Hannaford Supermarkets and Superior Nut and Candy are recalling pine nuts because they may be contaminated with Salmonella bacteria. No illnesses have been reported to date in connection with the consumption of this product.
Routine testing by the FDA discovered the pathogenic bacteria in one package of the pine nuts.
Raw milk from Apple Valley Creamery in East Berlin, Pennsylvania has been recalled for Campylobacter contamination, according to the Pennsylvania Department of Agriculture. The samples taken January 8, 2015 tested positive for the pathogenic bacteria.
If you purchased this milk, discard it immediately and do not drink it. The milk is sold at an on-farm retail store and through home delivery. Stores in Adams, Cumberland, Dauphin, and Perry also carry the creamery’s products. The raw milk is sold under the Apple Valley Creamery label in half gallon and quart glass containers with sell-by dates of February 9 and February 11, 2015. The dairy cannot sell any more raw milk until health department officials clear the facility.
Campylobacteriosis is an emerging foodborne illness of high relevance and implication for public health and is frequently linked to the consumption of inadequately prepared poultry. Despite extensive scientific efforts to find possibilities to eradicate the bacteria at the production stage and particular measures currently implemented, it has not been possible to provide Campylobacter-free poultry to the consumer. Therefore, it is important to inform consumers about the risk and appropriate mitigation measures. The primary goal of this study was to investigate Swiss consumers’ knowledge of pathogenic bacteria and mitigation measures and domestic food safety behaviour. Thus, the relevant information that should be included in risk communications could be identified. The secondary goal was to identify target groups for risk communication who exhibit particularly unsafe behaviour when preparing poultry. These research questions were investigated in a mixed-method study, combining findings from a qualitative pre-study with the quantitative findings from a survey administered to a large sample of people who occasionally cook poultry (N = 465). The core of the questionnaire was behaviour and knowledge scales, as well as variables assessing risk perception and cooking experiences. Despite a high overall level of knowledge about pathogenic bacteria in poultry and mitigation measures, prevalent misconceptions and knowledge gaps were uncovered. Major violations of food safety behaviour were reported related to avoiding cross-contamination. Lack of specific knowledge and personal risk perception were estimated to be central reasons for violations of food safety behaviour during poultry preparation. Three different consumer groups were identified and analysed according to socio-demographics and socio-psychological variables: unsafe cooks, who reported overall unsafe behaviour, intermediate cooks, who reported some unsafe behaviour, and safe cooks, who reported only little food safety violations. As a last step, the study’s findings were discussed in terms of implications for further research and risk communication practice by isolating the most important knowledge and behaviour aspects. Furthermore, targeted risk communication strategies are considered for the three different target groups.
The purpose of this study was to investigate the effectiveness of ultraviolet-C (UV-C) light inactivation as affected by the location of pathogens on the surface and at stem scars of whole grape tomatoes. A mixed bacterial cocktail containing a three strain mixture of Escherichia coli O157:H7 (C9490, E02128 and F00475) and a three serotype mixture of Salmonella enterica (S. Montevideo G4639, S. Newport H1275, and S. Stanley H0558) were used. Tomatoes were spot inoculated using approximately 100 μL of inocula to achieve a population of about 107±1 CFU/tomato. Additionally, the effects of treatment on color, texture, lycopene content, and background microbial loads during post UV-C storage at 4 °C for 21 days were determined. Results showed that UV-C doses of 0.60–6.0 kJ/m2 resulted in 2.3–3.5 log CFU per fruit reduction of E. coli O157:H7 compared to 2.15–3.1 log CFU per fruit reduction for Salmonella on the surfaces. Under the same conditions, log reductions achieved at stem scar were 1.7–3.2 logs CFU for E. coli O157:H7 and 1.9–2.8 logs CFU for Salmonella. The treatment was effective in controlling native microbial loads during storage at 4 °C as the total aerobic mesophilic organisms (PCA) and anaerobic lactic acid bacteria (LAB) counts of treated tomatoes were significantly (p < 0.05) lower during storage compared to the control group and the yeast and mold populations were reduced significantly below the detection limit. Furthermore, the firmness of tomato and its color was not affected by the UV-C doses during storage. UV-C radiation could potentially be used for sanitizing fresh tomatoes and extending shelf-life. The results of this study indicate that the specific location of pathogens on the produce influences the effectiveness of UV-C treatment, which should be taken into consideration for the design of UV-C systems for produce sanitization.
