A

condemn the carcass

-abnormal pigment
-post-mortem changes

36
Q

should ratite carcasses with parasites be condemned?

only when there is generalized infestation of parasites that are not trimmable

carcasses that have wounds infested with maggots should be segregated and sent to the lab for diagnostic confirmation

37
Q

FSIS Directive 6000.1

A

Responsibilities Related to Foreign Animal Diseases and Reportable Conditions

38
Q

what can cause abnormalities of the long bones in ratites?

visceral gout

40
Q

categories of process controls for salmonella testing in production establishments

A

Category 1 (consistent process control)
-establishments with positive Salmonella results at 50% or less of the performance standard in last 2 sample sets - BEST
Category 2T (variable process control but transitioning towards consistent process control)

Q

What is the Listeria Rule?

A

Listeria monocytogenes (Lm) is a hazard that establishments producing post-lethality exposed RTE meat and poultry products must control through their HACCP plans or prevent in their processing environment through their Sanitation SOP or other prerequisite programs

N/A

53
Q

What is a RTE product?

A

a meat or poultry product that is in a form that is edible without additional preparation to achieve food safety (ie has been cooked, dried, fermented, etc.)

  • FSIS considers products in the Fully Cooked - Not Shelf Stable HACCP category to be RTE
54
Q

FSIS considers a product to be post-lethality exposed if it is RTE and meets the following criteria:

A
  • the product is exposed to the environment of the establishment after the lethality step
  • the product doesn’t remain in a cooking bag and it comes in contact with food contact surfaces, brine, or other environmental conditions during cooling, processing, slicing, or packaging steps
55
Q

FSIS considers a product to be non-post lethality exposed if:

A

-product is cooked in a bag and remains in the cooking bag until it leaves the establishment
-product is treated with a process (ie. high pressure processing) that achieves a full lethality in the product once it is in its final packaging
-product is hot filled at a temp sufficient to achieve full lethality of the product

56
Q

A

T

57
Q

A

Product produced from “clean-up to clean-up” for RTE products
-usually produced on the same line/in the same room

58
Q

A

Yes

59
Q

If a product passes over a surface that tests positive for Listeria spp (not Lm), is the product considered adulterated?

A

No

And the establishment is NOT required to confirm whether the sample is positive for Lm; however they are required to take CAs

60
Q

Listeria control measures (“alternatives”)

- proper sanitation

61
