It happened early Monday at Central Valley Meat Co. in Kings County.
A spokeswoman for the Californias workplace safety agency, OSHA, says the plant also was investigated for an accident in 2004.
In that incident, a worker accidentally activated a meat grinder while cleaning it and was caught in the machine.
Spokeswoman Krisann Chasarik says the worker was able to switch off the machine before getting sucked in.
The company paid a $1,100 for the failure to lock out the device in that case.
