1976 initial fish tissue sampling in pa resulted in first consumption advisory

HISTORY

1976 - Initial fish tissue sampling in PA

Resulted in first consumption “advisory”

1976 –79 – Additional special studies

Resulted in first Do Not Eat advice for certain waters

PCBs in excess of 5.0 mg/kg FDA Action Level

1979 – 80 – Began routine, statewide fish tissue monitoring

Whole fish samples

1983 - Began fillet and whole fish sampling at half the sampling

stations to provide data to evaluate health impacts


1976 initial fish tissue sampling in pa resulted in first consumption advisory

HISTORY

1986 - PA Interagency Agreement

Advisory issuance by interagency workgroup

PA Dept of Health

PFBC

DEP (then DER)

Agriculture recently added

They regulate the aquaculture industry

Industry was concerned with advisory issuance for

PFBC hatchery trout


History

HISTORY

1986 - Great Lakes Toxic Substances Control Agreement

Called for common fish consumption advisories

1993 - Great Lakes Sport Fish Consumption Advisory Protocol final

Health, PFBC, and DEP endorse protocol

1997 - Protocol applied to L. Erie & Presque Isle Bay

1998 - Protocol applied statewide

Provides meal-specific consumption advice

Protects sensitive endpoint


1976 initial fish tissue sampling in pa resulted in first consumption advisory

GREAT LAKES PROTOCOL

CONSUMPTION ADVISORY GROUPS


Pcbs in hatchery trout

PCBs IN HATCHERY TROUT

1985 – First sample of PFBC hatchery trout for tissue analysis

“Control” sample for statewide PCB study

PCB in rainbow trout fillets was 0.17 mg/kg

Not of concern - using FDA Action Level of 2.0 mg/kg

1 meal/week under Great Lakes Protocol


Pcbs in hatchery trout1

PCBs IN HATCHERY TROUT

1998 – Tissue samples collected from four PFBC hatcheries

(1 composite of 5 fish)

Concern that some anglers and their families were eating

large amounts of stocked trout

Some reported catching and keeping 100 or more

stocked trout

 Data showed variable concentrations of PCB

3 samples were not of concern

1 warranted a 1 meal/month advisory


Pcbs in hatchery trout2

PCBs IN HATCHERY TROUT

1999 – 8 of 9 trout hatcheries sampled (5 fish)

Data variable

Advisories issued for some fall-stocked fish

2000 – All 9 hatcheries sampled

5 samples of 8 fish, proportioned, 45 total, random

1 hatchery at 1 meal/week

1 hatchery at 1 meal/month (same one as in 1998)


Pcbs in hatchery trout3

PCBs IN HATCHERY TROUT

2001 – April 11

Statewide 1 meal/week advisory issued

All recreationally-caught sport fish

Applies to hatchery trout once released

2001 – All 9 hatcheries sampled

Same randomized, proportional design

No advisories beyond 1 meal/week needed


Pcbs in hatchery trout4

PCBs IN HATCHERY TROUT

2002 –All 8 trout hatcheries sampled

5 samples of 8 fish proportioned

Statistical data evaluation

Upper confidence limit from a 1-tail test used

to determine need for advisories

Same hatchery again warranted 1 meal/month advisory
