Fruits and vegetables are an important part of a healthy diet. Your local markets carry a wide variety of nutritious fresh fruits and vegetables. However, harmful bacteria that may be in the soil or water where produce grows can come in contact with fruits and vegetables and contaminate them. Fresh produce may also become contaminated after it is harvested, such as during storage or preparation.

Eating contaminated produce can lead to foodborne illness, often called “food poisoning.” So as you enjoy fresh produce, follow these safe handling tips to help protect you and your family.

PT Farm, LLC, a North Haverhill, N.H. establishment, is recalling approximately 8,800 pounds of raw beef products that may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

Food Poisoning Bulletin

An E. coli outbreak linked to ground beef produced by PT Farm of North Haverhill, NH has sickened 14 people in four states, hospitalizing four of them. A recall has been issued for beef products sold under the brand names PT Farms, Chestnut Farms, Robie Farms and Miles Smith Farm. Consumers who have purchased this meat should not eat it as E. coli can cause serious illness and death

South Australian health authorities have detected Salmonella on rockmelons supplied by a Northern Territory rockmelon grower.

The link comes after a spike in Salmonella Hvittingfoss cases, a rare strain of Salmonella, across a number of states in the past weeks, with 86 cases reported nationally, 43 of them in NSW.

Following the positive test results, confirmed by SA Health on Tuesday 2 August, the company ‘Red Dirt’ has said it will undertake a trade level recall of their product, which means it will be removed from the supply chain so consumers can be assured rockmelons currently available on shelves are not implicated in this outbreak.

The NSW Food Authority and the local NT health agency are working with the company in resolving the issue.

Further, as a precautionary measure, the NSW Food Authority advises anyone who may have rockmelon in their home and is unsure of its origin not to consume the product.

Ottawa, August 2, 2016 – The food recall warning issued on August 1, 2016 has been updated to include additional product information. This additional information was identified during the Canadian Food Inspection Agency’s (CFIA) food safety investigation.

La Poissonnerie Cowie Inc. is recalling Blue Marlin and Vegetables Skewers packed by La Poissonnerie Cowie Inc. from the marketplace due to elevated levels of histamine. Consumers should not consume and distributors, retailers and food service establishments such as hotels, restaurants, cafeterias, hospitals and nursing homes should not sell or use the recalled products described in the link.

Please note that the individual 180 g blue marlin and vegetables skewers were also sold at retail fresh, marinated, unlabelled, and in bulk without the original packaging. Consumers who are unsure if they have purchased the affected blue marlin and vegetables skewers are advised to contact their retailer.

Emerging evidence suggests there is a link between a type of Salmonella (SaintPaul) and consumption of rockmelons.

There have been a number of cases of food poisoning from Salmonella and rockmelons. Overseas evidence suggests contaminated water, fertiliser, contact with pests/animals or insufficient cleaning of rockmelons prior to sale could be contributing factors to rockmelons becoming contaminated with Salmonella.

A NSW Health study showed that a number of NSW consumers fell ill with Salmonella poisoning after eating rockmelons. The study suggests whole and sliced rockmelons could contain Salmonella.

Rockmelons have been linked to Salmonella poisonings in the past, notably the United States during the 1950s, 1960s and in 2002.

As a result, the NSW Food Authority is advising consumers to take some simple precautions to minimise the risk from Salmonella in rockmelons.

We conducted a national census survey of egg product plants (n = 57) to obtain information on the technological and food safety practices of the egg products industry and to assess changes in these practices from 2004 to 2014. The questionnaire asked about operational and sanitation practices, microbiological testing practices, food safety training for employees, other food safety issues, and plant characteristics. The findings suggest that improvements were made in the industry’s use of food safety technologies and practices between 2004 and 2014. The percentage of plants using advanced pasteurization technology and an integrated, computerized processing system increased by almost 30 percentage points. Over 90% of plants voluntarily use a written hazard analysis and critical control point (HACCP) plan to address food safety for at least one production step. Further, 90% of plants have management employees who are trained in a written HACCP plan. Most plants (93%) conduct voluntary microbiological testing. The percentage of plants conducting this testing on egg products before pasteurization has increased by almost 30 percentage points since 2004. The survey findings identify strengths and weaknesses in egg product plants’ food safety practices and can be used to guide regulatory policymaking and to conduct required regulatory impact analysis of potential regulations.

A total of 44 samples of salmon, pangasius (shark catfish), shrimps, and oysters were tested for the presence of Escherichia coli, enterococci, Pseudomonas aeruginosa, and Staphylococcus aureus, which are indicator organisms commonly used in programs to monitor antibiotic resistance. The isolated bacterial strains, confirmed by matrix-assisted laser desorption ionization time-of-flight mass spectroscopy, were tested against a panel of 29 antimicrobial agents to obtain MICs. Across the four sample types, Enterococcus faecalis (59%) was most common, followed by E. coli (55%), P. aeruginosa (27%), and S. aureus (9%). All bacterial species were resistant to some antibiotics. The highest rates of resistance were in E. faecalis to tetracycline (16%), in E. coli to ciprofloxacin (22%), and in S. aureus to penicillin (56%). Antibiotic resistance was found among all sample types, but salmon and oysters were less burdened than were shrimps and pangasius. Multidrug-resistant (MDR) strains were exclusively found in shrimps and pangasius: 17% of pangasius samples (MDR E. coli and S. aureus) and 64% of shrimps (MDR E. coli, E. faecalis, and S. aureus). Two of these MDR E. coli isolates from shrimps (one from an organic sample) were resistant to seven antimicrobial agents. Based on these findings, E. coli in pangasius, shrimps, and oysters, E. faecalis in pangasius, shrimps, and salmon, and P. aeruginosa in pangasius and shrimps are potential candidates for programs monitoring antimicrobial resistance. Enrichment methods for the detection of MDR bacteria of special public health concern, such as methicillin-resistant S. aureus and E. coli producing extended-spectrum β-lactamases and carbapenemases, should be implemented.

Outbreak data have been used to estimate the proportion of illnesses attributable to different foods. Applying outbreak-based attribution estimates to nonoutbreak foodborne illnesses requires an assumption of similar exposure pathways for outbreak and sporadic illnesses. This assumption cannot be tested, but other comparisons can assess its veracity. Our study compares demographic, clinical, temporal, and geographic characteristics of outbreak and sporadic illnesses from Campylobacter, Escherichia coli O157, Listeria, and Salmonella bacteria ascertained by the Foodborne Diseases Active Surveillance Network (FoodNet). Differences among FoodNet sites in outbreak and sporadic illnesses might reflect differences in surveillance practices. For Campylobacter, Listeria, and Escherichia coli O157, outbreak and sporadic illnesses are similar for severity, sex, and age. For Salmonella, outbreak and sporadic illnesses are similar for severity and sex. Nevertheless, the percentage of outbreak illnesses in the youngest age category was lower. Therefore, we do not reject the assumption that outbreak and sporadic illnesses are similar.

Prepacked ready-to-eat mixed ingredient salads (RTE salads) are readily available whole meals that include a variety of ingredients such as raw vegetables, cooked meat, and pasta. As part of a trend toward healthy convenience foods, RTE salads have become an increasingly popular product among consumers. However, data on the incidence of foodborne pathogens in RTE salads are scarce. In this study, the microbiological safety of 141 RTE salads containing chicken, ham, or smoked salmon was investigated. Salad samples were collected at retail and analyzed using standard methods for Listeria monocytogenes, Shiga toxin–producing Escherichia coli (STEC), pathogenic Yersinia enterocolitica, Salmonella, and Campylobacter spp.L. monocytogenes was isolated from two (1.4%) of the RTE salad samples. Seven (5.0%) of the samples were positive for the ail gene (present in all human pathogenic Y. enterocolitica isolates) and three (2.1%) of the samples were positive for the Shiga toxin genes stx ₁ and/or stx ₂. However, no strains of pathogenic Y.enterocolitica or STEC were isolated. Thus, pathogens were found or suspected in almost 1 of 10 RTE salads investigated, and pathogenic bacteria probably are present in various RTE salads from retail premises in Sweden. Because RTE salads are intended to be consumed without heat treatment, control of the ingredients and production hygiene is essential to maintain consumer safety. The recommended maximum storage temperature for RTE salads varies among countries but can be up to 8°C (e.g., in Sweden). Even during a short shelf life (3 to 5 days), storage at 8°C can enable growth of psychrotrophs such as L. monocytogenes and Y. enterocolitica. The maximum storage temperature should therefore be reduced.

Previous research has shown that many consumers do not follow recommended food safety practices for cooking poultry and eggs, which can lead to exposure to Salmonella and Campylobacter. Past research has been done primarily through surveys and interviews, rather than observations. The objective of this project was to determine through observations whether consumers follow food safety guidelines. Consumers (n = 101) divided among three locations (Manhattan, KS; Kansas City, MO area; and Nashville, TN) were observed as they prepared a baked whole chicken breast, a pan-fried ground turkey patty, a fried egg, and scrambled eggs. The end point temperature for the cooked products was taken (outside the view of consumers) within 30 s after the consumers indicated they were finished cooking. Thermometer use while cooking was low, although marginally higher than that of some previous studies: only 37% of consumers used a thermometer for chicken breasts and only 22% for turkey patties. No one used a thermometer for fried or scrambled eggs. Only 77% of the chicken and 69% of the turkey was cooked to a safe temperature (165°F [74°C]), and 77% of scrambled and 49% of fried eggs reached a safe temperature (160°F [71°C]). Safe hand washing was noted in only 40% of respondents after handling the chicken breast and 44% after handling the ground turkey patty. This value decreased to 15% after handling raw eggs for fried eggs and to 17% for scrambled eggs. These results show that there is a high prevalence of unsafe behaviors (undercooking and poor hand washing technique) when cooking poultry and eggs and a great need for improvement in consumer behavior with poultry and eggs.
