness, spiramycin is primarily used in human and veterinary medicine rather than food production. It's particularly valued in medical settings for treating certain infections, especially in patients who can't take other types of antibiotics. E710 is not approved for use as a food additive in most countries due to the same antibiotic resistance concerns that apply to other antibiotic-based preservatives. Using antibiotics in food could contribute to bacteria developing resistance, potentially making these important medicines less effective for treating serious infections. Additionally, people with allergies to macrolide antibiotics could face unexpected reactions. This additive is not considered suitable for food use regardless of dietary preferences due to these significant health and safety considerations.
