E. coli and Campylobacter can persist on dairy farms for months and contaminate unpasteurized, bulk tank milk despite some hygiene measures, according to a thesis.
Anniina Jaakkonen’s work investigated the frequency and contributing factors of milk contamination by Shiga toxin-producing E. coli (STEC) and Campylobacter jejuni on Finnish dairy farms. It is based on three publications: one in 2017 in the journal Zoonoses and Public Health, another in 2019 in Applied Environmental Microbiology and the final one in April this year in the journal PLoS ONE
