Hi,

I've been lurking here to learn the ins and outs of milk allergies.

I'm looking for information on what it takes to manufacture food/food
supplements that are safe for people who are severely allergic--especially
what kinds of certifications for raw ingredients are necessary and what
kinds of handling and cleaning procedures are adequate.  Unfortunately, I
have not been able to find this information in the technical literature.

Can you direct me to sources?

Barbara
