Although cancer in cattle is not treatable, the risk of spreading BLV can be substantially decreased with proper management procedures. Bovine leukemia virus (BLV) is a common viral infection in US cattle, with 39% of beef cow-calf herds and 83% of dairy herds containing BLV-infected cattle.
Can a cow get cancer?
A: Just like us, chickens and cows can develop cancer. But cancer is largely a disease of the aging process, and animals raised for food are slaughtered while they’re young. If, by some chance, a meat product does contain cancerous cells, cooking it will kill them.

What is the most common tumor of cattle?

What happens if you eat a cow with cancer?
We can probably rest assured that meat from cows with cancerous eyes, even served super rare, won’t pass on any traces of cancer along because our digestive systems destroy cells without mercy. Still, eating meat — cancerous or not — poses a risk of exposure to carcinogens.

Chlamydiae are present in many bovine herds, but reports of cases involving farmers suffering from Chlamydia-caused respiratory disorders or asthma-like symptoms are only anecdotal and suggest the zoonotic potential being minimal compared to avian strains.
