Update on EMP(Environmental Monitoring Program)

Unicef SD, 01/07/2015, Copenhagen

(Reminder…) Plant layout: hygienic zones of control

• Sanitary zoning system ≠ mapping hygienic zones of control within the facility

• Plant operations divided into 4 zones based on levelon risk

(Reminder…) Sample location - Sanitary Zoning in a room

(Reminder…) Sanitary Zoning

Zone 1Product contact surfaces (after the lethality or

microbial reduction step) and before the product issealed in the primary packaging

Fillers, hoppers, converor, employee hands, knives…

Zone 2Non - product contact surfaces closely adjacent to the product

contact surfaces exterior, under & framework of equipment, control

panels/buttons, computer screens, maintenance tools, drains located directly under equipment, motors adjacent to lines…

Zone 1Product contact surfaces

Fillers, hoppers, converor, employee hands, knives…

(Reminder…) Sanitary Zoning

Zone 3Non-product contact surfaces (in post-lethality product processingareas), but no closely adjacent to zone 1 surfaces – contamination

possible of zone 2 through employees’ actions or movement of machinery

Floors, walls, ceiling, drains, trolleys, fortlifts, carts, trash containers, pallets, brooms, mops, phones…

Zone 2Non - Product near contact surfaces

exterior, under & framework of equipment…

Zone 1Product contact surfaces

Fillers, hoppers, converor, employee hands, knives…

(Reminder…) Sanitary Zoning

Zone 4Areas ouside of RUF room

Looker room, cafetaria, hallways, loading dock, warehouses, offices area…

Zone 3Other areas within RUF room

Air return covers, phones, forklifts, drains…

Zone 2Non - Product near contact surfaces

exterior, under & framework of equipment…

Zone 1Product contact surfaces

Fillers, hoppers, converor, employee hands, knives…

(Reminder…) Sanitary Zoning

Zone 4

Zone 3

Zone 2

(Reminder…) PEM sampling and testing methods

Advantages of using indicator organisms compared to pathogens:• Cheaper & save time • Can be easily enumerated• Valid representative of pathogens • No need for sophisticated containment facilities/labs (e.g., Bio Safety Level-2)

BUT Indicator organisms are not a substitute for testing for pathogens.

Zone 1:Indicators organisms

Zones 2, 3 & 4:Indicators and pathogens

Zone 1

(Reminder…) Sampling

(Reminder…) Sampling

(Reminder…) Sampling

Zone 4

Zone 3

Zone 2

Zones 2&3: Weekly Both pre-operationally and operationally

for Salmonella: Operational samples taken throughout the

production run (e.g. just after start-up, 3-4h after and at the end)

Sampling time and sites rotated

Zone 1

Zone 4: monthly

(Reminder…) PEM sampling frequency

Zone 1: Weekly Post cleaning Prior to start up As needed for investigational, validation and/or verification purpose

• Flexible & dynamic: follow the data!

• Depends on: - the data

- the size of the facility

- the zone

(Reminder…) Number of PEM samples

Zone 4

Zone 3

Zone 2

Zone 1: Iine & situational dependant(purpose of sampling)

Zones 2&3: generally 10-15 samples/week

Zone 1

Zone 4: generally 5-10 samples/month

TRAINING!!!!

(Reminder…) Establishing your baseline

• Preliminary intensive investigation:– much higher frequency of sampling:

• 25-50 samples or more /zone/day for the first month (rotating shifts)

• Then weekly with same number of samples for the next 2-5 months

– 6 to 12 months of consecutive data needed to establish a baseline/target

• Example: tests <50 cfu for a year with two or three spike readings

=> 50 cfu set as the baseline.

• On-going PEM:– Follow the data!

=> if an area shows positives, then the area should beconsedered as a potential harborage niche or problem area thatrequierts ongoing attention

• Predetermine corrective action to implement in case of pathogenspositive results

– Specific for each zone

– Immediate corrective actions to eliminate the problem

– Verify the elimination of the pathogen

(Reminder…) Corrective actions
