While
the main sources of chemical residues have been discussed,
there are other areas that may become a problem. Buckshot
contamination of carcasses, while infrequent, continues to
be reported by packers, including finish fed cattle. When
buckshot is found, the animal is condemned. Do not shoot at
any animals and do not allow hunting around your cattle.
Also included is microbial contamination, fluid leakage,
pest control, and water contamination.
Other
diseases such as beef measles, which are not often
discussed, should not be forgotten. Beef measles result
when human tapeworms infect cattle. The problem can be
avoided if cattle feeds are never contaminated with human
feces.
Fluid
leakage from transmissions and transformer fluid poses a
potential problem. Both types of fluid contain chemicals
which can leave a violative residue in slaughtered animals.
Transformers near grain or forage storage areas should be
avoided. Other sources of potential residues could occur
from inappropriate storage of lead batteries, paint,
solvents, or petroleum wastes.
Rodent
and bird control is a continuous battle in most feedlots.
These pests transmit disease and can cause damage to
equipment, including sensitive electrical connections.
Control measures should consider any possible residue as
well as animal and human safety potential. Biosecurity
measures should also include controlling scavengers such as
coyotes, badgers, skunk, etc., as well as deer.
Protection from contamination of the water supply must be a
high priority of every beef operation. Everyone in the beef
operation must be on constant alert for practices, which
could cause contamination of the water supply. If anyone
suspects they have discovered a water supply contamination
source, it must be reported to the manager as soon as
possible.
