The A143 at Billingford was closed for nearly an hour after a lorry shed its load of chicken carcasses and offal.
It happened just before 8pm on Wednesday.
Between 75-100 kilogrammes of goods fell off the lorry across both lanes. Norfolk Police, as well as a fire crew from Diss, attended the incident.
The A143 was closed while emergency services bagged the offal for the Environment Agency and washed the road.
The road reopened shortly after 9pm.
