Cleaning a Schedule for a fish plant

Cleaning Schedule for a fish plant

Before start:

a)   Requires thorough cleaning of all machinery, tanks, tables, floor, walls and ceilings to remove dirt and bacteria-bearing dust.

b)   Disinfect all working surfaces with 25 ppm chlorine solution.

Continuous cleaning

Tables, floors and other working surfaces should be sloped to effect continuous draining to prevent standing water which builds up bacteria populations.

a)   Rinse each Box and tub each time after emptied.

Morning clean-up:

a)   Before operations start for the day, rinse all working surfaces with cold water containing 5-10 ppm residual free chlorine, as a precaution to remove any cleanser and sanitizing agent left from the previous clean-up.

Each work break:

a)   Remove all static material from working surfaces; in other words  bits of fish, gut, etc.,

b)   To remove all slime and blood, flush and rinse all working surfaces with water containing 5 ppm residual free chlorine.

c)   remove all waste from the floor.

Lunch break

a)   Clear of all fish.

b)   Remove all gut from the working surfaces.

c)   remove all waste from floor.

d)   Drain washing tanks.

e)   Rinse all working surfaces, wash tanks, tubs, carts and floor with high pressure hose, using 25ppm chlorine solution to cut slime and lower bacterial numbers.

f)    At end of lunch break, flush all surfaces with 5 ppm free chloride solution to clean away all excess chloride.

End of day clean-up:

a)   Rinse all working surfaces with cold water containing  25 ppm chlorine

b)   Remove cowlings to expose all machinery that comes in contact with fish.

c)   Scrub all working areas with cleanser and scrub brush, or use a high pressure detergent dispenser.

d)   Scrub all cutting boards and place in a tank containing 100-ppm chlorine solution.

e)   Rinse all areas with stronger chlorine solution of 30-50 ppm.  Allow 10 minutes contact time.

f)    Scrub down floors and walls.  A large floor broom with stiff bristles is effective for this.

g)   Rinse all surfaces with clean water of 5-ppm chlorine solution.  This low level of chlorine will prevent corrosion of metal surfaces.

End of week:

a)   In certain areas and on equipment such as fish carts and chutes a hard dried deposit tends to build up.  This is the place where jelly or foam additives in harsh detergents may be useful as this is difficult to remove by using ordinary detergents and a scrub brush.  If such detergents are available, they should be used as follows:

1)   Rinse away all loses material, mix chemical in the tank following manufacturers recommendations.

2)   Spray all hard-to-clean areas and other surfaces which have a heavy deposit of static material.

3)   Let it stand for 30 minutes to an hour, then rinse thoroughly.  Strong alkali detergents will corrode metal surfaces.

4)   It may be necessary to use an acid detergent once a month or several times a season.  Acid detergents remove all mineral deposits. Do not use acid detergents on concrete floors, as acid will pit the concrete.
