Regarding to the pest control about preventing access: we should install the plastic curtain at the open door and the door should be closed immediately after use.
Yes doors must be closed when not in use. Is your problem more that the warehouse employees like to keep the doors open all the time for convenience? If so it is a management issue and the strict implementation of this rule would certainly help with your problem.
Plastic strip curtains make access in and out a little more difficult, but you get used to it after a while. I’m sure if you employ this system it would further reduce insects coming into your factory.
A better alternative is self-opening / closing doors. These are more expensive, but are much more effective as door opening and closing is taken out of the employee’s hands. And the doors are only open when and for as long as is necessary. I understand this may not be possible due to cost. Auto doors with strip curtains would be even better.
How are your electric fly killers positioned? Do not let them be visible to the outside as they encourage insects into the factory.
You say you have installed strip curtains on most other doors, I’m guessing these doors do not open as much as the warehouse, so based on risk what is the logic?
Your pest control report indicates a huge amount of insect activity and if I were your customer I would be very concerned, especially as insects can be seen in large numbers on the floor and in product (photos). Covers over the lines will reduce product contamination, but it’s not getting to the root cause and therefore can only be effective to a certain level. Pest prevention is the key.
One other question do you or can you invert the cans before finished packing? This could be a final control measure.
I hope this helps; you appear to have a serious issue. And I think you need to address this for customer satisfaction and also I imagine to achieve your goal of ISO 22000 certification.
Has anybody else got a comment on this?
