Spray Applications

The spray application of two commercial decontaminating agents for reducing bacterial populations associated with fecal contamination on beef was examined in two separate experiments. Individual pieces of prerigor lean beef tissue were inoculated with fresh bovine feces and subjected to a 15-s spray wash (75 lb/in2, 20°C) with water or various concentrations of Carnatrol™, composed of copper sulfate pentahydrate, or Timsen™, 40% N-alkyldimethylbenzylammonium chloride in 60% stabilized urea, and stored under refrigerated (5°C) conditions. When Carnatrol™ was applied to beef tissue at 20, 40, and 80 ppm, bacterial populations were not statistically different (P ≥ 0.05) than water-treated populations at days 0, 1, and 2. When Carnatrol™ was applied to tissues at 160 ppm, bacterial populations were statistically different (P ≤ 0.05) from water-treated tissue on all of the days examined; however, reductions were not greater than 0.58, 0.42, and 0.35 log CFU/cm2 at days 0, 1, and 2, respectively. Remaining bacterial populations resulting from spray applications of Timsen™ to tissues at 200, 400, and 800 ppm were not statistically different than remaining bacterial populations of water-treated tissues at days 0, 1, 2, or 3. Reductions in bacterial populations associated with Timsen™ were no greater than 0.40 log CFU/cm2 on any of the days examined. This study demonstrates that under conditions used in this study, spray washes with either of the two commercially available decontaminating agents were no more effective than water washes for reducing bacterial populations associated with fecal contamination on beef tissue.

Effects of herbicide combinations on aquatic invertebrates were evaluated in Inglis Reservoir, which is located in west coastal Florida. The addition of 6,7-dihydrodipyrido [1,2-a: 2′1′-c]pyrazinediium ion (diquat) plus the triethanolamine complex of copper sulfate (TAC) and diquat plus copper sulfate pentahydrate (CSP) for control of hydrilla (Hydrilla verticillata Casp.) decreased the number of invertebrates inhabiting the treated areas. The diquat plus CSP combination exerted the greatest effect upon invertebrate numbers. Both herbicide combinations, however, did alter significantly the number of taxonomic groups in the areas. Invertebrate declines were due more generally to resultant habitat changes (i.e., loss of hydrilla) than to direct herbicide toxicity. The response of fish to the effects of the herbicide treatments on invertebrates could be ascribed to dietary changes, decreased growth rates, and possible mortality.
