Lauber TB, Connelly NA, Niederdeppe J, Knuth BA. Effects of an Advisory Brochure on Fish Consumption of Urban Anglers in the Great Lakes Region. RISK ANALYSIS : AN OFFICIAL PUBLICATION OF THE SOCIETY FOR RISK ANALYSIS 2018; 38:1405-1421.

Abstract
Past research has suggested that urban anglers are a group at high risk of being exposed to contaminants from fish consumption. Fish consumption advisories have been used in many regions to encourage healthy fish-eating behaviors, but few studies have been designed to assess whether these advisories actually influence behavior as intended. We conducted a large-scale, randomized experiment to test the influence of an advisory brochure on urban anglers' fish consumption. We collected detailed information on anglers' fish consumption in three urban counties in the Great Lakes region in the summers of 2014 and 2015. We provided a treatment group with fish consumption guidelines in an advisory brochure before the summer of 2015 and compared their change in fish consumption to a control group. The brochure led to a reduction in fish consumption for anglers who ate the most fish; these anglers reduced their consumption of high-contaminant purchased fish (by ≥0.2 meals/summer for those in 72nd percentile of fish consumption or above), high-contaminant sport-caught fish (by ≥0.4 meals/summer for those in 87th percentile and above), and low-contaminant sport-caught fish (by ≥0.3 meals/summer by those in 76th percentile and above). The brochure also reduced sport-caught fish consumption among those anglers who exceeded the advisories in 2014 (by 2.0 meals/summer). In addition, the brochure led to small increases in sport-caught fish consumption (0.4-0.6 meals/summer) in urban anglers who ate very little sport-caught fish (≤1 meal/summer).

Desvignes V, Volatier JL, de Bels F, Zeghnoun A, Favrot MC, Marchand P, Le Bizec B, Rivière G, Leblanc JC, Merlo M. Study on polychlorobiphenyl serum levels in French consumers of freshwater fish. THE SCIENCE OF THE TOTAL ENVIRONMENT 2015; 505:623-632. [PMID: 25461065 DOI: 10.1016/j.scitotenv.2014.10.024] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/03/2014] [Revised: 10/07/2014] [Accepted: 10/07/2014] [Indexed: 06/04/2023]
Abstract
INTRODUCTION Polychlorobiphenyls (PCBs) are persistent pollutants that are widespread in the environment and in foodstuffs, particularly in freshwater fish, which frequently exceed the maximum levels set by European regulations. OBJECTIVES First, we describe the consumption of freshwater fish and serum PCB levels in French anglers, a population expected to have the highest level of dietary PCB exposure. Second, we investigated whether there is a statistical relationship between serum PCB levels and the angler consumption of freshwater fish with high PCB bioaccumulation potential (PCB-BP(+) freshwater fish) in order to make recommendations with regard to safe consumption of freshwater fish. METHODS We conducted a survey of anglers from six sites with contrasting PCB contamination levels. The survey included a food consumption frequency questionnaire and blood samples were taken to assess serum PCB levels. We used a regression model to determine the main factors contributing to serum PCB levels. RESULTS Consumption of PCB-BP(+) freshwater fish was relatively infrequent. Serum PCB levels of the study population and of women of childbearing age were in the same range as those observed in the French population and in neighbouring European countries, but higher than in the North American population. The two factors with the highest positive association with serum PCB levels were age (R(2)=61%) and the consumption of PCB-BP(+) freshwater fish (R(2)=2%). Using the regression model, we calculated, for several scenarios depending on the age and gender of the population, the maximum annual frequencies for PCB-BP(+) freshwater fish consumption that do not exceed the critical body burden threshold. CONCLUSION Following the results of this study, the French agency for food, environmental and occupational health and safety (ANSES) issued an opinion and recommended some specific maximum freshwater fish consumption frequencies to protect the French general population.
