Please send your child with a brown bag lunch. All food needs to be certified as Kosher. You can easily find many products in Publix or Kroger that bear a Kosher certification as sampled below. The food can be either dairy, meat, or Pareve (non dairy or meat).
We suggest you Do Not send a lunch box as these tend to get lost or left at camp. A brown bag is a much better idea.
