Bird Problems and Control Methods for Food Production Facilities
Birds are beautiful in nature, but when they are flying around a food production facility, a host of problems can result.
By R. Brett Madden
Various types of pest birds can impact food plant structures and facility surroundings. Even a single bird that finds its way into a food plant can trigger a host of concerns such as, failed audits, product contamination, plant closure, production stoppage, lost revenues, fines, structural damage, health hazards to occupants and fire hazards.
In most cases, a food plant operation has a bulletproof pest control plan; however, in most cases, birds are always an afterthought in most pest management plans.
Since food processing plants contain areas that have very sensitive environments, birds can introduce various adulterants and harmful contaminants. Birds can cause potential harm to humans due to foodborne illness.
Pest Bird Species
There are four main pest birds: Pigeon, Starling, Sparrow and Seagull. Each one of these birds can cause a host of concerns and issues for food processing facilities. Just one bird can cause catastrophic damage. In most cases, small pest birds such as Sparrows and Starlings can gain access into a facility through a variety of ways:
- Damaged bumpers around truck bay loading dock doors.
- Open doors (seems obvious, but I always find doors wide open during audits).
- General building deficiencies.
Larger birds, such as Pigeons and Seagulls, typically cause more problems around the exterior of a facility on ledges, rooftops, HVAC units, loading docks and related areas.
In either case, these various types of pest birds can cause significant problems on the interior and exterior of food plants.
In most cases, facilities want to reduce as many conducive conditions as they can around and within the facility in a timely fashion. A conducive condition is one whereby due to a building condition, structural design, equipment operation, food or water source, or surrounding conditions (i.e., near a public landfill, raw materials mill or body of water) can attract pest birds to a facility. With each of these conditions, great care must be taken to reduce as many conducive conditions as possible.
From the start, your facility should have a bird management plan of action. For the most part, bird problems should not be left to be handled internally, unless your staff has been properly trained and has a bird management plan in place.
The best prevention strategy is planning and knowledge. Conduct a bird audit and develop a bird management plan before birds get near or inside the facility. The key is to act quickly, as soon as an incident occurs. I find countless times when I am called in to consult or service a food plant, that the birds got into the facility and no one knew what to do, and as a result, the birds remained within the facility for an extended period, thus increasing the risk of exposure. It is always much easier to remove a bird when they are unfamiliar with their surroundings. Whereas, it is much more difficult to remove birds from a facility that has had a long-standing bird problem.
In summary, taking a proactive approach to bird control is the best practice. Reduce food, water and shelter sources (aka conducive conditions) promptly. Pest management programs need to implement a more in-depth section of the program for bird control. Like integrated pest management, bird control should be based upon an integrated method. Each facility will have its unique challenges. As such, each bird management plan needs to be tailored to the specific site. A well designed and balanced, integrated bird management program will provide long-term and cost-efficient bird control.
