Survival of Campylobacter fetus subsp. jejuni in Cheddar and Cottage Cheese

Abstract
Campylobacter fetus subsp. jejuni inoculated into Cheddar cheese milk at concentrations ranging from 102–106 cells per ml was not detectable in the curd after 30–60 d of curing. When milk for cottage cheese manufacture was inoculated with 105–106 cells of C. fetus subsp. jejuni, the organism was not detectable in the whey or curd after cooking for 30 min at 55°C.
