Plant Manager Survival Guide

The 30 critical mistakes to avoid — written from the floor, not the textbook.

Category 1 Food Safety & Regulatory Failures
1

Treating QA as a department instead of a partner

If QA feels pressured by production, problems get hidden instead of fixed.

Rule: QA holds product — no exceptions.
2

Assuming “we’ve always done it this way” is compliant

Legacy practices often predate FSMA updates. Auditors don’t care about history.

3

Waiting until inspection week to clean up

FDA inspectors see beyond surface cleanliness immediately. They look for systems, not shine.

4

Ignoring small GMP violations

Hairnet slips, open drinks, jewelry — these are early warning signs of culture breakdown.

5

Allowing undocumented process changes

Small formula, supplier, or equipment changes cause huge recall risks.

6

Thinking sifting alone equals full foreign material control

Sifting catches metal particles, but does nothing for plastic, wood, rubber, or glass below mesh size.

7

Treating allergen changeovers like standard cleaning

Allergen recalls are the fastest way to destroy trust and profit.

8

Not personally understanding your HACCP CCPs

If you can’t explain every CCP clearly, you’re exposed during audits.

9

Backfilling records at end of shift

Auditors detect this instantly from handwriting patterns and timestamps.

10

Letting corrective actions stop at “retrained employee”

That’s not a root cause — it’s avoidance.

Category 2 Dry Mix Specific Failures
11

Underestimating combustible dust

The dust you barely see can still explode.

12

Using compressed air carelessly

It redistributes allergens and ignitable dust into the air.

13

Over-mixing blends

More mixing does not equal better uniformity. Over-mixing causes segregation.

14

Too many post-blend transfers

Every movement increases separation risk.

15

Ignoring humidity trends

Dry mix plants fail slowly from moisture — not suddenly.

16

Allowing wet cleaning without full drying

Moisture + dry powder = microbial risk and caking failures.

17

Not checking blender wear

Worn ribbons quietly destroy uniformity long before obvious failure.

18

Poor grounding of powder equipment

Static causes dust ignition and product cling.

19

Letting ingredient bags pile near blending

Cross-contact and pest risk increases quickly.

20

Treating rework casually

Rework is one of the biggest hidden contamination pathways.

Category 3 People & Culture Mistakes
21

Spending all day in the office

If you’re not visible, standards drop instantly.

22

Only walking first shift

Problems live on nights and weekends.

23

Focusing only on output numbers

Speed hides defects.

24

Ignoring sanitation crew morale

Sanitation is your largest food safety control.

25

Protecting weak supervisors too long

Bad supervisors create silent compliance failures.

26

Correcting operators publicly

Respect drives compliance more than fear.

27

Skipping one-on-ones with direct reports

Misalignment grows quietly until crisis.

Category 4 Maintenance & Facility Traps
28

Allowing “temporary fixes” to become permanent

Tape, zip ties, and temporary guards become audit findings.

29

Maintenance not cleaning after work

Metal shavings and debris are major audit triggers.

30

Delaying small repairs

Small leaks become mold, pests, and citations faster than expected.

The Five Deadliest Early Mistakes

If you avoid only five things, avoid these:

1 Weak allergen changeovers
2 Poor documentation discipline
3 Dry mix dust accumulation
4 Production pressure overriding QA
5 Lack of floor visibility from leadership
