I looked it up the other day when they first said about adding this the definition is:
Flavophospholipol: Antibiotic complex obtained from Streptomyces bambergiensis containing mainly Moenomycins A and C. They are used as feed additives and growth promoters for poultry, swine, and cattle.
So if you want you meat antibiotic free and are currently feeding liquid feeds check out each and everything in them. No where do they say this is antibiotic and yet everywhere I looked that's exactly what it is, and it's used to fight Ecoli in feedlots!
I'm so irritated that it never ends with the tampering with food and glossing over... and they say we have too many antibiotics from doctors... too much in food still!!
