Aug 24, 2017

Listeria monocytogenes was a major reason for recalls accounting for over 80% of the total recall cases in 2016. Currently, this trend is continuing, with many recalls due to Listeria monocytogenes. Listeria recalls include: The New York State Department of Agriculture is warning against the consumption of raw milk cheeses from Hillcrest Dairy. The FSIS/USDA announced the recall of Expresco Foods imported, fully cooked chicken skewer products. SunOpta Inc’s subsidiary, Sunrise Growers Inc issued a voluntary recall of frozen organic dark sweet pitted cherry products. Fair Oaks Farms is recalling approximately 1,134 pounds of fully cooked pork sausage patty

Biofilm and food safety: What is important to know?

Biofilms are usually formed in a wet environment in the presence of nutrients. Once biofilms are formed, the cleaning of the food and food contact surfaces becomes more difficult to remove the extracellular polymeric substances (EPS). Therefore, prevention of biofilm formation, using regularly scheduled cleaning and disinfecting protocols is an important first step in preventing cells from attaching and forming biofilms on surfaces. High-temperature washing can reduce the need for the physical force required to remove biofilms. Chemical cleaners suspend and dissolve food residues by decreasing surface tension, emulsifying fats, and denaturing proteins.

Since our last report on July 23, there have been several additional recalls associated with the outbreak of Salmonella in papayas. Grande Produce issued a recall for its imported papayas from the Carica de Campeche farm in Mexico. This farm seems to be the primary source of the outbreak. A second papaya recall was issued by Agroson’s LLC, for more than 2,000 boxes of Cavi-brand Maradol Papaya imported from the same Mexico farm. A few days later, a third papaya recall was issued by Freshtex Produce. A total, of 141 people infected with the outbreak strains of Salmonella Kiambu (51) or Salmonella Thompson (90), in 19 states

Aug 9, 2017

Good Food Concepts, LLC., a Colorado Springs, Colorado recalled 1,290 pounds of raw beef products, processed Aug. 3 and Aug. 4, 2017, due to potential contamination with E. coli O26. The contamination was discovered on Aug 5, 2017, by the company who had notified the FSIS inspection. A lot of carcasses received from Callicrate Ranch on July 31, 2017, were found to be contaminated with STEC (Shiga toxin producing E. coli) E. coli O26. Good Food Concepts company and FSIS are concerned that some beef may be frozen and in consumers’ freezers.

Biofilm and food safety: What is important to know?

By Dr. Bassam A. Annous and Dr. Ruth Eden

In nature, most bacteria do not exist as suspended (planktonic-free floating) cells. Bacteria live in a group (mass of bacterial cells) attached to each other and to surfaces, in a biofilm form. A biofilm is as a complex community of microorganisms, embedded in self-created extracellular polymeric substances (EPS). Therefore, the biofilm is a microbial population adherent to each other and to surfaces or interfaces enclosed in the matrix. In this complex biofilm network of EPS, the bacterial cells perform less as individual cells and more as a collective living system, frequently creating channels to deliver nutrients and water to the cells located inside the biofilm.

A Novel Concentration Device for the Detection of Food Pathogens

Jul 30, 2017

A new, simple novel device to concentrate and detect food pathogens shows that in volumes up to 250 mL, 55%-91% of bacteria were captured by the device in 6-7 hours. The technique employs polymer (polydimethylsiloxane) tubes (1.02 mm in diameter) coated with an antibody. The test sample is circulating through the antibody coated tubes. As a result, the pathogens present in the sample are concentrated and accumulated in the tubes. This concentration step results in a higher concentration of the pathogens in a small volume of liquid.

Jul 23, 2017

An outbreak of Salmonella Kiambu in yellow Maradol papaya has sickened 47 individuals from 12 states and is being investigated by the CDC, FDA and public health officials in multiple states. Whole genomic sequencing shows that the Salmonella Kiambu isolated from the infected people is genetically closely related, and therefore, are more likely to share the same source of infection. More than third of the affected people were hospitalized, and one death was reported in New York City.

FSMA and Pathogen Environmental Monitoring (PEM) Programs: Where are we?

get_the_title()

Jul 18, 2017

Environmental monitoring required under CFR 21 section 117.165 and the FDA Final Rule for Preventive Controls for Human Food. Its purpose is to verify the implementation and effectiveness of the preventive controls put in place. Most food companies need to comply with these rules now or in the very near future. The reason for having a PEM program is to identify problem areas in the manufacturing facility where pathogens can harbor and become a source of contamination (“niches”) and assess the effectiveness of the sanitation programs. It may include pathogens or indicator organisms, depending on the products being manufactured. The program should encourage finding locations that will yield positive pathogen results.

Recalls due to Labeling Mistakes – The #1 Reason for Food Recalls

get_the_title()

Jul 11, 2017

Although there was an extremely high number of recalls due to Listeria monocytogenes in the past three months, the majority of the FDA recalls were due to allergens many caused by mislabeling.  Undeclared allergens accounted for about 90% of labeling related recalls. The Food Allergen Labeling and Consumer Protection Act of 2004 requires that packaged food labels include declarations of the eight major food allergens: eggs, milk, wheat, peanuts, soybeans, tree nuts, fish and crustacean shellfish.   Allergens are unique in food safety as they...

Recalls and Outbreaks due to Food Pathogens: Is there a connection?

Jul 7, 2017

Most food recalls in the U.S. are due to Listeria. Food Safety Tech has reported that in 2016 about 550 food products were recalled in the US. Of the recalled products, 275 were due to microbial contamination. Of the recalls, due to microbial contamination, 65% were due to Listeria monocytogenes. Salmonella accounted for 21% of the recalls, while E. coli accounted for only 3% of the recalls. However, there were more Salmonella outbreaks in 2016 than Listeria outbreaks.
