The Campylobacter prevalence for Danish chilled meat sampled at
retail remained fairly unchanged within the study period, 2001–2010,
with a slight decrease from2005 to 2008. This is not in complete agreementwith
results fromanother Danish surveillance programme,where
the proportion of Campylobacter positive samples of chilled meat at the
large Danish slaughterhouses decreased within the period 2004–2006
(Rosenquist et al., 2009; Anonymous, 2012). According to the sampling
scheme, retail samples should represent the products available for sale.
This sampling might lead to an overrepresentation of meat from the
smaller producers when compared to the actual sale. The sale of meat
from smaller producers accounts for approximately 2% of the total
sale, while products from the smaller producers may account for more
than 2% in the display counter. Meat from the smaller producers often
consists of special productions, i.e. meat from older birds with a higher
probability of being positive for Campylobacter, organic production, etc.
Furthermore, the smaller slaughterhouses do not have the possibility of
implementing for example scheduling. Being aware of the prevalence
being higher from these productions (data not shown) the modelled
risk from Danish meat might be somewhat higher than the actual
risk. However, the way of sampling was consistent over years, so a
bias would be consistent.
