Cross-contamination from offal will occur directly or indirectly via equipment, air and food handlers in slaughterhouses, retail outlets and residential kitchens.
The study included a total of 7 different hatcheries, 17 different poultry houses on 17 different farms and 9 different slaughterhouses.
Moreover, the park is located near a slaughterhouse, and hence visited by many stray dogs.
The slaughterhouses were visited between 3 and 13 times during the study period.
All other decisions (barns housing animals, slaughterhouses, small factories, all kinds of use of soil etc.) are made by the municipalities (some 25,000 customers).
Cumulus-oocyte complexes were collected from slaughterhouse ovaries, matured, inseminated and subjected to embryo culture in vitro.
The cumulus and oocyte complexes of goat and cattle were collected from a local slaughterhouse, and then matured in vitro.
The swabs were then massaged by hand or in a stomacher bag for 2 min if the latter equipment was available at the slaughterhouse.
