Anyone know how I can find out if Michigan has any health/safety laws for selling eggs? There's quite a few small flock owners near me with signs out, selling fresh eggs. Are there rules about not reusing egg cartons? Mandatory vaccinations? Inspections? Safe handling after laying? How do I find out? The local feed mill buys and sells eggs for small flock owners, in reused cartons, so I'm wondering how restrictive the rules can be. Even with the salmonella outbreak from the huge egg companies, the feed mills are still selling like they used to.
