The reference to mechanical capping in Section 34591 of the Food and Agricultural Code, is construed to mean that bottle caps must be applied to bottles by mechanical means as well as said bottles being capped by mechanical means. Application of caps to milk bottles by hand is not considered to be by mechanical means and is therefore prohibited.
