Does Costco rotisserie chicken contain antibiotics?
As part of its animal welfare policy, Costco has signaled that it intends to
reduce antibiotic use.
A survey it sent to its chicken suppliers found that 97 percent of its Kirkland Signature products (including rotisserie chickens) were raised without the “
routine use” of antibiotics that are also used to treat people. However, “routine use” is undefined. If no routine use means that antibiotics are only administered once per flock, that would still mean all birds in the flock received antibiotics. Costco has
resisted requests from their shareholders to publish quantitative data showing progress away from the overall use of antibiotics in their chickens. Costco has not released an analysis of their chicken products to support the survey’s results.
Does Costco rotisserie chicken contain hormones?
The U.S. Department of Agriculture prohibits the use of hormones in raising any poultry in the United States. Therefore, the chickens that are slaughtered to become Costco’s rotisserie chickens do not contain any added hormones.
Why are Costco chickens so big?
The average Costco rotisserie chicken weighs three pounds fully cooked. The birds raised for Costco are broiler chickens who have been
genetically modified through breeding to grow very large, very quickly. About 100 years ago in 1925, chickens lived for 112 days before being slaughtered at 2.5 pounds. Modern chickens, such as those raised by Costco, are slaughtered at only 47 days but at 5 pounds
weigh more than double what their ancestors weighed at slaughter.
Costco rotisserie chickens are what the industry calls “small birds.”
Hybrid breeding techniques have also produced “heavy birds,” who are 8-9 pounds when alive and are usually sold cut up as chicken products. All of these birds, large and small, are raised by the tens of thousands on
modern chicken farms better known as “
factory farms.”
