Research – Discerning microbial and quality attributes of differently slaughtered and dead poultry meat

Wiley Online

Abstract

Globally, various methods of slaughtering have been practiced for the production of chicken meat. Among these methods, Halal slaughtering is implemented to produce Halal chicken. This method involves cutting the throat to bring the animal toward quick death without anguishing. Additionally, Halal slaughtering also favours rapid blood flow and more bleeding. Slaughtering methods are concorded with composition, quality, and microbial safety of meat, mediated by varied blood retention. Accordingly, the present work was aimed to explicate the effect of various slaughtering methods on quality and safety of broiler meat. Results revealed that significant compositional changes were observed in meat obtained from different slaughtering methods. Additionally, Halal‐slaughtered meat showed less nitrogenous losses (TVBN = 9.81 mgN/100 g), high water holding capacity (72.02%), better shear‐force value (21.37 g), and normal color (L* = 48.59, a* = 0.85, b* = 11.56) as compared to other slaughtering methods and dead meat. Additionally, Halal‐slaughtered meat contained less number of total plate count (4.28 log10CFU/g), Enterobacteriaceae count (3.12 log10CFU/g), Salmonella (2.74 log10CFU/g), and E. coli (2.78 log10CFU/g) counts in comparison with the other slaughtering methods and dead meat samples. Findings of the study indicate that slaughtering methods significantly influence the quality and microbial status of broiler meat.

Practical applications

In recent years, the international market for meat obtained from animals/birds slaughtered by using various religious methods has become important for supplying the desired meat globally. Although several studies have been conducted in this domain but most of the published data mainly emphasise the work related to the use of conventional slaughtering methods with limited comparison to religious slaughtering methods. However, some projects have also addressed the issues related to the impact of slaughtering methods on meat quality. Discussion related to religious slaughtering has been in progress around the world. Accordingly, the present study was conducted in this regard for providing some more information and facilitating the existing and upcoming discussions on the merits and demerits of several slaughtering methods with special reference to meat quality and safety.

Research – Listeria monocytogenes risk associated with chicken at slaughter and biocontrol with three new bacteriophages

Wiley Online

Abstract

The aim of this study was to isolate Listeria monocytogenes from chicken neck skins and lytic bacteriophages from poultry slaughterhouse wastewaters, and following the characterization of the isolates, biocontrol of L. monocytogenes was investigated on chicken drumsticks with the isolated phages. L. monocytogenes prevalence was detected 12.3% in the chicken samples and the dominant serotype was determined as 1/2a (92.5%). Expression levels of major virulence genes were revealed by real‐time RT‐PCR. Ten different DNA profiles were detected by ERIC‐PCR fingerprinting. According to the MIC results, LM‐P75 was defined as MDR by showing resistance to antibiotics in six different groups. Besides, five lytic listeriophages were isolated from wastewaters and treated with Cla1 and Sac1. Taking EoP, TEM, in vitro, and in vivo analyses results into consideration, three bacteriophages were used for the biocontrol assay. The application of the bacteriophages on drumsticks achieved a reduction up to 3.3 log CFU/ml in L. monocytogenes count in 3 hr of incubation at 4°C.

Practical applications

Our results showed that in spite of the developments in hygiene practices during slaughtering, chicken meat is still a potential source for L. monocytogenes. On the other hand, the phage cocktail that used in this study can be an effective tool to reduce L. monocytogenes in chicken carcasses at final wash or at cooling step in poultry slaughtering process, as well as in decontamination of chicken meat parts.

USA – Environmental Sampling of Hatchery Detects Salmonella During 2018 Outbreaks

Contagion Live

 

The United States has seen 70 Salmonella outbreaks linked to contact with live poultry between 2000-2017, resulting in 4794 cases, according to reports from the US Centers for Disease Control and Prevention (CDC). The most recent surveillance reports indicate that live poultry-related outbreaks are on the rise with 9 outbreaks reported in 2016 and 10 reported in 2017.

Despite the frequency of live poultry-related outbreaks, environmental sampling is not routinely conducted during outbreak investigations. As a result, the source of the outbreak is rarely identified.

However, on June 12, 2018, the Michigan Department of Health and Human Services (MHHS) requested assistance from the CDC to investigate Salmonellarisk factors at a mail-order hatchery. The findings of the investigation were published in the CDC’s Morbidity and Mortality Weekly Report.

Canada -Raw milk believed to be source of E. coli contamination in cheese: BCCDC

Cowichan Valley Citizen

The BC Centre for Disease Control (BCCDC) believes raw milk was the likely source of an E. coli contamination in Little Qualicum Cheeseworks’ Qualicum Spice cheese.

On Nov. 13, five people in B.C. became sick after consuming products from Little Qualicum Cheeseworks, prompting a warning from the BCCDC.

For several months, the BC Centre of Disease Control and Vancouver Island Health Authority worked with Little Qualicum Cheeseworks, going through the cheese-making process with the company, checking procedures, ingredient and equipment, said Sion Shyng, food safety specialist with the BCCDC.

New Zealand – Shellfish biotoxin alert – between Granville Point and Cape Karikari

MPI

Map highlighting in red the areas affected.

The Ministry for Primary Industries (MPI) today issued a public health warning advising the public not to collect or consume shellfish harvested from the Northland area between Granville Point and Cape Karikari (Whakapouaka). This warning includes Houhora and Rangaunu Harbours.

Routine tests on shellfish samples taken from this region have shown levels of Paralytic Shellfish Poisoning (PSP) toxins above the safe limit of 0.8 mg/kg set by MPI. Anyone eating shellfish from this area is potentially at risk of illness.

Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin) and all other bivalve shellfish should not be eaten.

Note: cooking shellfish does not remove the toxin.

Pāua, crab and crayfish may still be eaten if the gut has been completely removed prior to cooking, as toxins accumulate in the gut. If the gut is not removed its contents could contaminate the meat during the cooking process.
